The HA epitope is an expression tag commonly used in protein expression experiments. Compared to its corresponding native protein, a HA-tagged protein will migrate at a larger size on SDS-PAGE, which is equivalent to the size of the epitope tag. The size of the HA epitope may vary depending on the expression vector being utilized, but usually ranges from 3 to 5 kDa. Cayman Chemical’s HA polyclonal antibody will recognize proteins expressed with both N-terminal and C-terminal HA tags.WARNING This product is not for human or veterinary use.
