General description
Anti HA-FITC is a mouse monoclonal antibody derived from the HA-7 hybridoma. It is isolated from ascites fluid and conjugated to fluorescein isothiocyanate, isomer I (FITC). The antibody recognizes the HA tag expressed on the N- or C-terminus on HA tagged H7411proteins. The antibody reacts specifically with HA tagged proteins by immunocytochemistry.
Hemagglutinin (HA) is the major envelope glycoprotein of the influenza virus, along with neuraminidase.
Specificity
The antibody recognizes native as well as denatured-reduced forms of HA-tagged proteins and is reactive with N- or C-terminal HA-tagged fusion proteins expressed in E. coli or in mammalian cells.
Immunogen
synthetic peptide corresponding to a fragment of human influenza virus hemagglutinin (HA) known as HA-tag, conjugated to KLH
Application
Antibody suitable for Immunofluorescence. Recommended concentration 1-5 mg/ml. For immunocytochemistry, use HA tagged fusion protein transfected into mammalian cells, then fixed with paraformaldehyde. Anti-HA-FITC antibody, Mouse monoclonal has been used:
- in the labeling of HA-tagged transient receptor potential melastatin 7 (TRPM7) channel protein for immunocytochemistry studies in lymphoblast cell DT40 and human embryonic kidney cells (HEK-293) cells
- in western blotting detection of spindle-associated proteins in Trypanosoma brucei
- in immunostaining of vascular smooth muscle cells (SMCs) for immunocytofluorescence studies
Biochem/physiol Actions
Hemagglutinin (HA) induces immune response post viral infection. Fluorescein isothiocyanate (FITC) conjugated with the influenza virus HA is majorly used in intracellular tracking of the virus and also in flow cytometric studies.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide as a preservative.
