Expression. With this technique, gene expression can end up easily monitored on traditional western blotting, immunoprecipitation and immunofluorescence thanks to an antibody that recognizes this epitope. Amino acid sequences which were widely used for epitope tagging are as follow; YPYDVPDYA (HA-Tag), EQKLISEEDL (Myc-Tag) together with YTDIEMNRLGK (VSV-G-Tag), which match the partial peptide with Influenza hemagglutinin protein, the Human c-myc gene product and also the Vesicular stomatitis virus glycoprotein respectively. Monoclonal antibody HAYA. 11 (HA, 16B12, flu tag) was raised against the twelve amino chemical p peptide CYPYDVPDYASL. This second-generation HA antibody is a good substitute for the 12CA5 monoclonal Anti-SMAD3,Anti-Desmin Antibody,HA Antibody antibody. HAYA. 11 recognizes the influenza hemagglutinin epitope (YPYDVPDYA) that's been used extensively for a general epitope tag with expression vectors. The extreme specificity of the antibody allows unambiguous identification and quantitative analysis of the tagged protein. The HA. 11 antibody recognizes HA epitopes located during protein sequences as well as at the N- or C-terminus. 95% homogeneity as a result of standard chromatographic techniques. Anti-HA is developed in rabbit which has a synthetic peptide corresponding to help amino acid residues 98-106 (Tyr-Pro- Tyr-Asp-Val-Pro-Asp-Tyr-Ala) of the human Influenza hemagglutinin (HA), conjugated to KLH. This antibody is affinity-purified on the immobilized immunizing peptideAnti-HA can be utilized for immunoblotting of recombinant proteins tagged with HA at the amino or carboxy terminus. This antibody may recognize cross-reacting bands in certain mammalian cells. Staining in the fusion protein band is specifically inhibited with the immunizing HA peptide (Product or service No. I 2149). The antibody is usually useful for detection with HA-tagged fusion proteins just by immunoprecipitation and by immunofluorescent yellowing of transfected cells. Recombinant DNA technological know-how enables the attachment involving genes of interest to help specific sequences or family genes, which can provide 'affinity handles' (tags) that will enable the selective identification and purification with the protein of interest. 1-6 The addition of an tag to a given gene creates a stable fusion product that does not appear to interfere while using the bioactivity of the health proteins, or with the biodistribution with the tagged product. Influenza hemagglutinin protein is a nonapeptide derived from this major spike membrane glycoprotein with the human influenza virus. This strain specific glycoprotein is a homotrimer of 84 kDa monomers, just about every containing two disulfide-linked subunits: HA1 together with HA2. The nucleic acid sequence encoding the HApeptide has been incorporated into various expression plasmids adjacent to this cloning site thus allowing the cloning and phrase of HA-tagged fusion healthy proteins. Such fusion proteins may very well be expressed in cells with various organisms: bacteria, get rid of, insects and mammals. Inside fusion protein, the HA sequence may serve for a recognition target for certain antibodies thus enabling recognition, subcellular localization, characterization, quantification, practicable analysis and affinity purification with the HA-tagged protein and linked bound proteins. 4.
