Protocol

Specificity / Sensitivity

HA-Tag (E3F8G) Mouse mAb detects recombinant proteins containing the HA epitope tag. The antibody recognizes the HA-tag fused to either the amino or carboxy terminus of targeted proteins in transfected cells. This antibody detects a non-specific band of unknown origin in mouse cell line extracts at 70 kDa.

Species Reactivity:

All Species Expected

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide containing the influenza hemagglutinin epitope (YPYDVPDYA).

Background

Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein’s biochemical properties.

The HA-tag is derived from an epitope of the influenza hemagglutinin protein, which has been used extensively as a general epitope tag in expression vectors (1).
