used within 1 month.
* 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 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:
| 12ng/ml | Standard No.5 | 120μl Original Standard + 120μl Standard Diluent |
| 6ng/ml | Standard No.4 | 120μl Standard No.5 + 120μl Standard Diluent |
| 3ng/ml | Standard No.3 | 120μl Standard No.4 + 120μl Standard Diluent |
| 1.5ng/ml | Standard No.2 | 120μl Standard No.3 + 120μl Standard Diluent |
| 0.75ng/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 |
| 24ng/ml | 12ng/ml | 6ng/ml | 3ng/ml | 1.5ng/ml | 0.75ng/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.
