Informations générales

Protein tags are a protein or peptide sequences located either on the C- or N- terminal of the target protein, which can facilitate solubility, detection, purification, localization, and expression of the target protein. The HA tag corresponds to amino acid residues YPYDVPDYA of a surface glycoprotein -human influenza virus hemagglutinin (HA). The HA tag is commonly used for a variety of research applications including chromatin immunoprecipitation, ELISA, flow cytometry, western blotting, immunocytochemistry/immunofluorescence among of others.

Did not give a reliable signal in our positive cell line (CRISPRi that should have HA-tagged dCas9-KRAB). Additionally, there is quite some background as in both the positive and the negative line (WTC11), the nuclei are stained.

Emile (Verified Customer) (04-08-2025)

This HA Tag Recombinant antibody (81290-1-RR) is by far the best HA antibody I have used. It worked exceptionally well in my hands for immunofluorescence experiments. I tested it on a stable cell line expressing an HA-tagged protein and on cells transiently transfected with an HA-tagged protein, and the results were consistently outstanding. The staining was crisp and specific, with minimal background. I used it at a 1:500 dilution on U2OS cells and achieved excellent results.
