Retinaldehyde-binding protein 1 (RLBP1), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-317aa. Protein Length: Full Length of Mature Protein. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: SEGVGTFRMV PEEEQELRAQ LEQLTTKDHG PVFGPCSQLP RHTLQKAKDE LNEREETREE AVRELQEMVQ AQAASGEELA VAVAERVQEK DSGFFLRFIR ARKFNVGRAY ELLRGYVNFR LQYPELFDSL SPEAVRCTIE AGYPGVLSSR DKYGRVVMLF NIENWQSQEI TFDEILQAYC FILEKLLENE ETQINGFCII ENFKGFTMQQ AASLRTSDLR KMVDMLQDSF PARFKAIHFI HQPWYFTTTY NVVKPFLKSK LLERVFVHGD DLSGFYQEID ENILPSDFGG TLPKYDGKAV AEQLFGPQAQ AENTAF. Purity: Greater than 95% as determined by SDS-PAGE. Endotoxin: n/a. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Soluble retinoid carrier essential the proper function of both rod and cone photoreceptors. Participates in the regeneration of active 11-cis-retinol and 11-cis-retinaldehyde, from the inactive 11-trans products of the rhodopsin photocycle and in the de novo synthesis of these retinoids from 11-trans metabolic precursors. The cycling of retinoids between photoreceptor and adjacent pigment epithelium cells is known as the 'visual cycle'. Reference: n/a. Function: nan
