Description

Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Immunogen

synthetic peptide corresponding to amino acid residues 98-106 (YPYDVPDYA) of human Influenza virus hemagglutinin (HA) known as HA-tag, conjugated to KLH.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide

Application

Anti-HA antibody is suitable for use in immunoprecipitation and western blot.
It is also suitable for indirect immunofluorescence (10-20μg/mL using HA-tagged fusion protein transfected cells), immunoprecipitation (2.5-4μg/test using HA-tagged fusion protein from cell lysates), and western blot (0.5-0.8μg/mL using HA-tagged fusion protein transfected cell extracts).

General description

Hemagglutinin (HA) is an influenza-virus glycoprotein that regulates membrane fusion and receptor-binding functions during viral entry and infection . The HA gene is often used as an affinity tag for target proteins in recombinant expression vector systems. The HA-tagged proteins produced from such systems yield stable fusion products that do not interfere with the function and distribution of target proteins
Anti-HA antibody is specific for N- or C-terminal HA-tagged fusion proteins. The product may detect cross-reacting bands in certain mammalian cells. The immunizing HA peptide (Product No.I2149) specifically inhibits the staining of the HA-tagged protein band.

These documents are located on the product detail page under Useful Links & Tools. Click on the following link to search for a Certificate of Analysis. Please click the following link to see the details on our Product Dating Information.
How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
How do I find price and availability?
There are several ways to find pricing and availability for our products.  Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers. 
What is the concentration of Product No. H6908, anti HA?
The antibody concentration for Product No. H6908 is reported as a lot-specific value on the certificates of analysis. Please refer to the Certificate of Analysis for the lot received for the specific antibody concentration. Values for recent lots have ranged from 0.5 - 0.7 mg/mL.
Is the immunizing peptide for Product H6908, Anti-HA antibody, available?
The immunizing peptide is Product No. I2149. It is useful for displacement of HA-tagged fusion proteins from HA antibody in immunoassays. The successful inhibition of antibody binding by HA peptide demonstrates the binding of the antibody is specific.
What strain of influenza hemagglutinin does Product H6908, Anti-HA antibody, recognize?
The sequence of the immunizing peptide is YPYDVPDYA. This sequence corresponds to amino acids 99-107 of human influenza virus X47 (classified as an H3N2 strain) referred to in Niman, H.L., et al., Proc. Natl. Acad. Sci. USA, 80, 4949-4953, 1983. However, according to the NCBI databases, the same epitope (YPYDVPDYA) corresponds to amino acids 98-106 in the vast majority of prevalent influenza viruses hence our claim in the data sheet of the antibodies. NCBI is National Center for Biotechnology Information, http://www.ncbi.nlm.nih.gov
What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS. To access the shipping information for this material, use the link on the product detail page for the product, or search here.
