Together with Cystatins S and SA, it is produced by the salivary gland and secreted largely in the submandibular\/sublingual saliva. Cystatin-SN inhibits members of the Papain family including Cathepsins B, C, H and L.\u003c\/p\u003e\n\n\u003cp\u003eSequence: Trp21-Ser141\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2 μm filtered solution of 20mM MES, 150mM NaCl, pH 5.5.\u003cbr\u003e\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\u003cbr\u003e\nPlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: Please refer to the printed manual for detailed information.\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 15.4 kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 17 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃.
