√ 4个独立的荧光检测通道
√双高速显微镜可设置载玻片的过程分析
√基于机器人视觉技术的内联液滴分析
√无限制芯片(兼容各种弹性体芯片)
√集成化高压脉冲发生器
√嵌入式用户界面软件
√占用空间小
Styx平台为基于液滴的功能筛选分析提供了一个易于使用的框架,与传统板基技术相比,该平台的筛选吞吐量提高了>1000倍。
技术原理:
单细胞RNA-seq和单细胞ATAC-seq技术被广泛用于为广泛的生物体、组织和疾病过程创建细胞类型图谱。为了增加这些地图集的规模,降低成本,并允许更专业的多组检测,定制液滴微流体可以为商业安装提供补充解决方案。
我们开发了HyDrop,一个灵活的通用液滴微流控平台,包含三个方案。
第一种方案,是用定制的低聚物制造可溶解的水凝胶珠,这些低聚物可以在水滴中释放出来。
第二个方案,我们将这些珠用于液滴中的HyDrop-ATAC,这是一种低成本的协议。在验证HyDrop-ATAC后,我们将其应用于快速冷冻小鼠皮层,在一次运行中生成了8502份高质量的单细胞染色质可及性谱。
第三种方案,我们采用条形码水凝胶珠的反应化学和捕获序列来捕获mRNA,与以前基于开源水滴的sCRNA-seq分析(Drop-seq和inDrop)相比,在吞吐量和灵敏度上有显著提高。HyDrop目前能够以高通量和更低的成本生成单细胞数据,我们预计HyDrop可以进一步发展,与新型(多)组学协议兼容。

Product introduction:
STYX is a complete solution for any laboratory that customers want to adopt an advanced droplet microfluidic workflow. This platform can realize various applications of droplet cell counting and on-demand operation. STYX combines fluorescence analysis and droplet processing systems with easy-to-use software, making it the perfect solution for functional screening workflows.
Main technical features of STYX droplet microfluidic high-throughput screening analysis system:
√ Up to 4 independent lasers (405/488/561/633) can be configured
√ 4 independent fluorescence detection channels
√Dual high-speed microscopes can be set for process analysis of slides
√Inline droplet analysis based on robot vision technology
√Unlimited chips (compatible with various elastomer chips)
√Integrated high voltage pulse generator
√ Embedded user interface software
√ Small footprint
The Styx platform provides an easy-to-use framework for droplet-based functional screening and analysis. Compared with traditional plate-based technology, the platform's screening throughput has increased by >1000 times.
Technical principle:
Single-cell RNA-seq and single-cell ATAC-seq technologies are widely used to create cell type maps for a wide range of organisms, tissues, and disease processes. In order to increase the scale of these atlases, reduce costs, and allow more professional multi-group inspections, customized droplet microfluidics can provide complementary solutions for commercial installations.
We have developed HyDrop, a flexible general-purpose droplet microfluidic platform, which contains three solutions.
The first option is to use custom-made oligomers to make soluble hydrogel beads, which can be released in water droplets.
In the second solution, we use these beads for HyDrop-ATAC in droplets, which is a low-cost protocol. After verifying HyDrop-ATAC, we applied it to the rapid freezing of mouse cortex and generated 8502 high-quality single-cell chromatin accessibility profiles in one run.
In the third scheme, we use the reaction chemistry and capture sequence of barcode hydrogel beads to capture mRNA. Compared with the previous sCRNA-seq analysis based on open source water droplets (Drop-seq and inDrop), it has significant throughput and sensitivity. improve. HyDrop is currently able to generate single-cell data with high throughput and lower cost. We expect HyDrop to be further developed and compatible with new (multi)omics protocols.
Application areas:
? Single cell analysis
? Cell sorting
? Cell sequencing
? Drug screening
? Synthetic biology
? Antibody discovery
? Directed evolution
? Astrobiology
Applications
Single cell analysis:
Single-cell analysis of the immune microenvironment of breast tumors, coupled with computational analysis, generated an immune map of breast cancer, indicating the continuous T cell activation and differentiation status.
Achieved:
Single-cell RNA-seq shows expansion of immune cell phenotype in tumor
Biscuit identifies cell population patterns that differ in co-expression
T cells reside on a continuous trajectory of activation and differentiation
Combining environmental input and TCR use to shape T cell phenotype
