Background: Human Cystatin A (CSTA) is a member of family 1 of the cystatin superfamily; which is characterized by lacking of disulphide bonds an carbohydrates. Cystatin A is an intracellular inhibitor regulating the activities of cysteine proteases of the papain family such as Cathepsins B; H and L. Cystatin A is also implicated in a number of disease states. Due to altered proteolytic state in cancer progression; Cystatin A may play a role in the proteolytic pathways.
Sequence: Ile2-Phe98
Purity: > 95 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 100mM NaCl, pH 8.0.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
