Recombinant Rat Retinol-binding protein 4 (Rbp4)

• 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.

• Molecular Weight:

• 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℃.
