for non-adherent cell, you can directly culture it in suspending 0 B# U) f& {( L1 gfor adherent cell, you firstly make cells pellet. you do not disperse the cells pellet and directly culture the pellet. the cells will form cells clustered spheroid: ?6 m+ ]- d' B% `2 L
the spheroid size depend on original cell number. Your question is not that clear. please, post your question in detail. 作者: KINGxuridongshe 时间: 2014-6-1 22:02
sorry, I do not have lung cancer cell line in hand. Well, the cell cycle length of A549 cell is approximately 36 hours, and is longer than other tumor cell line. time for forming sphenoid of A549 will be longer. ' [3 [6 E- \4 O0 C3 q9 v% L& f; @6 c; T& ~
to make cell sphere, if i did the work, I am going (1) to pellet 50000 cells in tip of eppendorf. Next, I will (2) discard PBS ( in last wash), (3) gently add 100 micro-liter FBS. (4) keep cells in eppendorf until pellet is floating. (5) transfer pellet to the 96 well plate. 作者: zz091115 时间: 2014-6-5 10:09
