Description: Recombinant Human CSTA Protein is produced by E.coli expression system and the target gene encoding Ile2-Phe98 is expressed with a 6His tag at the N-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 100mM NaCl, pH 8.0. Gene Symbol: CSTA Alternative Names: STF1; STFA; Cystatin-A; Cystatin-AS; Stefin-AEntrez Gene (Human): 1475SwissProt (Human): P01040Purity : Greater than 95% as determined by reducing SEC-HPLC and reducing SDS-PAGE.Chemical Structure : MHHHHHHIPG GLSEAKPATP EIQEIVDKVK PQLEEKTNET YGKLEAVQYK TQVVAGTNYY IKVRAGDNKY MHLKVFKSLP GQNEDLVLTG YQVDKNKDDE LTGF Directions for Use : Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control : Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability : Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
