Granulysin is a cytolytic protein present in granules of human natural killer (NK) cells and activated cytotoxic T lymphocytes (CTLs). Granulysin is synthesized as a 15 kD precursor, which is then cleaved at both the amino- and carboxy-termini into a 9 kD activated form.
The 9 kD granulysin is released into the intercellular space between target and effector cells via a granule exocytosis pathway. The 9 kD granulysin is a chemoattractant for T lymphocytes, monocytes, and other inflammatory cells and activates the expression of a number of cytokines, including RANTES, MCP-1, MCP-3, MIP-1α, IL-1, IL-6, IL-10 and IFN-α.
High serum levels of granulysin are associated with cytotoxic T cell and NK cell activity, and may thus represent a soluble biomarker for host-cellular immune responses. Serum granulysin has also been proposed as a biomarker for the Th1/Th2 balance. At the cellular level, granulysin may serve as a favorable prognostic marker for certain types of cancer.
- Antibody Type
- Host Species
- Recombinant 9 kD granulysin
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
- The antibody was purified by affinity chromatography and conjugated with biotin under optimal conditions.
- 0.5 mg/ml
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
ELISA Detection - Quality tested
Neut, IP - Reported in the literature
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. A concentration of 1 µg/µl of the detection antibody was utilized to gernerate the example standard curve. It is recommended that the end-user titrate each lot of reagents for optimal performance.
- Application Notes
ELISA Detection: To measure human granulysin, this antibody can be used as a detection antibody in sandwich ELISA format and paired with the purified DH2 antibody (Cat. No. 348007) as the capture antibody.
Additional reported applications (for the relevant formats) include: neutralization1 and immunoprecipitation1.
Note: For testing human granulysin in serum, plasma or cell culture supernatant, LEGEND MAX™ Human Granulysin ELISA Kit with Pre-coated Plates (Cat. No. 438007 & 438008) are specially developed and recommended.
