Description: Recombinant Human REG1A Protein is produced by Mammalian expression system and the target gene encoding Gln23-Asn166 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.2. Gene Symbol: REG1A Alternative Names: PSPS; PSPS1; REG; Lithostathine-1-alpha; Islet cells regeneration factor; ICRF; Islet of Langerhans regenerating protein; REG; Pancreatic stone protein; PSP; Pancreatic thread protein; PTP; Regenerating islet-derived protein 1-alpha; REG-1-alpha; Regenerating protein I alphaEntrez Gene (Human): 5967SwissProt (Human): P05451Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : QEAQTELPQA RISCPEGTNA YRSYCYYFNE DRETWVDADL YCQNMNSGNL VSVLTQAEGA FVASLIKESG TDDFNVWIGL HDPKKNRRWH WSSGSLVSYK SWGIGAPSSV NPGYCVSLTS STGFQKWKDV PCEDKFSFVC KFKNVDHHHH HH 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.
