微滴單細胞包裝系統(tǒng)將單細胞或生物分子包裝進微滴中,為后續(xù)的篩選和分析做準備。它的包裝效率可以達到每秒70000個微滴,且流速可以嚴格控制。這臺設備使得快速且敏感地檢測微滴中單個細胞分泌的或者細胞相關的蛋白成為可能。 這一包裝系統(tǒng)不影響細胞活性,由于微滴的大小和體積有很大范圍的可變性,因而能夠用于不同大小的細胞類型。這些微滴被新式的表面活性劑穩(wěn)定,細胞能夠在其中生長,甚至能培養(yǎng)或保存許多天

為什么選擇Cyto-Mine ? 為什么選擇ESI-MineTM?
在合成生物學領域中,我們的ESI-Mine平臺可以用于高通量質譜(MS)分析。這一技術能夠檢索在質譜分析中通常被破壞的活拷貝,當分析稀有蛋白或細胞庫時這點尤其重要。
應用實例:
1. 我們的技術如何提高初始B細胞的分析
2. 我們的系統(tǒng)用于初始B細胞分析的獨特優(yōu)勢
我們都知道整個研究過程中維持細胞活性的重要性,特別是處理敏感細胞時。這就是為什么我們的技術需要保證初始B細胞的高活性,使得細胞在微滴中生長并分析。如下圖所示,300pL微滴中的細胞在4小時孵育期中保持活性,大部分的工作流程由我們的系統(tǒng)完成。初始B細胞分析中活性是非常重要的,在細胞篩選和分選后經(jīng)常也需要保持健康,才能用于下游的應用。

英文介紹:
OverviewOur research instruments are designed to assist you in finding highly valuable and rare biological variants among vast cell populations. By increasing speed and reducing cost, our picodroplet technology can help you save resources whilst boosting your chances of success. Unlike our industrial instruments, our research instruments are semi-automated rather than fully automated. While this means they require slightly more user input to configure, it also means that they are more flexible and can be easily adapted to fit the needs of your unique research project. We currently have two research instruments that enable you to generate, isolate, and dispense picodroplets for a range of applications. These are the Picodroplet Single Cell Encapsulation System and the Picodroplet Single Cell Assay and Isolation System. Both are compatible with our range of specialist chemicals and biochips. Some common research areas where our instruments have been used previously include biopharmaceutical discovery, bioprocessing, diagnostics, drug-resistance studies, enzyme evolution and synthetic biology. Scroll down for more information on our instruments, or alternatively, contact one of our experts to discuss your needs. ![]() Picodroplet Single Cell Encapsulation SystemOur semi-automated system encapsulates single cells or biomolecules into picodroplets, ready for downstream screening and analysis. It does this at a rapid rate of up to 70,000 picodroplets per second, and the flow rate can be highly controlled. The instrument enables rapid and very sensitive detection of secreted or cell-associated proteins produced by an individual cell, contained in each picodroplet. The encapsulation system doesn’t affect cell viability, while the wide range of picodroplet sizes and volumes gives it flexibility for use with various cell types – large or small. These picodroplets can be stabilised using novel surfactants and cells can be grown in them, and even incubated or stored for many days.

![]() Picodroplet Single Cell Assay and Isolation SystemOnce the cells have been encapsulated in picodroplets, this semi-automated system is able to process, sort and isolate them for easy analysis. We know how time-consuming single cell analysis can be, and that’s why our system is capable of processing picodroplets at a rate of up to 12,000 per minute – giving you more time to spend analysing your data rather than on preparing and processing your samples. The system supports a range of picodroplet sizes and volumes, and the flow rate can be controlled. It’s also equipped with various optical detection methods (e.g. absorbance, scatter, fluorescence) to make it suitable for a range of research applications.
