HA Epitope Tag (YPYDVPDYA) Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, IHC, WB
Recommend Dilution	Anti-HA is optimally suited for monitoring the expression of HA-tagged fusion proteins. As such, anti-HA/HA can be used to identify fusion proteins containing the HA epitope. The antibody recognizes the HA epitope tag fused to the amino- or carboxy- termini of targeted proteins, as expressed in many commonly used expression vectors. This antibody has been tested by ELISA and Western blotting against both the immunizing peptide and HA containing recombinant proteins. This antibody is likely functional for Immunoprecipitation, Immunocytochemistry, and other Immunodetection techniques. Affinity purification of the polyclonal antibody results in very low background levels in assays and low cross-reactivity with other cellular proteins. Recommended Dilutions ELISA: 1/10,000-1/100,000. Western blot: 1/2,000-1/10,000. Immunohistochemistry: 1/500-1/2,000.
Host	Rabbit
Clonality	Polyclonal
Immunogen	Whole rabbit serum prepared by repeated immunizations with the 9-aa epitope tag peptide YPYDVPDYA (114-122) from Hemagglutinin Influenza conjugated to KLH using maleimide. A residue of cysteine was added to the carboxy terminal end to facilitate coupling.
Specificity	This affinity purified antibody is directed against the HA motif and is useful in determining its presence in various assays. This anti-HA tag antibody detects over-expressed proteins containing the HA epitope tag. To date, it has reacted with all HA-tagged proteins tested. In Western blotting of bacterial extracts, the antibody does not cross-react with endogenous proteins.

Concentration	lot specific
Purification	Affinity Chromatography
Conjugation	Unconjugated
Storage Condition	Store undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Background	Epitope tags are short peptide sequences that are easily recognized by tag-specific antibodies. Due to their small size, epitope tags do not affect the biochemical properties of the tagged protein. Most often, sequences encoding the epitope tag are included with the target DNA at the time of cloning to produce fusion proteins containing the epitope tag sequence. This allows anti-epitope tag antibodies to serve as universal detection reagents for any tag containing protein produced by recombinant means. This means that anti-epitope tag antibodies are a useful alternative to generating specific antibodies to identify, immunoprecipitate or immunoaffinity purify a recombinant protein. The anti-epitope tag antibody is usually functional in a variety of antibody-dependent experimental procedures. Expression vectors producing epitope tag fusion proteins are available for a variety of host expression systems including bacteria, yeast, insect and mammalian cells.
