Invitrogen™ Human Cystatin 9 Control Fragment Recombinant Protein

Product Code. 30209166

Brand: Invitrogen™ RP88587

Description

Recombinant Protein

Highest antigen sequence indentity to the following orthologs: Mouse (39%), Rat (39%). This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-56080 (PA5-56080. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

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 a secreted protein that may play a role in hematopoietic differentiation or inflammation.
