试剂的准备
20×洗涤缓冲液的稀释:蒸馏水按1:20稀释,即1份的20×洗涤缓冲液加19份的蒸馏水。
洗板方法
  1. 手工洗板:甩尽孔内液体,每孔加满洗涤液,静置1min后甩尽孔内液体,在吸水纸上拍干,如此洗板5次。
  2. 自动洗板机:每孔注入洗液350μL,浸泡1min,洗板5次。
操作步骤
  1. 从室温平衡60min后的铝箔袋中取出所需板条,剩余板条用自封袋密封放回4℃。
  2. 设置标准品孔和样本孔,标准品孔各加不同浓度的标准品50μL;
  3. 待测样本孔先加待测样本10μL,再加样本稀释液40μL;
  4. 随后标准品孔和样本孔中每孔加入辣根过氧化物酶(HRP)标记的检测抗体100μL,用封板膜封住反应孔,37℃水浴锅或恒温箱温育60min。
  5. 弃去液体,吸水纸上拍干,每孔加满洗涤液,静置1min,甩去洗涤液,吸水纸上拍干,如此重复洗板5次(也可用洗板机洗板)。
  6. 每孔加入底物A、B各50μL,37℃避光孵育15min。
  7. 每孔加入终止液50μL,15min内,在450nm波长处测定各孔的OD值。
结果判断
绘制标准曲线:在Excel工作表中,以标准品浓度作横坐标,对应OD值作纵坐标,绘制出标准品线性回归曲线,按曲线方程计算各样本浓度值。

◇组织标本:
切割标本后,称取重量。加入一定量的PBS ,缓冲液中可加入1 μg/L 蛋白酶抑制剂或50U/ml 的Aprotinin (抑肽酶)。用手工或匀浆器将标本匀浆充分。离心20 分钟左右(2000-3000 转/ 分)。仔细收集上清置于-20 度或- 70 度保存,如有必要,可以将样品浓缩干燥。分装后一份待检测,其余冷冻备用。

Reagent preparation
20×wash solution:Dilute with Distilled or deionized water 1:20.
Assay procedure
1. Prepare all reagents before starting assay procedure. It is recommended that all Standards and Samples be added in duplicate to the Microelisa Stripplate.
2. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.
3. Add Sample: Add testing sample 10μl Then add sample diluent 40μl to testing sample well; Blank well doesnt add anyting.
4. Add 10l of HRP-conjugate reagent to each well, cover with an adhesive strip and incubate for 60 minutes at 37°C.
5. Aspirate each well and wash, repeating the process four times for a total of five washes. Wash by filling each well with Wash Solution (400μl) using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate and blot it against clean paper towels.
6. Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix and incubate for 15 minutes at 37°C. Protect from light.
7. 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.
8. Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.
Calculation of results
  1. This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. (450 nm) obtained for each of the six standard concentrations on the vertical (Y) axis versus the corresponding concentration on the horizontal (X) axis.
  2. First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software.
  3. To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration.
  4. Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.
  5. The sensitivity by this assay is 0.1 nmol/L.
