产品名称Recombinant Human 4-1BB Receptor/TNFRSF9

来源种属Escherichia coli.

纯化> 97 % by SDS-PAGE and HPLC analyses.

生物活性Fully biologically active when compared to standard. The biological activity is determined by its inhibitory effect of IL-8 production using human peripheral blood mononuclear cells. About 90 % of inibition was seen using a concentration of 1 μg for both 4-1BB Ligand and 4-1BB Receptor.

内毒素Less than 1 EU/ug of rHu4-1BB Receptor as determined by LAL method.
