1、在在文献上看到, the spheres were mechanically dissociated into single cells and diluted into culture medium. The suspended cells were seeded into 96-well plates with the dilution that would result in one cell per well. The single–cell-containing wells were identified by checking the culture wells 2 h after the cell-seeding process. 请问如何确定稀释的浓度以保证one cell per well?具体怎么操作?6 n- F, t& e, }& e% h" q" p

2、冻存的肿瘤组织 还能否取干细胞?一般需要多大的组织块?! B$ r9 X) A# n" R8 r9 {/ u

4、我一个操作手册上看到这样的步骤:4 a5 J/ z/ U; ^0 v4 L1 S! ~+ {
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.6 ^" D9 X& ?; ^9 R) Q0 i; E
b. The recovered cells were then passed through a 70- mm cell strainer (BD Biosciences) and collected in a 50-ml centrifuge tube.
V& o6 J+ e& j' H: k+ m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.请问大家有用过这两个东西的在哪里订购? |
