Alkaline Phosphatase (ALP) Activity Assay Kit
碱性磷酸酶(ALP)比色法测试盒
规格: | / 50 assays(48 samples) / 100 assays(96 samples) |
价格: | / ¥320 / ¥580 |
货号:E-BC-K091-S
检测仪器及波长: 紫外-可见光分光光度计(520 nm)
样本类型: 动物血清(浆);体液;组织及细胞
检测原理
在pH=10的反应液中,碱性磷酸酶催化磷酸苯二钠水解,生成游离酚和磷酸。酚在碱性溶液中与4-氨基安替吡啉结合,并经铁氰化钾氧化生成红色的醌的衍生物,根据红色的深浅计算酶活的高低。
