Pyrophosphate (PPi) Assay Kit(Fluorometric/Colorimetric)

無機焦磷酸鹽(Inorganic pyrophosphate, diphosphate二磷酸鹽 ,焦磷酸pyrophosphoric acid或PPi)是在許多生化反應期間形成或作為底物所需的小分子。產生PPi的酶促反應包括ATP水解 (ATP hydrolysis) ,DNA和RNA聚合(DNA and RNA polymerization),環AMP形成 (cyclic AMP formation)和脂肪酸 (fatty acids) 的酶促活化以形成它們的CoA酯 (CoA esters)。相反,使用PPi的酶可以包括環化酶 (cyclases),水解酶 ( hydrolases ) 和連接酶 (ligases)。在骨代謝 (bone metabolism),腎結石疾病 ( renal stone disease) 和某些類型的關節炎 ( arthritis) 的研究中,血漿 (plasma),血清(serum)和其他生物液體 (biologic fluids)測量無機焦磷酸鹽(PPi)是重要的。 BioVision的焦磷酸鹽(Pyrophosphate (PPi) Assay Kit , K568)分析試劑盒,為生物材料中游離無機焦磷酸鹽水平的測定提供了一種快速,方便和超靈敏的方法。生物過程中產生的PPi通過一系列利用專有酶混合物和探針的反應進行檢測,產生穩定的產物,可以通過比色或螢光讀數進行定量。產生的螢光(Ex / Em = 535/587 nm)或者顏色(OD:570 nm)強度與焦磷酸鹽的濃度成正比,可以進行精確的測量。單體無機磷酸鹽(Pi)不干擾測定。檢測方法提供了一種簡單的方法,適用於各種生物樣品,並且可以以方便的微量滴定板 ( microtiter-plate format) 格式進行。該試劑盒分別提供了足夠的試劑, 可用於100個螢光測定或50個比色測定。該試劑盒可在血漿和血清樣品中檢測,最低靈敏度為1.8μM的PPi。
