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. |
