The kit takes out from the refrigeration should be balanced 15-30 minutes in the room temperature, if the coated ELISA plates have not been used up after opening, the plate should be stored in sealed bag.
Washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilution. Washing does not affect the result.
Pipette sample with pipettors each step, and proofread its accuracy frequently, avoids the experimental error. Pipette sample within 5 min, if the number of sample is much, recommend using multichannel pipettor.
If the testing material content is excessively high (The sample OD is higher than the first standard well)?please dilute sample (n-fold).
Adhesive Strip only limits the disposable use to avoid cross-contamination.
The substrate should be preserved evade the light.
Please refer to use instruction strictly. The test result determination must take the microtiter plate reader as a standard.
All samples, washing buffer and each kind of reject should refer to infective material process.
Do not mix reagents with those from other lots.

Target Details : The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions, where they appear to provide protective functions. The cystatin locus on chromosome 20 contains the majority of the type 2 cystatin genes and pseudogenes. This gene is located in the cystatin locus and encodes the most abundant extracellular inhibitor of cysteine proteases, which is found in high concentrations in biological fluids and is expressed in virtually all organs of the body. A mutation in this gene has been associated with amyloid angiopathy. Expression of this protein in vascular wall smooth muscle cells is severely reduced in both atherosclerotic and aneurysmal aortic lesions, establishing its role in vascular disease.
Precision : Intra-assay Precision (Precision within an assay) CV%<15% Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay Precision (Precision between assays) CV%<15% Three samples of known concentration were tested in twenty assays to assess. Linearity : To assess the linearity of the assay, samples were spiked with hig3h concentrations of rat ADP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
Recovery : The recovery of rat Cys-C spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.Sample TypeAverage % RecoveryRange Serum (n=5) 9389-97 EDTA plasma (n=4)9490-98
