“烈冰智造計劃”于2021年9月,成功突破國外技術壟斷壁壘,發布“烈冰智造”第一款,用于單細胞測序的實驗耗材——PanoCell雙通道微孔芯片!該芯片完美適配BD平臺全套原裝試劑,磁珠和Protocol,實現國產芯片和國際主流平臺的完美結合,為單細胞測序提供高質量、高效率、高性價比的服務方案!
1. 自主研發PanoCell微孔芯片,搭配BD Rhapsody單細胞平臺+BD磁珠+BD全套原裝試劑及protocol;
2. 具有豐富的、針對不同樣本類型的單細胞懸液制備經驗,如:外周血、細胞系、新鮮/凍存器官組織、腫瘤組織,確保細胞活性達到測序要求;
3. 擁有成熟的單細胞測序文庫構建技術,一次性完成1000-10000個細胞的文庫構建,真正測全組織中所有細胞類型,做到對樣本中所有類型細胞的全面解析;
4. 具備完善的單細胞測序和實驗質控流程,以及豐富的單細胞測序和數據分析經驗,實現個性化、定制化數據分析服務。
樣本類型:
組織、血液、培養的細胞系、制備好的單細胞懸液
注:若客戶樣本為組織,且無能力進行組織解離來獲取單細胞懸液,烈冰將盡可能提供技術及實驗上的幫助,但因不同類型樣本的特異性,無法保證實驗方法適用于所有類型組織。
質量要求:
1. 細胞活性大于70%
2. 濃度為500-2000細胞/μl
3. 體積不小于200μl
4. 細胞培養基及緩沖液不能含Ca2+和Mg2+
5. 細胞體積小于40μm
BD Rhapsody?單細胞分析系統的誕生基于 BD 在細胞生物學領域 40年的專業技術, 采用CytoSeq技術進行單細胞捕獲。應用烈冰PanoCell微孔芯片(包含20W+的微孔(該數量級遠大于Input細胞數量)),搭配BD平臺磁珠+全套試劑+protocol,保證單孔中的單細胞捕獲。同時避免了傳統微流控系統中存在的概率碰撞影響捕獲效率的問題,采用微孔捕獲相對會有更好的捕獲效率,保證Input細胞的全面使用。
