STYX是一套任何客戶希望采用先進的液滴微流體工作流程的實驗室的完整解決方案。該平臺可以實現液滴細胞計數和按需操作的各種應用。STYX將熒光分析和液滴處理系統與方便使用的軟件相結合,使其成為功能篩選工作流程的完美解決方案。
STYX液滴微流控高通量篩選分析系統主要技術特點:
√ 最多可配置4個獨立的激光器(405/488/561/633)
√ 4個獨立的熒光檢測通道
√雙高速顯微鏡可設置載玻片的過程分析
√基于機器人視覺技術的內聯液滴分析
√無限制芯片(兼容各種彈性體芯片)
√集成化高壓脈沖發生器
√嵌入式用戶界面軟件
√占用空間小
Styx平臺為基于液滴的功能篩選分析提供了一個易于使用的框架,與傳統板基技術相比,該平臺的篩選吞吐量提高了>1000倍。
技術原理:
單細胞RNA-seq和單細胞ATAC-seq技術被廣泛用于為廣泛的生物體、組織和疾病過程創建細胞類型圖譜。為了增加這些地圖集的規模,降低成本,并允許更專業的多組檢測,定制液滴微流體可以為商業安裝提供補充解決方案。
我們開發了HyDrop,一個靈活的通用液滴微流控平臺,包含三個方案。
第一種方案,是用定制的低聚物制造可溶解的水凝膠珠,這些低聚物可以在水滴中釋放出來。
第二個方案,我們將這些珠用于液滴中的HyDrop-ATAC,這是一種低成本的協議。在驗證HyDrop-ATAC后,我們將其應用于快速冷凍小鼠皮層,在一次運行中生成了8502份高質量的單細胞染色質可及性譜。
第三種方案,我們采用條形碼水凝膠珠的反應化學和捕獲序列來捕獲mRNA,與以前基于開源水滴的sCRNA-seq分析(Drop-seq和inDrop)相比,在吞吐量和靈敏度上有顯著提高。HyDrop目前能夠以高通量和更低的成本生成單細胞數據,我們預計HyDrop可以進一步發展,與新型(多)組學協議兼容。

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
