Porcine Strong Sensitivity and Specificity Cathepsin B Sandwich Immunoassay Test Kit With Oem Service
 

Cat.No E0312Po

 

Intended Use

This sandwich kit is for the accurate quantitative detection of Porcine Cathepsin B (also known as Cath-B) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.

 

Assay Principle

This Sandwich Immunoassay Test Kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Porcine Cath-B antibody. Cath-B present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Porcine Cath-B Antibody is added and binds to Cath-B in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated Cath-B 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 Porcine Cath-B. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

 

Standard Curve Range: 0.3ng/ml - 90ng/ml

Sensitivity: 0.147ng/ml

Reagent Preparation

All reagents should be brought to room temperature before use.

Standard Reconstitute the 120μl of the standard (96ng/ml) with 120μl of standard diluent to generate a 48ng/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 (48ng/ml) 1:2 with standard diluent to produce 24ng/ml, 12ng/ml, 6ng/ml and 3ng/ml solutions. Standard diluent serves as the zero standard(0 ng/ml). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutions suggested are as follows:

 

48ng/ml Standard No.5 120μl Original Standard + 120μl Standard Diluent
24ng/ml Standard No.4 120μl Standard No.5 + 120μl Standard Diluent
12ng/ml Standard No.3 120μl Standard No.4 + 120μl Standard Diluent
6ng/ml Standard No.2 120μl Standard No.3 + 120μl Standard Diluent
3ng/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
96ng/ml 48ng/ml 24ng/ml 12ng/ml 6ng/ml 3ng/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.
