T****r 发帖数: 9 | 1 hybridoma一般很容易复苏,但是有时候如果冻存条件不好有可能遇到复苏困难的情况
。细胞往往开始看起来很好,但是根本长不起来。这种情况一般是因为真正有活性的细
胞比例太小的原因。因为hybridoma具有cluster生长的优势,很多paracrine
sufficient的信号有利于生长。如果长不好的话建议用hybridoma cloning factor 加
在culture
media 中,或者加入feeder cells.

s*******b 发帖数: 1012 | 2 在自己做单抗中,想请教一下版上的大牛,拿到离心过后的hybridoma的supernatant(
没有purification),要如何测量里面IgG的含量?已经有了rabbit IgG whole
molecule可以用作standard。Bradford?BCA? or some other methods? Hybridoma
supernatant里的主要蛋白是不是就是分泌的IgG?多谢多谢 |
|
c*****i 发帖数: 1392 | 3 Hybridoma是最容易复苏的一类细胞了。 37C水浴速融,贴壁的Hybridoma直接加入培养
瓶,2小时后换液,可用20%FBS。悬浮细胞解冻后加1ml培养基,慢速离心1000rpm,
5min,去上清,加新鲜medium,培养。若细胞太少,培养一周后看
10000rpm
了。 |

(55KD)和轻链 (25KD)外,还有一条 带,在轻链下面。 请问这可能是什么原因造
成的呢?
谢谢了!!! |

l*********2 发帖数: 247 | 9 第一次接触Hybridoma cell。细胞从液氮取出后在70%酒精里融化。培养液加热至37度
,替换冻存液,然后细胞在6孔板中培养。24小时后吸取培养液至2ml tube,10000rpm
离心后复加至细胞。24小时有很多贴壁细胞,48小时观察只有少量贴壁,大部分死掉了。
已重配过培养液,不是培养液的原因。
请问板上高手这是什么原因?谢谢! |
|
f*****f 发帖数: 195 | 10 Hybridoma不是典型的贴壁细胞,大部分悬浮,不是死细胞。那些贴着的轻微吹打就下
来了。
70%酒精里融化? 直接37度水浴融化。
10000rpm 太高,1000rpm 5 min足够
10000rpm
了。 |

Buffer。得到的Elution,直接用Millipore的Spin Column清洗加浓缩,选大一些的Cut
(比如50KD),避免小片段污染。
看你的胶,有小片段(~20 KD),可能是蛋白降解,也可能是小片段污染。另,高
分子处还有条带(~200KD),可检查蛋白变性是否彻底。 |
