Granzyme K Monoclonal Antibody (G3H69), PE, eBioscience™, Invitrogen™

Beschreibung

Description: This G3H69 monoclonal antibody reacts with human Granzyme K. Granzyme K is one of five granzyme serine proteases that have been indentified in humans. These proteins are expressed in the granules of NK cells and cytotoxic T cells, and are critical for the induction of target cell apoptosis through the cleavage of intracellular substrates. Granzyme A and Granzyme K are both tryptases and appear to show overlapping, though not identical, substrate specificity. This functional similarity is believed to account for the minimal decrease in cytotoxicity of Granzyme A-deficient CTLs. Applications Reported: This G3H69 antibody has been reported for use in flow cytometric analysis. Applications Tested: This G3H69 antibody has been pre-diluted and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This may be used at 5 μL (0.06 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser

Granzyme K (GrK) belongs to a family of trypsin-like serine proteases localised in the cytotoxic granules of activated T cells and NK cells. It encodes a 28 kDa serine protease whose gene is located on chromosome 5q11-12 close to the granzyme A-encoding gene. Like granzyme A, it has a trypsin-like specifity cleaving at the basic residues arginine and lysine. Granzyme K triggers rapid cell death independently of caspase activation with single-stranded DNA nicks and is primarily expressed in thymus, lung, spleen and peripheral blood leukocytes.
