Recombinant Human Tumor Necrosis Factor β/TNFβ (C181)

目录 规格 价格
【TNF-β产品说明】:
Recombinant Human Tumor Necrosis Factor beta is produced by our E.coli expression system and the target gene encoding Leu35-Leu205 is expressed.
【TNF-β质量控制】:
Measured in a cytotoxicity assay using L‑929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D.
The ED50 for this effect is typically 23 pg/mL.
Greater than 95% as determined by reducing SDS-PAGE.
【TNF-β制剂】:
Lyophilized
【TNF-β保存】:
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.
【TNF-β复溶】:
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in ddH2O.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
【关于TNF-β】:
Tumor Necrosis Factor β (TNF-β) is a secreted protein belonging to the tumor necrosis factor family. TNF-β binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR and TNFRSF14/HVEM in homotrimeric form, binds to TNFRSF3/LTBR in heterotrimeric form with LTB. TNF-β forms heterotrimers with lymphotoxin-beta, which anchors TNF-β to the cell surface. TNF-β mediates the inflammatory, immunostimulatory, and antiviral response, involves in the formation of second lymphoid organs during development, has a role in apoptosis. TNF-β is produced by lymphocytes and cytotoxic for a variety of tumor cells in vitro and in vivo.
