小鼠肌动蛋白样蛋白6B（Actl6B）ELISA试剂盒2022采购推荐检测原理

ELISA实验原理是酶分子与抗体或抗抗体分子共价结合,此种结合不会改变抗体的免疫学特性,也不影响酶的生物学活性。 酶标记抗体可与吸附在固相载体上的抗原或抗体发生特结合。滴加底物溶液后,底物可在酶作用下使其所含的供氢体由无色的还原型变成有色氧化型,出现颜色反应。 因此,可通过底物的颜色反应来判定有无相应的免疫反应,颜色反应的深浅与标本中相应抗体或抗原的量呈正比。此种显色反应可通过ELISA检测仪进行定量测定，这样就将酶化学反应的敏感性和抗原抗体反应的特结合起来，使ELISA方法成为一种既特异又敏感的检测方法。

Rat CXCL9 ELISA Kit instruction

Intended use

This CXCL9 ELISA kit is intended Laboratory for Research use only ａnd is not for use in diagnostic or therapeutic procedures.The S 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 CXCL9 in the sample, this CXCL9 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 CXCL9 concentration. The concentration of CXCL9 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Sample collection ａnd storages

Serum - Use a serum separator tube ａnd allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximately 3000×g. Remove serum ａnd assay immediately or aliquot ａnd store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cycles

Plasma - Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 30 minutes at 3000×g at 2-8℃ within 30 minutes of collection. Store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Cell culture supernates ａnd other biological fluids - Remove particulates by centrifugation ａnd assay immediately or aliquot ａnd store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Note:  The samples shoule be centrifugated dequately ａnd no hemolysis or granule was allowed.

Materials required but not supplied

1.  Standard microplate reader(450nm)

2.  Precision pipettes ａnd Disposable pipette tips.

3.  37 ℃ incubator

Precautions

1.  Do not substitute reagents from one kit to another. Standard, conjugate and microplates are matched for optimal performance. Use only the reagents supplied by manufacturer.

2.  Do not remove microplate from the storage bag until needed. Unused strips should be stored at 2-8°C in their pouch with the desiccant provided.

3.  Mix all reagents before using.

Remove all kit reagents from refrigerator ａnd allow them to reach room temperature ( 20-25°C)

Materials supplied

Note: Standard (S0 → S5) concentration was followed by:0,125,250,500,1000,2000 pg/ml

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 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 S 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 erage 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 pg/ml

6. Standard curve
