生物活性

SK48-E26 is a human interleukin-1β (IL-1β) inhibitor, with a IC50 of 400 pM against human IL-1β, a IC50 of 185 pM against cynomolgus monkey IL-1β, and a Ka value ranging from 0.048 nM to 3 nM for human IL-1β. SK48-E26 binds to the conformational epitope of human IL-1β spanning amino acid residues 95-101, and blocks the biological activity of IL-1β. SK48-E26 can be used in research related to IL-1β-mediated inflammatory diseases and osteoarthritis[1][2].

SK48-E26 可在 ELISA 实验中有效捕获人重组 IL-1β,实现对 hrIL-1β 的检测,最低检测浓度可达 0.1 至 0.2 ng/mL,且对 IL-1β 浓度呈线性响应[1]
SK48-E26 可在基于 EL-4 细胞的生物分析中特异性中和人重组 IL-1β 的活性,结合 hrIL-1β 上覆盖 95-101 位氨基酸的构象表位,且与 IL-1β 的亲和力为 0.5 至 3 nM[1]
SK48-E26 Fab 片段重链 CDR3 区域的突变可提高其对人重组 IL-1β 的亲和力,其中 V120T/R121K 突变体的亲和力较野生型 SK48-E26 Fab 提高 9.79 倍[1]
SK48-E26 (10-200 nM) 可与人 IL-1β 结合,其平衡解离常数为 242 pM[2]
SK48-E26 (1×10-15-1×10-7 M; 1 h pre-incubation with IL-1β, 16-20 h incubation with cells) 可在 MRC-5 细胞中中和人源 IL-1β (IC50 为 400 pM) 以及食蟹猴 IL-1 β(IC50 为 185 pM)[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
