Free Fatty Acids (NEFA/FFA) Fluorometric Assay Kit
游离脂肪酸(NEFA/FFA)荧光测定试剂盒
规格: | / 48T(32 samples) / 96T(80 samples) |
价格: | / ¥4180 / ¥6850 |
货号:E-BC-F039
检测仪器及波长: 荧光酶标仪(激发波长535 nm,发射波长590 nm)
样本类型: 血清;血浆;动物组织和细胞样本
检测原理
游离脂肪酸在酰基合成酶的作用下生成酰基辅酶A,酰基辅酶A在酰基氧化酶的氧化作用下生成过氧化氢。过氧化氢在酶和探针的存在下反应,产生的荧光物质在激发波长535 nm和发射波长590 nm处的荧光强度与游离脂肪酸浓度成正比。
