Recombinant Rat Retinol-binding protein 4 (Rbp4)

Recombinant Rat Retinol-binding protein 4 (Rbp4)

• CAS Number: 9000-83-3
• Gene Name: Rbp4
• UniProt: P04916
• Expression Region: 19-201aa
• Organism: Rattus norvegicus
• Target Sequence: ERDCRVSSFRVKENFDKARFSGLWYAIAKKDPEGLFLQDNIIAEFSVDEKGHMSATAKGRVRLLSNWEVCADMVGTFTDTEDPAKFKMKYWGVASFLQRGNDDHWIIDTDYDTFALQYSCRLQNLDGTCADSYSFVFSRDPNGLTPETRRLVRQRQEELCLERQYRWIEHNGYCQSRPSRNSL
• Tag: N-terminal 6xHis-tagged
• Source: E.coli
• Field of Research: Signal Transduction
• Assay Type: Developed Protein
• Relevance: Retinol-binding protein that mediates retinol transport in blood plasma. Delivers retinol from the liver stores to the peripheral tissues. Transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane.
• Purity: Greater than 90% as determined by SDS-PAGE.
• Activity: Not Test
• Length: Full Length of Mature Protein
• 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Storage Conditions: 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℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
