Cystatins are a superfamily of cysteine proteinase inhibitors found in both plants and animals. They comprise a group of proteinase inhibitors, widely distributed in tissues and body fluids, and form tight complexes with cysteine proteases such as cathepsin B, H, L and S. Cystatin C, a secreted molecule of this family, is of interest from biochemical, medicine and evolutionary points of view. Cystatin C is increased in patients with malignant diseases, and is related to the insufficiency of renal function and appears to be a better marker than creatinine. On the other hand, low levels of cystatin C involve cause the breakdown of the elastic laminae and subsequently, the atherosclerosis and abdominal aortic aneurysm.
Recombinant Human Cystatin C is having a molecular mass of approximately 13kDa.
Sterile Filtered White lyophilized (freeze-dried) powder.
The protein was lyophilized from 20mM NH4HCO3.
It is recommended to reconstitute the lyophilized CST3 Human in sterile 18MΩ-cm H2O at a concentration of 100µg/ml, which can then be further diluted to other aqueous solutions.
Human CST3 although stable at 4°C for 1 week, should be stored at -20°C.
Greater than 96.0%.
