Informations générales

Protein tags are protein or peptide sequences located either on the C- or N- terminal of the target protein, which facilitates one or several of the following characteristics: solubility, detection, purification, localization and expression. The HA tag is corresponds to amino acid residues YPYDVPDYA of human influenza virus hemagglutinin(HA). 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. This tag facilitates the detection, isolation, and purification of the proteins. The HA tag is useful in western blotting and immunohistochemical localization of expressed fusion proteins when examined with antibodies raised specifically against the HA-tag.

Kiara (Verified Customer) (07-28-2025)

This primary antibody did give a signal for HA-tagged dCas9-KRAB in our CRISPRi iPSC-CMs, but however it also gave quite some background in our WTC11 negative control line.

Victor (Verified Customer) (06-13-2022)

I'm using the antibody for Western blotting tissue culture samples and it works well for my needs for the price. I've been using a 1:2000 dilution which gives me decent bands via Western blot and analyzed using a fluorescent anti-rabbit secondary. The bands could be a little brighter, but this antibody is worth it for the sale price. It's stored in glycerol, so it saves you the trouble of aliquoting and it can be kept at -20 which is nice.

• Applications: Western Blot
• Primary Antibody Dilution: 1:2000
