Drop-seq chip


    Drop-Sequencing PDMS Chips

    Our Drop-seq chip is a PDMS Chip containing  22 operational designs including a Silane hydrophobic coating. 

    Drop-seq chip advantages:

      • High throughput results in a short period of time
      • Minimize consumption of expensive samples
      • Prepare a single-cell suspension from a tissue
      • Analyzes sequences of single cells in a highly parallel manner
      • Unique molecular and cell barcodes enable cell- and gene-specific identification of mRNA strands
      • RT with template-switching PCR produces high-yield reads from single cells

    Main benefits
    • droplet monodispersity

      Highly monodisperse droplets

    • Robust

      Durable over a wide range of parameters

    • Efficient

      Efficient production of transcript libraries

    Single-cell RNA-sequencing (scRNA-seq) has revolutionized biomedical research by enabling the in-depth analysis of cell-to-cell heterogeneity of tissues with unprecedented resolution. Among several existing droplet-based approaches, the Drop-seq method has emerged as one of the most widely used systems.

    Drop-Seq is a low-cost, high-throughput platform to profile thousands of cells by encapsulating them into individual droplets. Uniquely barcoded mRNA capture microparticles and cells are coconfined through a microfluidic device within the droplets where they undergo cell lysis and RNA hybridization. After breaking the droplets and pooling the hybridized particles, reverse transcription, PCR, and sequencing in single reactions allow to generate data from thousands of single-cell transcriptomes while maintaining information on the cellular origin of each transcript. More details about the mechanism and application of Drop-seq.

    Why use PDMS for Drop-seq chip?

    PDMS is used to fabricate microfluidic devices (single layer and bilayer) and micro-imprint stamps. Two different types are commonly used by researchers for these applications: PDMS RTV-615 and PDMS Sylgard 184.

    • It is deformable, which allows the integration of microfluidic valves using the deformation of PDMS micro-channels, its use to detect very low forces (biomechanics interactions from cells)…
    • It is easy to mold. The PDMS can mold structures at high resolutions. Also, PDMS bonds tightly to glass or another PDMS layer with a simple plasma treatment.
    • It is inexpensive compared to other materials. 
    • It is generally biocompatible.

    Features of Drop-seq chip

    Dedicated to Drop-seq

    Each Droplet Generation Device is based on the design recommended in the latest McCarroll lab Drop-seq protocol, ensuring the best chances of success.

    More than 22 experiments per chip

    22 Droplet Generation Devices per Chip Provides value for money in a chip that lasts. When the life of one device is depleted, simply move on to the next one.  Besides, our drop-seq chip rapidly creates libraries ready for high throughput sequencing.

    Efficient production of transcript libraries

    Superior design promotes optimal mixing of component fluids, thereby minimizing bead shearing or premature lysis of cells and mRNA release.

    Libraries from each cell are uniquely bar coded and they can practically barcode over a million cells per experiment.

    The library generation and bar coding workflow is fast, simple, rugged and robust.

    Drop-seq applications

    drop seq chip

    Drop seq is becoming widely used across biological disciplines including Development, Neurology, Oncology, Autoimmune disease, and Infectious disease:  nanoparticles fabrication, emulsions and foams, drug delivery, but also as tiny reaction chambers for PCR and reverse transcription. 

    Science recognized these advances as the 2018 Breakthrough of the Year
