Protocols

Specificity / Sensitivity

HA-Tag (6E2) Mouse mAb (Alexa Fluor® 488 Conjugate) detects 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 mammalian cells.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide containing the influenza hemagglutinin epitope (YPYDVPDYA). The antibody was conjugated to Alexa Fluor® 488 under optimal conditions with an F/P ratio of 2-6.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of COS cells, untransfected (blue) or transfected with HA-tagged Akt3 (green), using HA-Tag (6E2) Mouse mAb (Alexa Fluor® 488 Conjugate).

IF-IC

IF-IC

Confocal immunofluorescent analysis of COS cells, mock-transfected (left) or transfected with HA-tagged protein (right), using HA-Tag (6E2) Mouse mAb (Alexa Fluor® 488 Conjugate) #2350. Actin filaments have been labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5™ (fluorescent DNA dye).

Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometry and immunofuorescent analysis in cells transfected with HA-tagged protein.

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 extensively used as a general epitope tag in expression vectors (1).
