特點
First assay in the market that measures CβS activity in biological samples
產品描述:胱硫醚β合酶(EC 4.2.1.22,CβS)是一種PLP依賴性酶,當使用半胱氨酸和高半胱氨酸作為底物時,其催化H2S和胱硫醚的形成。已知其在人類硫代謝中作用,CβS的基因中的突變可導致血漿中高濃度的高半胱氨酸。同型半胱氨酸的循環濃度升高會導致遺傳性疾病,包括高半胱氨酸血症和唐氏綜合徵。 Homocysteinuria是一種常染色體隱性遺傳疾病,臨床表現包括智力低下,血栓栓塞和結締組織缺陷。硫化氫,CβS產物是重要的氣體介質,如一氧化氮,對哺乳動物的免疫,神經,心血管和肺系統有顯著的影響。 BioVision的胱硫醚β合酶試劑盒利用半胱氨酸和高半胱氨酸作為底物來產生硫化氫。硫化氫與熒光探針的疊氮基官能團反應,產生熒光氨基(Ex / Em = 368 / 460nm)。該測定法是高度敏感的,具有簡單易行的方案,並且可以檢測到低至1.45mU的CβS活性。
