Applications for Human Tryptase alpha/beta-1 Antibody

Application
Recommended Usage

Immunoprecipitation

25 µg/mL
Sample: Conditioned cell culture medium spiked with Recombinant Human Tryptase alpha/beta-1 (Catalog # 3796-SE).

Western Blot

1 µg/mL
Sample: Recombinant Human Tryptase alpha/beta-1 (Catalog # 3796-SE)

Neutralization

Measured by its ability to neutralize Recombinant Human Tryptase alpha/beta-1 (0.5 µg/mL, Catalog # 3796-SE) cleavage of the fluorogenic peptide substrate Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (10 µM, Catalog # ES002). The Neutralization Dose (ND50) is typically 1.4 µg/mL.

Background: Tryptase alpha/beta-1

Tryptases are trypsin-like serine proteases, and beta tryptases appear to be the main isoenzymes expressed in mast cells (1). They are stored in secretory granules of mast cells, where they form active tetramers with heparin proteoglycan. Because of the unique arrangement of the active sites in the tetramer, which are facing a narrow central pore, beta tryptases are resistant to macromolecule protease inhibitors (2). When mast cells are activated, beta tryptases are released along with other proteins in secretory granules, participating in provoking inflammatory conditions (3). beta tryptases have been implicated as mediators in the pathogenesis of asthma and other allergic disorders.
