Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Human Tryptase beta ‑2/TPSB2 (Catalog # 3796-SE)

Immunoprecipitation

25 µg/mL

Conditioned cell culture medium spiked with Recombinant Human Tryptase beta ‑2/TPSB2 (Catalog # 3796-SE), see our available Western blot detection antibodies

Neutralization

Measured by its ability to neutralize Recombinant Human Tryptase beta ‑2/TPSB2 (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.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: Tryptase beta-2/TPSB2

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.
