sequence然后4-6个月后就可以有抗体的那种service。
多谢!! |

F**********6 发帖数: 90 | 4 建议自己表达纯化一点蛋白做抗原,这样抗体成功率高很多倍。我做了三个,有两个做
IF WORK得非常好。
用合成的PEPTIDE做抗原,我所经历的,成功率只有10%左右。 |

c********b 发帖数: 363 | 6 先谢谢楼上各位。不知道有没有人用过sigma的service。我对genscript的peptide
service没有信心,买过一次,提高了100X的浓度还看不到多个实验室反复报道的现象。
我已经做了一个Ab,用的cocalico的service,象你提到的那样。能用来做WB,IP就很
难了。
然后发现我做的蛋白有alternative splicing,做的抗体能识别两个form,现在发现第
三个form也不能忽略,所以想再做一个抗体。还以为用peptide的特异性会高一些呢。
是不是自己表达一个50aa的peptide效果更好?
再次感谢!

R*****o 发帖数: 12 | 7 表达蛋白和peptide没啥大的区别,文献中报道利用蛋白做抗原最后产生的也是1-2个优
势表位且以线性表位为主。不过peptide最大的问题应该是预测的线性表位是否准确的
问题,所以要是做一条肽的话成功率会很难保证,很可能Elisa识别peptide很好但是不
能识别内源。不过如果预测好一点或者多选择几条的话,应该还是不错的。
另外有的公司也提供可溶表达的服务,比如上面说的Abmart,可以利用可溶表达蛋白和
多肽两种方法同时做。 |
