大鼠氨肽酶A(APA)試劑盒
實驗原理：本試劑盒應用雙抗體夾心法測定標本中大鼠氨肽酶A(APA)水平。用純化的大鼠氨肽酶A(APA)抗體包被微孔板，制成固相抗體，往包被單抗的微孔中加入氨肽酶A(APA)，再與HRP標記的氨肽酶A(APA)抗體結合，形成抗體-抗原-酶標抗體復合物，經過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色，并在酸的作用下轉化成zui終的黃色。顏色的深淺和樣品中的氨肽酶A(APA)呈正相關。用酶標儀在450nm波長下測定吸光度（OD值），通過標準曲線計算樣品中大鼠氨肽酶A(APA)的濃度。
Rat Aminopeptidase A(APA) ELISA Kit
Principle of the assay
The kit assay Rat APA level in the sample，use Purified Rat APA to coat microtiter plate wells, make solid-phase antibody, then add APA to wells, Combined APA antibody which With HRP labeled,become antibody - antigen - enzyme-antibody complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of APA in the samples is then determined by comparing the O.D. of the samples to the standard curve.
