胰岛素样生长因子结合蛋白(IGFBPs)是一类与IGFs共同进化的同源蛋白,它们不仅作为可溶性IGFs的穿梭分子,而且对IGF信号系统具有一定的调控作用。IGFBPs与IGF的物理结合影响生长因子的生物利用度及其在细胞外环境中的浓度和分布。IGFBPs似乎也有独立于IGFs的生物学活性。目前已经描述了7种IGFBPs,它们在组织分布、半衰期以及调节IGF与其受体的相互作用方面各不相同。IGFBP1受到胰岛素产生的负调控。IGFBP1基因在胎儿肝脏发育过程中以及营养变化和糖尿病的反应中高水平表达。IGFBP2可能作为伴侣蛋白,将IGFs护送到其靶组织,在包括胎儿眼睛和胎儿大脑在内的多种人体组织中表达。IGFBP3是最丰富的IGFBP,与大约80%的血清IGFs形成复合物。IGFBP3和IGFBP4均由皮肤成纤维细胞在切口损伤后释放。IGFBP5由肌细胞分泌,可能在肌肉分化中发挥关键作用。IGFBP6与其他IGFBPs的不同之处在于它对IGF-II具有最高的亲和力。糖基化人IGFBP6表达于中国仓鼠卵巢(CHO)细胞,而非糖基化重组人IGFBP-6表达于大肠杆菌。IGFBP7是一种分泌蛋白,它以相对较低的亲和力与IGF-I和IGF-II结合,刺激前列环素的产生,也可能作为生长抑制因子发挥作用。

Most westerns for IGFBP2 show it at ~36kDa. In the posted western IGFBP2 is around 70kDa, why is that?

Asked by: SophieP
Thank you for your question. For the Western blot data you are referring to, this is not representative of the endogenous molecular weight for IGFBP2. In lane B, a truncated IGFBP2 protein is fused to the Fc portion of a human IgG molecule before transfecting into CHO-K1 cells. We will revise our data legend to make this more clear that this is representative of the antibody detecting a transfected fusion-protein, IGFBP2-hIgGFc.

How much sample do you recommend loading on the gel for Western blot detection using IGFBP2 (1F6F6): sc-130070?

Asked by: Randy McDonald
We recommend loading 40–60 µg whole cell lysate, 10–20 µg nuclear extract, 5-10 µg transfected lysate, or 10–20 ng purified protein per lane. A link to our complete Western blotting protocol is provided here for your reference: https://www.scbt.com/scbt/resources/protocols/western-immuno-blotting
