試劑空白吸光度是反映試劑質(zhì)量的指標之一,但不能反映試劑質(zhì)量的全部。試劑成份、純度、用量及穩(wěn)定性,才是保證試劑質(zhì)量的關(guān)鍵所在。撫生生物目前市售的一些試劑具有抗干擾作用,主要是通過加入抗干擾物質(zhì)或使用新的色素原以避免內(nèi)源性物質(zhì)的干擾。但值得注意的是:一些試驗項目在消除內(nèi)源性物質(zhì)干擾的同時,會帶來樣品含量真實性的變化。1 試劑空白試劑空白吸光度是反映試劑質(zhì)量的指標之一。
纖維素DE-23
每種試劑都有一定的空白吸光度范圍,試劑空白吸光度的改變往往提示該試劑的變質(zhì);如利用Trinder反應為原理的檢測試劑會因含酚類物質(zhì)被氧化為醌而變?yōu)榧t色。堿性磷酸酶、r一谷氨酰轉(zhuǎn)肽酶、淀粉酶等檢測試劑會因基質(zhì)分解出硝基酚或酚基苯胺而變黃。有些試劑久置后變渾濁。撫生生物這些情況均可使空白吸光度升高。丙氨酸氨基轉(zhuǎn)移酶、天冬氨酸氨基轉(zhuǎn)移酶等負反應,在放置過程中其試劑空白吸光度會因NADH自行氧化為NAD+而下降?!?/span>
