The HA tag antibody can recognize C-terminal, internal, and N-terminal HA-tag fusion proteins.
Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of the
human virus. The HA tag is derived from the HA-molecule corresponding to amino acids 98-106
has been extensively used as a general epitope tag in expression vectors. Many recombinant
proteins have been engineered to express the HA tag, which does not appear to interfere with
the bioactivity or the biodistribution of the recombinant protein.HA tag antibody is a highly
sensitive and affinity monoclonal antibody applicable to HA-tagged fusion protein detection.

答:可能的原因有:
1、目的蛋白有多个修饰位点,本身可以呈现多条带,建议查阅文献或进行生物信息学分析,获得蛋白序列的修饰位点信息,通过去修饰确定蛋白实际大小;
2、样本处理过程中目的蛋白发生降解,建议加入蛋白酶抑制剂;样本处理时在冰上操作;
3、杂蛋白多,建议处理目的蛋白;
4、抗体特异性不强,建议使用特异性强的抗体;
5、抗体孵育时间过久,建议减少抗体孵育时间;
6、二抗与抗原有交叉反应,建议选择合适的封闭物;
7、二聚体或多聚体存在,建议增加蛋白质变性过程及强度;
8、底物显色与曝光时间过长,建议缩短显色及曝光的时间。
