产品介绍
类器官冻存液是一种即用型细胞冻存品,可用于常规细胞、原代细胞、干细胞和类器官等细胞样本的冻存,可有效提高细胞的冻存效率以及复苏后的细胞活率。该冻存液不含血清,不含任何动物来源成分,含有10% DMSO。 使用说明: 一、类器官(或细胞)冻存 为保证冻存质量,需用生长状态良好的类器官(或细胞)进行冻存实验。 1、收集类器官并经传代消化液消化至寡细胞团或单细胞悬液后,加入预冷的类器官冻存液,吹打混匀并迅速转移至冻存管中。 注: (1) 在收集类器官时,为避免枪头粘附性损耗,可将1mL移液枪头吹打抗粘附液进行润洗枪头。 (2) 每1mL冻存液推荐冻存1x10⁵-10x⁷ 个细胞或对应细胞量的类器官。 (3) 冻存前的类器官消化时间一般为3min,对于多层上皮且体积较大的类器官,应适当延长类器官消化时间。 2、将冻存管放入程序降温盒内(程序性降温盒须提前平衡至室温或4℃),随后立即将降温盒放入-80℃超低温冰箱中;也可将冻存管进行人工梯度降温处理,如4℃静置10min,-20℃保存1h,-80℃保存过夜。 3、次日或12h后将冻存管转移至液氮中长期存储。 二、类器官(或细胞)复苏 1、提前在37℃条件下预热类器官(或细胞)所需的培养基。 2、从冻存容器中取出细胞,在37℃的水浴中快速解冻至冻存管内存物仅剩少量冰渣残留时,转移至超净台内。 3、吸取冻存悬液至15mL锥形离心管中,加入5-10倍体积预热的基础培养基,轻轻混匀。 4、300g离心3min,观察确认是否有细胞沉淀,小心吸弃上清液而不干扰沉淀。 5、根据后续实验需求,使用适量的预热类器官完全培养基重悬细胞,用于后续类器官(或细胞)的培养。
