Product Overview
Protein tags are protein or peptide sequences located either on the C- or N- terminal of the target protein, which facilitates one or several of the following characteristics: solubility, detection, purification, localization and expression. The HA tag is corresponds to amino acid residues YPYDVPDYA of human influenza virus hemagglutinin(HA). Many recombinant proteins have been engineered to express the HA tag, which does not appear to interfere with the bioactivity or the biodistribution of the recombinant protein. This tag facilitates the detection, isolation, and purification of the proteins. The HA tag is useful in western blotting and immunohistochemical localization of expressed fusion proteins when examined with antibodies raised specifically against the HA-tag.

The recommended starting dilution for Western Blot is WB 1:5000-20000. Optimal dilution should be determined empirically for each laboratory setup, sample type, and detection system. Use freshly prepared lysates with protease inhibitors; add phosphatase inhibitors if studying phosphorylation-dependent forms of HA-Tag. If background is high, increase blocking (5% non-fat milk or BSA in TBST) and/or increase wash stringency.
This antibody has been experimentally validated in: validated species. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "Synthetic Peptide" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: PBS with 0.02% sodium azide and 50% glycerol pH 7.4.. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
Polyclonal antibodies are produced from immunized animals and may exhibit some degree of lot-to-lot variation in titer, background, and sensitivity. Each production lot is tested for performance against established acceptance criteria. When transitioning to a new lot, run a side-by-side pilot comparison against your previous lot using a validated positive control sample before updating your standard protocol. If significant performance differences are observed, contact our technical support team — titer adjustments may resolve the issue in most cases.
