96 Wells High Sensitive Mouse Secretory Immunoglobulin A ELISA Kit

 

Cat.No E0380Mo

Standard Curve Range: 0.2μg/ml - 60μg/ml

Sensitivity: 0.08μg/ml

*This product is for research use only, not for use in diagnosis procedures. It’s highly recommend to read this instruction entirely before use.

 

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

CV(%) = SD/mean x 100

Intra-Assay: CV<8%

Inter-Assay: CV<10%

 

Assay Principle

This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Mouse sIgA antibody. sIgA present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Mouse sIgA Antibody is added and binds to sIgA in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated sIgA antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Mouse sIgA. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

 

Reagent Preparation

All reagents should be brought to room temperature before use.

Standard Reconstitute the 120μl of the standard (64μg/ml) with 120μl of standard diluent to generate a 32μg/ml standard stock solution. Allow the standard to sit for 15 mins with gentle agitation prior to making dilutions. Prepare duplicate standard points by serially diluting the standard stock solution (32μg/ml) 1:2 with standard diluent to produce 16μg/ml, 8μg/ml, 4μg/ml and 2μg/ml solutions. Standard diluent serves as the zero standard(0 μg/ml). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutions suggested are as follows:

 

32μg/ml Standard No.5 120μl Original Standard + 120μl Standard Diluent
16μg/ml Standard No.4 120μl Standard No.5 + 120μl Standard Diluent
8μg/ml Standard No.3 120μl Standard No.4 + 120μl Standard Diluent
4μg/ml Standard No.2 120μl Standard No.3 + 120μl Standard Diluent
2μg/ml Standard No.1 120μl Standard No.2 + 120μl Standard Diluent

 

Standard Concentration Standard No.5 Standard No.4 Standard No.3 Standard No.2 Standard No.1
64μg/ml 32μg/ml 16μg/ml 8μg/ml 4μg/ml 2μg/ml

 

Wash Buffer Dilute 20ml of Wash Buffer Concentrate 30x into deionized or distilled water to yield 500 ml of 1x Wash Buffer. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved.

 

Summary

1. Prepare all reagents, samples and standards.

2. Add sample and ELISA reagent into each well. Incubate for 1 hour at 37°C.

3. Wash the plate 5 times.

4. Add substrate solution A and B. Incubate for 10 minutes at 37°C.

5. Add stop solution and color develops.

6. Read the OD value within 10 minutes.

 

Calculation of Result

Construct a standard curve by plotting the average OD for each standard on the vertical (Y) axis against the concentration on the horizontal (X) axis and draw a best fit curve through the points on the graph. These calculations can be best performed with computer-based curve-fitting software and the best fit line can be determined by regression analysis.
