Aria Application Examples

Our automated perfusion system can be used for a wide range of applications including ones that synchronize with microscopy.

Examples are as follows:

Neuron cell immunolabeling in microfluidic chips: Aria facilitates parallel neuronal cell immunofluorescence in up to four microfluidic chips. By automating the cell immunolabeling process, users can significantly reduce the time and effort required to perform the experiment while ensuring consistently stained cells with minimal cell damage and no antibody residue.
Calcium imaging in neuron cells: Using Aria allows full automation of calcium imaging in neurons, expediting numerous microfluidic experiments. This ensured stable recordings, enhancing reliability and reproducibility.
Cancer cell capture and labeling: Aria can deliver up to 10 different solutions, automating the entire process of capturing and labelling MDA-MB-231 breast cancer cells. This includes surface treatment, injection of antibody-coated beads, cell suspension, and immunostaining. This streamlines cancer cell analysis, saving time, reducing reagent usage, and minimizing error margins.

Immunofluorescence of neuron cells

Why use an automated perfusion system for spatial omics? 

Applications like DNA hybridization, high-resolution spatial transcriptomics, DNA paint, FISH, immunolabeling, and tissue profiling require high-resolution microscopy as they target nanometric structures inside the cells. Many of these experiments require long imaging times which can now be automated.

WEBINAR REPLAY – Automated fluid delivery for cell and tissue imaging

Want to gain time, precision and reproducibility for your immunofluorescence assay, or any other assay requiring injection of multiple solutions on your sample? Watch our webinar to learn how to interface a flow chamber (or microfluidic chip) to our automated fluid delivery device ARIA. This will allow you to deliver up to 10 different solutions in a sequential and autonomous manner. In addition, ARIA can be synchronized with any microscope to launch an image acquisition cycle and resume the perfusion protocol once the imaging cycle has been completed.

This all-in-one workflow facilitates alternation between cycles of injection/incubation time with reagents and image acquisition, a feature particularly well-adapted to complex cell and tissue imaging. Here we will present some example applications such as multiplexed tissue imaging, DNA-PAINT and seqFISH, as well as cell capture and staining.

WEBINAR REPLAY – How to turn your fluorescence microscope into a spatial omics platform

Current approaches in genomics, transcriptomics, and proteomics yield quantitative abundance analysis of biomolecules on an almost routine basis, with a critical impact in the life sciences.

However, coupling this high content to spatial information in a single-cell and tissue context is still a challenge, and this is where our efforts are presently focusing.

In this webinar, I will share my facility’s experience in building spatial omics platforms.

First, I will provide an overview and comparison of microscopy-based methods for spatial omics. Then, I will present details and resources on how to build such a platform.

Finally, I will show the existing tools available for image and data analysis associated with these methods.

It is my hope that our experience can serve others in the road ahead to help decide which technique is best for their applications and to assist in their implementation.

Reduce experimental error

Manually changing solutions under the microscope presents several challenges:

Risk of displacing the dish and recorded positions of Regions of Interest (ROI)
Potential loss of samples
Increased risk of sample contamination
Possibility of liquid spillage over the microscope
Errors in the sequence of solutions due to the complexity of the process

Having an automated fluidic system reduces experiment duration, which can extend up to 4-5 days per experiment and requires constant scientist presence.

	Pipette	Aria
Type of injections	Abrupt injection (up to 1mL in few seconds) Disparate injections Turbulent flow	Smooth & controlled injections Identical injections Laminar flow

Seamless integration through our dedicated SDK 

An SDK library allows users to customize the software to interface with external devices. This feature facilitates creation of exciting protocols with great potential, like the one featured in Nature Protocols. The authors developed an iterative immunolabeling and chemical bleaching method, called iterative bleaching extends multiplexity (IBEX), that enables multiplexed imaging (>65 parameters) in diverse tissues, including human organs.

“I got to test Aria automated sequential injection system in my research project in a collaboration with Fluigent. More precisely, Aria injection system helped me automatize the capture process and immunostaining of breast cancer cells under a very precise and controlled flow rate. The software interface is so user-friendly that I was being able to follow in real-time the progression of my experiment. The amazing part is that ARIA even calculated the total amount of time required for each step and helped me avoid the waiting time in front of my setup! It made my experiment go as smoothly as possible.”

Aria SDK

The SDK library collects the available software functions for users that wish to integrate our liquid handling functions into their own software for automated workflows, allowing them to have a single interface to actuate all components that are part of their fluorescence microscopy system (fluid management unit, imaging unit, heating devices, incubator, etc.).

schematic of ARIA Automated sequential injection system

To save time and minimize reagents consumption, the system loads its internal and external tubing with the successive solutions to inject in the chip. 

Working principle

If the protocol commands to inject 40 µL of solution A, incubate for 1 hour, inject 50 µL of solution B, incubate for 1 hour then wash with buffer for 5 minutes and the total volume of tubing ( internal + external) is of 300 µL Aria will prefill tubing as follows:

As a consequence, calibration of the tubing length and related volume is necessary.

ARIA Automated sequential injection system Working principle

Here is a description of all the functions available to optimize protocol writing in Aria

Calibration

Calibration is automated and the software assists the user to determine the total volume of his step up (internal volume + L1+L2). Calibration values are recorded for future experiments.

Prefill

Initially all tubing inside Aria is dry. The “Prefill” function is recommended as a first step to load all solutions inside the device without injecting air in the chip or chamber. This function can be deactivated if the user performed the loading manually. Fluigent strongly recommends using this function. 

Perfusion/injection

Perfusion can be set in terms of volume (ex: step 1) or duration (ex: step 2) of injection. 

The user selects the reservoir of the solution to inject (ex: reservoir 1), sets the flow rate (ex: 100 µL/min) at which the solution will enter the flow cell and the volume (ex: 100 µL) or duration (ex: 1min) of injection. The flow rate  range is from 40 µL/min to 1 mL/min. The software automatically calculates the time at which the solution should enter the flow cell. 

Incubation / wait

Incubation time can be easily set by entering the duration of the incubation (ex: 1h30) in the ‘wait’ function. 

The ‘wait for user’ function is a variation of the ‘wait’ function. It is particularly useful if the user must perform a manual operation like preparing cells before injection. The system waits until the user notifies that it can proceed to the next step. In absence of notification by the user, the system proceeds to the next steps after 12 h. 

Clear tubing

To prevent contamination between perfusion, the tubing can be cleared with a buffer using the ‘Flush tubing’ function. The user selects the reservoir containing the wash solution (ex: reservoir 10) and the flow rate at which the tubing is flushed (ex: 100 µL/min). 

Aria pushes all the residual fluids contained in the L1 tubing to waste and fills the L1 with wash solution. The Buffer contained in L1 will also be directed to the waste. This operation does not involve flow to the chip as neither residual fluids nor buffer enter the chip. However, the residual fluid contained in L2 will not be cleared. For this reason, Fluigent  recommends the user to keep L2 as short as possible. 

External synchronization

Aria is equipped with TTL and TCP signalling and can send and receive both signals. 

Sending TTL or TCP

Each step is flanked by two bells () : at the front and back of the settings (see below for ‘volume injection step).

Click on each bell to begin activation. they get activated (). Aria will then send a TTL or TCP signal either when the step starts (example below) or ends or both. 

Fluigent recommends using this function to synchronize perfusion and imaging.

Receiving TTL or TCP

The ‘Wait for Signal’ function puts the Aria on hold. The Aria then waits for an external signal, either TTL on input port or TCP, to run the next steps.  If the Aria does not receive   signaling after 12 hours, it automatically proceeds with next steps. 

Minimum volume reservoir

Fluigent’s Aria is designed to minimize reagent consumption. An additional volume of liquid (36µL) is necessary to preload the system and to ensure that some residual liquid is still present in reservoir after perfusion to prevent delivery of air to the system. 

As the user writes his protocol, the software calculates the minimum volume that should be placed in each reservoir to successfully run the protocol. 

Write, load, save sequence

To design a new sequence, click on “Create new sequence”.

Before running a sequence, the software will automatically ask the user to save it.

All saved sequences are accessible and can be loaded by clicking on “Load sequence”.

Recorded data

For each experiment, the system automatically records and saves the flow rate, pressure, the reservoir from which the solution is withdrawn if solution is delivered to the chip or waste. All data is accessible by clicking on “open logs folder”
