L-色氨酸(L-Trp)是哺乳动物细胞蛋白质合成所必需的必需氨基酸,而L-色氨酸向犬尿氨酸(Kyn)的转化途径已被明确确立为先天免疫和适应性免疫的关键调控因子。L-色氨酸分解代谢为犬尿氨酸会通过剥夺免疫细胞的L-色氨酸,并释放具有免疫抑制功能的L-色氨酸降解产物,从而维持免疫抑制微环境。吲哚胺2,3-双加氧酶(IDO1和IDO2)是该途径中的两种限速酶,在多种肿瘤中表达上调,为癌细胞提供了免疫逃逸的途径。
IDO1荧光抑制剂筛选检测试剂盒用于测定吲哚胺 2,3-双加氧酶 1(IDO1)的酶抑制活性。IDO1 荧光抑制剂筛选检测试剂盒操作简便,可在长波长下检测荧光信号,最大程度降低化合物干扰带来的潜在误差。检测过程中,将抑制剂与酶加入含 L-色氨酸(L-Trp)底物的样品中。室温孵育 1 小时后,加入荧光溶液,于 37℃ 下孵育 4 小时。通过在激发波长 400 nm 下激发反应产物,读取 510 nm 处的样品荧光强度来测定酶活性。
