HA-Tag antibody (Biotin)

Catalog No. ABIN100177

Product Details anti-HA-Tag Antibody (Biotin)

Target: HA-Tag

Reactivity: Please inquire

Host: Rabbit

Clonality: Polyclonal

Conjugate: This HA-Tag antibody is conjugated to Biotin

Application: Western Blotting (WB), ELISA, Immunoprecipitation (IP), Immunohistochemistry (IHC), Immunomicroscopy (IM)

Sequence: YPYDVPDYA

Characteristics: Concentration Definition: by UV absorbance at 280 nm

Immunogen: This antibody was purified from whole rabbit serum prepared by repeated immunizations with the 9-aa epitope tag peptide YPYDVPDYA (11 114-122) from hemagglutinin influenza conjugated to KLH using maleimide. A residue of cysteine was added to the carboxy terminal end to facilitate coupling.

Isotype: IgG

Application Details

Application Notes: 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- terminus of targeted proteins as is 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.  Although not tested, this antibody is likely functional for immunoprecipitation and 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. Biotin conjugated anti-EPITOPE tag antibodies are generally suitable for immunoblotting, ELISA, immunohistochemistry, immunomicroscopy as well as other antibody based assays using streptavidin or avidin conjugates.

Abstract: HA-Tag Products

Target Type: Tag

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 tagged protein’s biochemical properties.   Most often sequences encoding the epitope tag are included with 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.  Supplier produces anti-epitope tag antibodies against many common epitope tags including Myc, GST, GFP, 6X His, MBP, FLAG and HA. Supplier also produces antibodies to other tags including FITC, Rhodamine (TRITC), DNP and biotin.
