Anti-TPSAB1 Antibody

Raised in rabbit and purified by antigen-affinity chromatography, this polyclonal antibody from Antibodies.com is directed against TPSAB1 (tryptase alpha/beta 1), a serine protease expressed in mast cell granules. The immunogen is a recombinant human TPSAB1 protein, and the reagent recognizes endogenous total TPSAB1 without a conjugated tag. It is supplied at 1.0 mg/mL in a 50 µL volume, formulated in phosphate-buffered saline at pH 7.4 containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, and is shipped from Cambridge, UK with a typical lead time of four to six business days. Validated applications include Western blotting (WB), immunohistochemistry (IHC), and immunocytochemistry/immunofluorescence (ICC/IF), and the antibody has been confirmed to react with Human, Mouse, and Rat samples, making it suitable for cross-species mast-cell tryptase studies in tissue sections and cell preparations. As a polyclonal reagent, it offers an epitope-diverse response useful for detecting the full-length tryptase in mast cell tryptase research, while the unconjugated format allows flexible pairing with secondary detection chemistries of the researcher's choice. The product is intended for research use only and is not validated for diagnostic or therapeutic applications; it should be stored according to standard -20 °C antibody handling protocols to preserve activity.
