Description: Recombinant Human GC Protein is produced by Mammalian expression system and the target gene encoding Leu17-Leu474 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: GC Alternative Names: Vitamin D-binding protein; DBP; VDB; Gc-globulin; Group-specific componentEntrez Gene (Human): 2638SwissProt (Human): P02774Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : LERGRDYEKN KVCKEFSHLG KEDFTSLSLV LYSRKFPSGT FEQVSQLVKE VVSLTEACCA EGADPDCYDT RTSALSAKSC ESNSPFPVHP GTAECCTKEG LERKLCMAAL KHQPQEFPTY VEPTNDEICE AFRKDPKEYA NQFMWEYSTN YGQAPLSLLV SYTKSYLSMV GSCCTSASPT VCFLKERLQL KHLSLLTTLS NRVCSQYAAY GEKKSRLSNL IKLAQKVPTA DLEDVLPLAE DITNILSKCC ESASEDCMAK ELPEHTVKLC DNLSTKNSKF EDCCQEKTAM DVFVCTYFMP AAQLPELPDV ELPTNKDVCD PGNTKVMDKY TFELSRRTHL PEVFLSKVLE PTLKSLGECC DVEDSTTCFN AKGPLLKKEL SSFIDKGQEL CADYSENTFT EYKKKLAERL KAKLPDATPT ELAKLVNKRS DFASNCCSIN SPPLYCDSEI DAELKNILVD HHHHHH 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.
