The GST tag antibody can recognize C-terminal, internal, and N-terminal GST fusion proteins.
The glutathione S-transferase (GST, previously known as ligandins) family of enzymes are composed of many cytosolic,
mitochondrial, and microsomal proteins. GSTs are present in eukaryotes and in prokaryotes, where they catalyze a
variety of reactions and accept endogenous and xenobiotic substrates.GST tag antibody can be helpful in detecting the
fusion protein during purification as well as the cleavage of GST from the protein of interest. GST tag antibody has wide
applications that could include your research on GST proteins or GST fusion recombinant proteins.

答：可能的原因有：
1、目的蛋白有多個修飾位點，本身可以呈現(xiàn)多條帶，建議查閱文獻(xiàn)或進(jìn)行生物信息學(xué)分析，獲得蛋白序列的修飾位點信息，通過去修飾確定蛋白實際大小；
2、樣本處理過程中目的蛋白發(fā)生降解,建議加入蛋白酶抑制劑；樣本處理時在冰上操作；
3、雜蛋白多，建議處理目的蛋白；
4、抗體特異性不強，建議使用特異性強的抗體；
5、抗體孵育時間過久，建議減少抗體孵育時間；
6、二抗與抗原有交叉反應(yīng)，建議選擇合適的封閉物；
7、二聚體或多聚體存在，建議增加蛋白質(zhì)變性過程及強度；
8、底物顯色與曝光時間過長，建議縮短顯色及曝光的時間。
