各位老师,请教两个问题:) J3 t, [3 U1 s3 ^4 F* O7 ^' l! ^
1、冻存的肿瘤组织 还能否取干细胞?2 D/ b. U3 Z9 P9 i
2、我一个操作手册上看到这样的步骤:! |3 k7 ^! F( q( G* j _$ H
a The digested tissue was resuspended in 10 ml of PBS 1× and triturated by passing it in a tissue sieve (0.38 mm, 40 mesh) and recovering the cells in a 100-mm dish.3 q+ p; Z o& g7 j) r8 X
b. The recovered cells were then passed through a 70- mm cell strainer (BD Biosciences) and collected in a 50-ml centrifuge tube.( `1 P& W" f# `9 s
请问其中的tissue sieve与cell strainer分别是指什么?试剂商说他们只有那种200目得细胞滤网。6 d- T- L* y6 s
