General description

EZview Red Anti-HA Affinity Gel is a red colored Anti-HA agarose affinity gel that contains anti-HA monoclonal antibody covalently attached to crosslinked agarose beads.


Binding specificity: HA-tag peptide (N-Tyr-Pro-Tyr-Asp-Val-Pro-Asp-Tyr-Ala-C). It recognizes reduced forms of HA-tagged proteins and is reactive with N or C-terminal HA-tagged fusion proteins.


EZview Red Anti-HA Affinity Gel has been used for immunoblot analysis and immunoprecipitation assay.
Suitable for Affinity capture (immunoprecipitation) of N- or C- terminal HA-tagged fusion proteins from E. coli or mammalian cell.
When performing small-scale affinity capture, such as immunoprecipitation, the affinity matrix is difficult to see in the microcentrifuge tubes. Accidental aspiration of the resin leads to quantitative variability in results. The EZview Red Affinity Gels greatly reduces the risk of pellet loss. EZview resins perform as well as conventional non-colored affinity gels, but allow the user to easily differentiate pellet from supernatant. This correlates to more accurate data because less protein is lost.

Features and Benefits

  • Increased visibility - Red color reduces risk of incidental aspiration
  • Improved recovery of target protein by reduced accidental loss
  • Higher reproducibility - More consistent yields

Other Notes

The affinity gel contains affinity purified anti-HA mouse monoclonal antibody (Clone HA-7) covalently attached to beaded agarose. The HA tag corresponds to amino acid residues 98-106 (YPYDVPDYA) of human influenza virus hemagglutinin (HA).

Physical form

1:1 (v/v) suspension in PBS containing 50% glycerol and 15 ppm Kathon

Plant disease resistance (R) proteins confer protection against specific pathogens or pathogen isolates. R proteins function by recognizing pathogen-encoded avirulence (Avr) proteins and translating this recognition event into an initiation of downstream signaling pathways. Key to understanding this process is...
