请教几个问题:
5 A$ `/ m7 S# h9 f5 g$ X# Y1、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?. k8 u: P9 u" z3 s; `

3、良性肿瘤是否也可培养出瘤?* c, u- \% K! A4 Q) S3 x

4、我一个操作手册上看到这样的步骤:5 b' E3 X9 a: S& |. X$ k) m$ X, E4 w
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.! A( _ {4 r; @5 m
b. The recovered cells were then passed through a 70- mm cell strainer (BD Biosciences) and collected in a 50-ml centrifuge tube.! j' S z) W: x: y H( q% j
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? |
