Description: Recombinant Human IRBP Protein is produced by E.coli expression system and the target gene encoding Thr321-Leu630 is expressed fused with a 6His tag at the N-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. Gene Symbol: RBP3 Alternative Names: Retinol-binding protein 3; Interphotoreceptor retinoid-binding protein; IRBP; Interstitial retinol-binding proteinEntrez Gene (Human): 5949SwissProt (Human): P10745Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MNHKVHHHHH HMTLRSALPG VVHCLQEVLK DYYTLVDRVP TLLQHLASMD FSTVVSEEDL VTKLNAGLQA ASEDPRLLVR AIGPTETPSW PAPDAAAEDS PGVAPELPED EAIRQALVDS VFQVSVLPGN VGYLRFDSFA DASVLGVLAP YVLRQVWEPL QDTEHLIMDL RHNPGGPSSA VPLLLSYFQG PEAGPVHLFT TYDRRTNITQ EHFSHMELPG PRYSTQRGVY LLTSHRTATA AEEFAFLMQS LGWATLVGEI TAGNLLHTRT VPLLDTPEGS LALTVPVLTF IDNHGEAWLG GGVVPDAIVL AEEALDKAQE VL 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 ddH2O. 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.
