Description：Recombinant Human SPINK1 Protein is produced by Mammalian expression system and the target gene encoding Asp24-Cys79 is expressed with a 6His tag at the C-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM MES, 150mM NaCl, 2mM CaCl2, 1mM DTT, 0.05% Brij35, 10% Glycerol, pH 6.0.Gene Symbol：SPINK1Alternative Names：PSTI; Pancreatic secretory trypsin inhibitor; Serine protease inhibitor Kazal-type 1; Tumor-associated trypsin inhibitor; TATI Entrez Gene (Human)： 6690; SwissProt (Human)： P00995; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：DSLGREAKCY NELNGCTKIY DPVCGTDGNT YPNECVLCFE NRKRQTSILI QKSGPCVDHH HHHHDirections 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：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
