2021-07-28【讨论】标签抗体要考虑抗原表位吗??

最近要买GST标签抗体，但是看santa cruz的抗体有抗原表位，请问要考虑吗？为什么呢？
例如 GST (1-109):

•epitope corresponding to amino acids 1-109 mapping at the N-terminus of GST of Schistosoma japonicum origin
•recommended for detection of GST fusion proteins and glutathione-S-transferase (GST) of Schistosoma japonicum origin by WB, IP, IF and ELISA
还有Schistosoma japonicum origin 跟我载体pGEX4T-1表达的融合蛋白可用Western Blot吗?它们有什么关系？
十分感谢
