C-Reactive 蛋白
品牌:MedChemExpress (MCE)
货号:HY-P74221
纯度:Greater than 90% as determined by reducing SDS-PAGE.
运输条件:用干冰运输。
产品活性:C-Reactive 蛋白是一种急性期蛋白,是炎症细胞因子的标志物,帮助补体结合和巨噬细胞的吞噬作用,来源于肝脏。C-Reactive 蛋白也是第一个被识别的模式识别受体 (PRR)。C-Reactive 蛋白与首次缺血性中风的风险显著相关,尤其是在小血管病。C-Reactive 蛋白 (Human) 是一种无标签的重组蛋白,由 224 个氨基酸组成,在 HEK293 细胞中表达。
研究背景:C-Reactive 蛋白 (Human) 是一种环状 (环形) 五聚体蛋白,存在于血浆中,其循环浓度会因炎症而升高。C-Reactive 蛋白 (Human)与死细胞或衰亡细胞表面表达的溶血磷脂酰胆碱(以及某些类型的细菌)结合,以通过结合 C1q 激活经典补体途径[2]。 C-Reactive 蛋白 (Human) 是由肝脏合成的,响应巨噬细胞,T 细胞和脂肪细胞释放的因子,它是五聚素家族蛋白的一员,含有信号肽[3]。 C-Reactive 蛋白 (Human) 能够与细菌细胞表面表达的磷脂酰胆碱结合,如肺炎球菌,这会激活补体系统,促进巨噬细胞的吞噬作用,从而清除坏死和凋亡的细胞及细菌[4,5]。 C-Reactive 蛋白 (Human) 结合微生物上的磷脂酰胆碱,这有助于补体结合外来损伤细胞,并增强巨噬细胞的吞噬作用。C-Reactive 蛋白 (Human) 作为对抗感染的早期防御系统在先天免疫中发挥重要作用[4] C-Reactive 蛋白 (Human) 是一种史前抗体,会与 Fc-gamma 受体 IIa 结合[6]。
