USAGE
胰岛素样生长因子结合蛋白2(IGFBP2)重组蛋白Reconstitute in sterile PBS, pH7.2-pH7.4.
STORAGE AND STABILITY
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

基因组水平上对某一刺激或疾病进行检测。例如,Bittner M等对8150个基因进行检测。发现了皮肤黑素瘤的亚种。Zhang W等发现类胰岛素生长因子结合蛋白2(IGFBP2)在神经胶质瘤和恶性胶质瘤的后期阶段表达量很大,且差异很大。Gu J等对患有ankylosing spondylitis(AS)、类风湿性关节炎(RA)和正常人的外周血单核细胞(PBMC)的基因表达进行分析后发现,患有AS的病人与患有RA的病人的PBMC表达模式差异很大,且极不正常。Tanaka F等用芯片分析后发现了在FAO
830 Da.MTF-1 还未见报道,其作用机制还需进一步研究 [31,32] . Amaar 与其同事发现 29 KDa 的胰岛素样生长因子结合蛋白质 -5(Insulin-like grow binding protein,IGFBP) ,是一个重要的骨成形调节因子,其本身也是一种不依赖胰岛素样生长因子 (insulin-like growth factor,IGF) 的生长因子 . 而 IGFBP-5 有一段核内定位序列,因而推测他可能可以进入核内,并与核蛋白结合从而影响骨成形基因
