Description
The G3H69 monoclonal antibody specifically recognizes Granzyme K which is also known as GRAK, Granzyme-3, Fragmentin-3, Tryptase II (TRYP2), or NK-tryptase-2 (NK-Tryp-2). This granule-associated enzyme is a serine protease that cleaves peptides after the basic residues lysine and arginine. Granzyme K is encoded by GZMK (granzyme K) that belongs to the Granzyme subfamily (Granzymes A, B, H, K, M) within the peptidase S1 family. Granzyme K is expressed in the granules of CD56-bright natural killer (NK) cells, NKT cells, γδ T cells, and cytotoxic CD4+ T cells and CD8+ T cells that can kill pathogen-infected or tumor cells. Granzyme K can activate the SET complex enabling DNase NM23-H1 to make single-stranded nicks in chromosomal DNA which ultimately contribute to target cell death. Granzyme K can also act on Bid and p53 to activate certain cell death pathways. Elevated levels of Granzyme K have been observed in the blood and bodily fluids from individuals under certain infectious or inflammatory conditions.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. An isotype control should be used at the same concentration as the antibody of interest.
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
