The V5 tag antibody can recognize C-terminal, internal, and N-terminal V5-tag fusion proteins.
The V5 epitope tag is derived from a small epitope(Pk) present on the P and V proteins of the paramyxovirus of
simian virus 5 (SV5). The V5 tag antibody can be helpful in detecting the recombinant proteins, some of which
include transmembrane and secreted proteins fusion protein.

答:可能的原因有:
1、目的蛋白有多個(gè)修飾位點(diǎn),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(diǎn)信息,通過去修飾確定蛋白實(shí)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(shí)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(qiáng),建議使用特異性強(qiáng)的抗體;
5、抗體孵育時(shí)間過久,建議減少抗體孵育時(shí)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(qiáng)度;
8、底物顯色與曝光時(shí)間過長(zhǎng),建議縮短顯色及曝光的時(shí)間。
