人髓過氧化物酶(MPO)ELISA檢測試劑盒操作步驟
實驗開始前,請?zhí)崆芭渲煤盟性噭?,試劑或樣品稀釋時,均需混勻,混勻時盡量避免起泡。每次檢測都應(yīng)該做標(biāo)準(zhǔn)曲線。如樣品濃度過高時,用樣品稀釋液進行稀釋,以使樣品符合試劑盒的檢測范圍。
1. 加樣:分別設(shè)空白孔、標(biāo)準(zhǔn)孔、待測樣品孔??瞻卓准訕悠废♂屢?00μl,余孔分別加標(biāo)準(zhǔn)品或待測樣品100μl,注意不要有氣泡,加樣將樣品加于酶標(biāo)板孔底部,盡量不觸及孔壁,輕輕晃動混勻,酶標(biāo)板加上蓋或覆膜,37℃反應(yīng)120分鐘。
為保證實驗結(jié)果有效性,每次實驗請使用新的標(biāo)準(zhǔn)品溶液。
2.棄去液體,甩干,不用洗滌。每孔加生物素標(biāo)記抗體工作液 100μl(取1μl生物素標(biāo)記抗體加99μl生物素標(biāo)記抗體稀釋液的比例配制,輕輕混勻,在使用前一小時內(nèi)配制),37℃,60分鐘。
3. 溫育60分鐘后,棄去孔內(nèi)液體,甩干,洗板3次,每次浸泡1-2分鐘,350μl/每孔,甩干。
4.每孔加辣根過氧化物酶標(biāo)記親和素工作液(同生物素標(biāo)記抗體工作液) 100μl,37℃,60分鐘。
5. 溫育60分鐘后,棄去孔內(nèi)液體,甩干,洗板5次,每次浸泡1-2分鐘,350μl/每孔,甩干。
6. 依序每孔加底物溶液90μl,37℃避光顯色(30分鐘內(nèi),此時肉眼可見標(biāo)準(zhǔn)品的前3-4孔有明顯的梯度藍色,后3-4孔梯度不明顯,即可終止)。
7.依序每孔加終止溶液50μl,終止反應(yīng)(此時藍色立轉(zhuǎn)黃色)。終止液的加入順序應(yīng)盡量與底物液的加入順序相同。為了保證實驗結(jié)果的準(zhǔn)確性,底物反應(yīng)時間到后應(yīng)盡快加入終止液。
8. 用酶聯(lián)儀在450nm波長依序測量各孔的光密度(OD值)。 在加終止液后15分鐘以內(nèi)進行檢測。
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 doesn’t add anyting.
4. Add 100μl 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 10.0 pg/ml
6.Standard curve
