Description：Recombinant Human CTSL Protein is produced by mammalian expression system in human cells. The target protein is expressed with the full length sequence of Human Cathepsin L fused with a polyhistidine tag at the C-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM HAc-NaAc, 150mM NaCl, pH 4.5.Gene Symbol：CTSLAlternative Names：CTSL1; Cathepsin L1; Cathepsin L; Major excreted protein; MEP Entrez Gene (Human)： 1514; SwissProt (Human)： P07711; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：TLTFDHSLEA QWTKWKAMHN RLYGMNEEGW RRAVWEKNVK MIELHNQEYR EGKHSFTMAM NAFGDMTSEE FRQVMNGFQN RKPRKGKVFQ EPLFYEAPRS VDWREKGYVT PVKNQGQCGS CWAFSATGAL EGQMFRKTGR LISLSEQNLV DCSGPQGNEG CNGGLMDYAF QYVQDNGGLD SEESYPYEAT EESCKYNPKY SVANDTGFVD IPKQEKALMK AVATVGPISV AIDAGHESFL FYKEGIYFEP DCSSEDMDHG VLVVGYGFES TESDNNKYWL VKNSWGEEWG MGGYVKMAKD RRNHCGIASA ASYPTVVDHH 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.
