Active Granulysin (GNLY)
1. Splice variants: Alternative splicing may create different sized proteins from the same gene.
2. Relative charge: The composition of amino acids may affects the charge of the protein.
3. Post-translational modification: Phosphorylation, glycosylation, methylation etc.
4. Post-translation cleavage: Many proteins are synthesized as pro-proteins, and then cleaved to give the active form.
5. Polymerization of the target protein: Dimerization, multimerization etc.
Avoid repeated freeze/thaw cycles.
Store at 2-8 degree C for one month.
Aliquot and store at -80 degree C for 12 months.
Stability Test:
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

Bioactivity
(Granulysin (GNLY) is a member of the saposin-like protein (SAPLIP) family of membrane disrupting proteins. Granulysin is expressed in granules of natural killer and activated cytotoxic T cells. It exhibits cytolytic activity against intracellular or extracellular microbes and also tumors, either alone or in synergy with perforin. Human granulysin has structural similarity and 30 - 40% aa identity to granulysins and NK-lysins of other mammals such as bovine, porcine and canine; similar peptides in rodents have not been identified. The 15 kDa unglycosylated protein contains five helical domains; helix 2 and 3 contain 9 arginines and one cysteine critical for activity. The activity of GNLY is usually measured by a cell apoptosis assay using Jurkat cells. Jurkat cells were seeded into triplicate wells of 96-well plates at a density of 8,000 cells/well with 5% serum standard 1640 which contains various concentrations of recombinant human GM-CSF.After incubated for 3 days, cells were observed by inverted microscope and cell proliferation was measured by Cell Counting Kit-8 (CCK-8). Briefly, 10 ul of CCK-8 solution was added to each well of the plate, then the absorbance at 450 nm was measured using a microplate reader after incubating the plate for 2-4 hours at 37 degree C. Apoptosis of Jurkat cells after incubation with GNLY for 3 days observed by inverted microscope was shown in Figure 1. Cell viability was assessed by CCK-8 (Cell Counting Kit-8 ) assay after incubation with recombinant human GNLY for 3 days. The result was shown in Figure 2. It was obvious that GNLY significantly decreased cell viability of Jurkat cells. The ED50 is 0.84 ug/ml.Figure 1. Inhibition of Jurkat cells proliferation after stimulated with GNLY(A) Jurkat cells cultured in 1640, stimulated with 1.25 ug/mL GNLY for 72h;(B) Unstimulated Jurkat cells cultured in 1640 for 72h.)

Product Notes
The GNLY gnly (Catalog #AAA153093) is an Active Protein and is intended for research purposes only. The product is available for immediate purchase. The Active Granulysin (GNLY) reacts with Homo sapiens (Human) and may cross-react with other species as described in the data sheet. AAA Biotech's Granulysin (GNLY) can be used in a range of immunoassay formats including, but not limited to, Activity Assay, Cell Culture. Researchers should empirically determine the suitability of the GNLY gnly for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Granulysin (GNLY), Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
