Species : Human
Source : E.coli
Tag : His
Description : The protein encoded by this gene is a proinflammatory cytokine that augments natural killer cell activity in spleen cells, and stimulates interferon gamma production in T-helper type I cells. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2011]
Form : Powder
Bio-activity : Determined by its ability to induce IFN gamma secretion in KG-1 cells. The ED50 for this effect is < 5 ng/mL.
AA Sequence : MYFGKLESKLSVIRNLNDQVLFIDQGNRPLFEDMTDSDCRDNAPRTIFIISMYKDSQPRGMAVTISVKCEKISTLSCENKIISFKEMNPPDNIKDTKSDIIFFQRSVPGHDNKMQFESSSYEGYFLACEKERDLFKLILKKEDELGDRSIMFTVQNED
Endotoxin : Endotoxin level is less than 0.1 EU/μg of the protein, as determined by the LAL test.
Purity : > 98% (by SDS-PAGE)
Applications : SDS-PAGE
Notes : For laboratory research only, not for drug, diagnostic or other use.
Storage : Lyophilized protein should be stored at -20°C. After reconstitution, aliquot and store at -20°C or -80°C for up to one month. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening.
Storage Buffer : PBS (pH 8.0)
Reconstitution : It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min at room temperature to make sure the protein is dissolved completely.
