Hemagglutinin/HA Peptide Antibody (2908F) [Unconjugated]

Western blot shows lysates of rvInflluenza A H1N1 Hemagglutinin. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Influenza A Virus H1N1 Hemagglutinin Monoclonal Antibody (Catalog # MAB113961) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Hemagglutinin at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1

Hemagglutinin was detected in immersion fixed CHO Chinese hamster ovary transfected cells (positive) and absent in Wild type CHO Chinese hamster ovary cells (negative) using Rabbit Anti-Influenza A Virus H1N1 Hemagglutinin Monoclonal Antibody (Catalog # MAB113961) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to cell cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Simple Western lane view shows lysates of rvInfluenza A H1N1 Hemagluttinin, loaded at 200 ng/ml. A specific band was detected for Hemagglutinin at approximately 111 kDa (as indicated) using 25 µg/mL of Rabbit Anti-Influenza A Virus H1N1 Hemagglutinin Monoclonal Antibody (Catalog # MAB113961). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background

Influenza hemagglutinin (HA) is a homotrimeric glycoprotein found on the surface of influenza viruses. HA is responsible for binding influenza virus to sialic acid on the surface of target cells. HA is also responsible for the fusion of the viral envelope with the late endosomal protein when it is exposed to low pH. H1N1 is a subtype of Hemagglutinin in influenza A which also includes Neurominidase protein on its surface.
