Important Note:

By default, qPCR primer pairs are designed to measure the expression level of the splice variant (accession number) you selected for this gene WITHOUT consideration of other possible variants of this gene. If this gene has multiple variants, and you would like to measure the expression levels of one particular variant, multiple variants, or all variants, please contact us for a custom service project at inquiry@genecopoeia.com.

Figure: All-in-One™ qPCR Primer Validated result to CST4. Each All-in-One™ qPCR Primer is experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted gene. A cDNA Pool, containing reverse transcript products of 8 different human tissue total RNA(Liver, Testis,Muscle,Thyroid,Brain,Spleen,Stomach,Small Intestine)),was used as the qPCR validation template. qPCR was performed using 0.2 µM primer with 2XAll-in-One™ qPCR Mix (Catalog#: QP001,QP002,QP004,QP005). Reactions were incubated for 10min. at 95°C, followed by 40 cycles of 95°C for 10 sec.; 60°C, 20 sec. and 72°C, 15sec. using Bio-Rad iQ5™ Instrument. At the end of the last cycle, temperature was increased from 72 to 95°C to produce a melting curve. Panel A: Validated Result for Amplification Curve; Panel B: Validated Result for Melting Curve.

Summary

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. 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 a type 2 salivary cysteine peptidase inhibitor. The protein is an S-type cystatin, based on its high level of expression in saliva, tears and seminal plasma. The specific role in these fluids is unclear but antibacterial and antiviral activity is present, consistent with a protective function.
