HA-Tag (6E2) Mouse mAb (Alexa Fluor® 647 Conjugate) #3444
|IF-IC F||All||Transfected Only||Mouse IgG1|
Reactivity Key: All=All species expected
Species cross-reactivity is determined by western blot.
Specificity / Sensitivity
HA-Tag (6E2) Mouse mAb (Alexa Fluor® 647 Conjugate) 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.
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® 647 under optimal conditions with an F/P ratio of 2-6. The Alexa Fluor® 647 dye is maximally excited by red light (e.g. 633 nm He-Ne laser). Antibody conjugates of the Alexa Fluor® 647 dye produce bright far-red-fluorescence emission, with a peak at 665 nm.

Confocal immunofluorescent analysis of COS cells, untransfected (left) or transfected with an HA-tagged protein (right), using HA-Tag (6E2) Mouse mAb (Alexa Fluor® 647 Conjugate) (blue pseudocolor) and Di-Methyl-Histone H3 (Lys27) Antibody #9755 (green). Actin filaments were labeled with DY-554 phalloidin (red).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 647 fluorescent dye and tested in-house for direct flow cytometry and immunofluorescent analysis in cells transfected with HA-tagged protein.
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).
