Goat Anti-Mouse Cystatin C antibody for ELISA(Det), WB. Cystatin C is a member of family 2 of the cystatin superfamily. It is involved in processes such as tumor invasion and metastasis, inflammation and some neurological diseases. It inhibits many cysteine proteases such as papain and cathepsins B, H, K, L and S. All mouse tissues analyzed expressed Cystatin C, with relative levels similar to those of rat and human tissues. For all three species, brain and liver had the highest and lowest levels of Cystatin C, respectively, whereas kidney, spleen and muscle had the levels in between. The high degree of similarity in distribution and functional properties for mouse, rat and human Cystatin C indicates that a murine model should be relevant for studies of the human disease, hereditary Cystatin C amyloid angiopathy.
