* 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%
 
Intended Use
This sandwich kit is for the accurate quantitative detection of Human Cystatin C (also known as Cys-C) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.
 
Reagent Provided

 
Reagent Preparation
All reagents should be brought to room temperature before use.
Standard Reconstitute the 120μl of the standard (24ng/ml) with 120μl of standard diluent to generate a 12ng/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 (12ng/ml) 1:2 with standard diluent to produce 6ng/ml, 3ng/ml, 1.5ng/ml and 0.75ng/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:
 

 
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.
