Description: Recombinant Human VSIG4 Protein is produced by Mammalian expression system and the target gene encoding Arg20-Pro283 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: VSIG4 Alternative Names: CRIg; Z39IG; V-set and immunoglobulin domain-containing protein 4; Protein Z39IgEntrez Gene (Human): 11326SwissProt (Human): Q9Y279Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : RPILEVPESV TGPWKGDVNL PCTYDPLQGY TQVLVKWLVQ RGSDPVTIFL RDSSGDHIQQ AKYQGRLHVS HKVPGDVSLQ LSTLEMDDRS HYTCEVTWQT PDGNQVVRDK ITELRVQKLS VSKPTVTTGS GYGFTVPQGM RISLQCQARG SPPISYIWYK QQTNNQEPIK VATLSTLLFK PAVIADSGSY FCTAKGQVGS EQHSDIVKFV VKDSSKLLKT KTEAPTTMTY PLKATSTVKQ SWDWTTDMDG YLGETSAGPG KSLPVDHHHH 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.
