【試劑盒名稱】

人骨堿性磷酸酶（BALP）定量檢測(cè)試劑盒（ELISA）

 

【試劑盒用途】

定量檢測(cè)人血清、血漿及相關(guān)液體樣本中骨堿性磷酸酶（BALP）的含量。

 

【檢測(cè)原理】

本試劑盒采用雙抗體一步夾心酶聯(lián)免疫吸附法（ELISA）。將標(biāo)準(zhǔn)品、待測(cè)樣本和酶標(biāo)工作液加入到預(yù)先包被人骨堿性磷酸酶（BALP）抗體的透明酶標(biāo)包被板中，溫育足夠時(shí)間后，洗滌除去未結(jié)合的成分。依次加入顯色劑A、B液，顯色劑（TMB）在辣根過氧化物酶（HRP）催化下轉(zhuǎn)化為藍(lán)色產(chǎn)物，在酸的作用下變成黃色，顏色的深淺與樣品中人骨堿性磷酸酶（BALP）濃度呈正相關(guān)，450nm波長(zhǎng)下測(cè)定OD值，根據(jù)標(biāo)準(zhǔn)品和樣品的OD值，計(jì)算樣本中人骨堿性磷酸酶（BALP）含量。

【操作步驟】

1、準(zhǔn)備：從冰箱取出試劑盒，室溫復(fù)溫平衡30分鐘。

2、配液：用蒸餾水將20倍濃縮洗滌液稀釋成原倍的洗滌液。

3、加標(biāo)準(zhǔn)品和待測(cè)樣本：取足夠數(shù)量的酶標(biāo)包被板，固定于框架上，分別設(shè)置標(biāo)準(zhǔn)品孔、待測(cè)樣本孔和空白對(duì)照孔，記錄各孔位置，在標(biāo)準(zhǔn)品孔中加入標(biāo)準(zhǔn)品50μL；待測(cè)樣本孔中先加入待測(cè)樣本10μL，再加*40μL（即樣本稀釋5倍）；每孔再加入酶標(biāo)工作液100μL；空白對(duì)照孔不加。

4、溫育：37℃水浴鍋或恒溫箱溫育60min。

5、洗板：棄去液體，吸水紙上拍干，每孔加滿洗滌液，靜置1min，甩去洗滌液，吸水紙上拍干，如此重復(fù)洗板5次（也可用洗板機(jī)按說明書操作洗板）。

6、顯色：每孔先加入顯色劑A 液50μL，再加入顯色劑B液 50μL，37℃避光顯色15min。

7、終止：取出酶標(biāo)板，每孔加終止液50μL，終止反應(yīng)（顏色由藍(lán)色立轉(zhuǎn)黃色）。

8、測(cè)定：以空白孔調(diào)零，在終止后15分鐘內(nèi)，用450nm波長(zhǎng)測(cè)量各孔的吸光值（OD值）。

9、計(jì)算：根據(jù)標(biāo)準(zhǔn)品的濃度及對(duì)應(yīng)的OD值，計(jì)算出標(biāo)準(zhǔn)曲線的直線回歸方程，再根據(jù)樣本的OD值，在回歸方程上計(jì)算出對(duì)應(yīng)的樣品濃度，也可以使用各種應(yīng)用軟件來計(jì)算。zui終濃度為實(shí)際測(cè)定濃度乘以稀釋倍數(shù)。

 

【樣本要求】

1、樣本不能含疊氮鈉（NaN₃），因?yàn)?/span>疊氮鈉（NaN₃）是辣根過氧化物酶（HRP）的抑制劑。

2、標(biāo)本采集后盡早進(jìn)行提取，提取按相關(guān)文獻(xiàn)進(jìn)行，提取后應(yīng)盡快進(jìn)行實(shí)驗(yàn)。若不能立即試驗(yàn)，可將標(biāo)本放于-20℃保存，但應(yīng)避免反復(fù)凍融。

3、樣本應(yīng)充分離心，不得有溶血及顆粒。

 

【注意事項(xiàng)】

1、實(shí)驗(yàn)嚴(yán)格按照說明書的操作進(jìn)行，實(shí)驗(yàn)結(jié)果判定必須以酶標(biāo)儀讀數(shù)為準(zhǔn)。

2、酶標(biāo)包被板開封后如未用完，應(yīng)立即裝入密封袋中加干燥劑保存。

3、建議所有的標(biāo)準(zhǔn)品、樣本和空白對(duì)照都做雙份檢測(cè)，取平均值，以減小實(shí)驗(yàn)誤差。

4、若顯色過淺，可適當(dāng)延長(zhǎng)底物溫育時(shí)間。

5、為避免交叉污染，標(biāo)準(zhǔn)品、樣本和空白對(duì)照每加一個(gè)就要更換一次吸頭；酶標(biāo)工作液、*和底物等公共組分，要懸臂加樣，不得碰到微孔；不得重復(fù)使用封板膜。

6、試劑盒保質(zhì)期內(nèi)使用，不同批號(hào)的試劑不得混用。

7、底物B對(duì)光敏感，避免長(zhǎng)時(shí)間暴露于光下。

Human bone alkaline phosphatase （BALP） ELISA Kit instruction

 

Kit name

Human bone alkaline phosphatase （BALP） ELISA Kit

Intended use

The kit is used to assay the content of Human bone alkaline phosphatase （BALP） in Human serum，blood plasma and other related tissue liquid.

Test principle

The kit uses a double-antibody sandwich enzyme-linked immunosorbent assay （ELISA） to assay the level of Human bone alkaline phosphatase （BALP） in samples. Add Human bone alkaline phosphatase （BALP） to pre-coated Human bone alkaline phosphatase （BALP） monoclonal antibody microelisa well, incubation; washing. Add HRP tagged Human bone alkaline phosphatase （BALP） antibodies. After another incubation and washing, remove the unbound enzyme, add Chromogen Solution A and B, the color of the liquid change into blue, and the color finally become yellow at the effect of acid. The depth of the color is positively correlated with concentration of the Human bone alkaline phosphatase （BALP） in samples.

2.         Standard microplate reader

3.         Precision pipettes and Disposable pipette tips

4.         Distilled water

5.         Disposable tubes for sample dilution

6.         Absorbent paper

Assay procedure

1.        Prepare: The kit takeing out from the environment of 2-8℃ should be balanced 30 minutes at less in the room temperature before using.

2.        Diluent: Diluent the 20×wash solution.

3.        Add standard and Sample: Set Standard wells, testing sample wells and blank wells. Add Diluted standard 50μl to standard well; Add Sample dilution 40μl to testing sample well which on Assay plate, then add testing sample 10μl （sample final dilute degree is 5 times）, Add HRP-conjugate reagent 100μl to each well, except the blank well.

4.        Incubation: Incubate 60 minutes at 37 ℃ in incubator.

5.        Wash: Discard Liquid, drying, filling in diluted washing liquid to each well, oscillation for 1 min, discard the washing liquid with absorbent paper Pat dry. Repeat four times, Pat dry.

6.        Add chromogen solution A and B: Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix, incubate for 15 min at 37℃.

7.        Add Stop Solution: Add Stop Solution 50μl to each well, Stop the reaction（the blue color change to yellow immediay）.

8.        Take blank well as zero, measure the optical densit （OD） at 450 nm after adding Stop Solution and within 15 min.

9.        According to standard concentration and the corresponding OD values calculated standard curve linear regression equation, then the OD values according to the sample on the regression equation to calculate the corresponding sample concentration. It should be remembered that the sample has been diluted and its actual concentration should be multiplied by the total dilution.

Specimen requirements

1.      Can’t detect the samples which contain NaN3, because NaN3 inhibits HRP activity of the horseradish peroxidase.

2.      Extract as soon as possible after Specimen collection, Extracted according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can not be tested immediay, specimen can be kept in -20℃ to preserve, but repeated freezing and thawing should be avoided.

3.      The samples shoule be centrifugated dequay and no hemolysis or granule was allowed.

Important notes

1.         The operation should be carried out in strict accordance with instructions and test results must be based on microplate reader to determine readings shall prevail.

2.         If the microelisa stripplate has not used up after open, it should be stored in the sealed bag.

3.         Recommended that all standard materials, test samples are doing double to minish the Experimental error.

4.         Please multiply total dilution times when calculation. 5 times is the best dilute time according to this ELISA Kit design.

5.         If the testing material content in the sample is excessively high, please use Special dilution to dilute certain multiple, then assay.

6.         If the color too shallow, It may be appropriate to extend the substrate incubation time.

7.         Add Sample with sampler each step and proofread its accuracy frequently to avoid the experimental error. In order to avoid cross-contamination, avoid to reusing the suction head and closure plate membrane.

8.         Use the kit in validity, not mix the reagents of different batches.

9.         Chromogen Solution B is light-sensitive, avoid prolonged exposure to light,
