小鼠MMP-2 ELISA試劑盒說明書

INTENDED USE AND TEST PRINCIPLE

This MMP-2 ELISA kit is intended Laboratory for Research use only and is not for use in diagnostic or therapeutic procedures. The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of MMP-2 in the sample, this MMP-2 ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus MMP-2 concentration. The concentration of MMP-2 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

1.  從室溫平衡20min后的鋁箔袋中取出所需板條，剩余板條用自封袋密封放回4℃。

2.  設置標準品孔和樣本孔，標準品孔各加不同濃度的標準品50μ嘗；

3.  樣本孔中加入待測樣本50μ嘗；空白孔不加。

4.  除空白孔外，標準品孔和樣本孔中每孔加入辣根過氧化物酶（HRP）標記的檢測抗體100μ嘗，用封板膜封住反應孔，37℃水浴鍋或恒溫箱溫育60min。

5.  棄去液體，吸水紙上拍干，每孔加滿洗滌液（350μ嘗），靜置1min，甩去洗滌液，吸水紙上拍干，如此重復洗板5次（也可用洗板機洗板）。

6.  每孔加入底物A、B各50μ嘗，37℃避光孵育15min。

7.  每孔加入終止液50μ嘗，15min內，在450nm波長處測定各孔的OD值。

實驗結果計算

以所測標準品的翱頓值為橫坐標，標準品的濃度值為縱坐標，在坐標紙上或用相關軟件繪制標準曲線，并得到直線回歸方程，將樣品的翱頓值代入方程，計算出樣品的濃度。

ASSAY PROCEDURE

1.  Prepare all reagents before starting assay procedure. It is recommended that all Standards and Samples be added in duplicate to the Microtiter plate.

2.  Add 50μl of Standard or Sample to the appropriate wells. Blank well doesn’t add anyting.

3.  Add 100μl of Enzymeconjugate to standard wells and sample wells except the blank well, cover with an adhesive strip and incubate for 60 minutes at 37°C.

4.  Wash the Microtiter Plate 4 times.

Manual Washing - Remove incubation mixture by aspirating contents of the plate into a sink or proper waste container. Using a squirt bottle, fill each well completely with Wash Solution (1X), then aspirate contents of the plate into a sink or proper waste container. Repeat this procedure for a total of four times. After final wash, invert plate, and blot dry by hitting plate onto absorbent paper or paper towels until no moisture appears. Note: Hold the sides of the plate frame firmly when washing the plate to assure that all strips remain securely in frame.

Automated Washing - Aspirate all wells, then wash plates four times using Wash Buffer (1X). Always adjust your washer to aspirate as much liquid as possible and set fill volume at 350μ嘗/well/wash. After final wash, invert plate, and blot dry by hitting plate onto absorbent paper or paper towels until no moisture appears.

5.  Add Substrate A 50μl and Substrate B 50μl to each well. Gently mix and incubate for 15 minutes at 37°頒. Protect from light.

6.  Add 50μl Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not appear uniform, gently tap the plate to ensure thorough mixing.

7.  Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.
