Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
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.
Gene References into Functions
  1. RBP4 levels increased by 2-fold in the serum of nonobese Goto-Kakizaki rats but not high-fat diet fed rats. PMID: 26923513
  2. plasma RBP4 concentrations were associated with cardiovascular disease. In addition, RBP4 increases the proliferation of vascular smooth muscle cells induced by hyperinsulinism via activation of MAPK signaling pathway PMID: 24888764
  3. Retinol binding protein 4 promotes hyperinsulinisminduced proliferation of rat aortic smooth muscle cells. PMID: 24604418
  4. Decreased trophoblast expression of retinol transport proteins suggest that nitrofen may interfere with the fetal retinol transport resulting in reduced pulmonary RBP and TTR levels and causing pulmonary hypoplasia in CDH. PMID: 22015466
  5. Steatotic liver grafts are more predisposed to down-regulate retinol-binding protein 4 and overexpress proliferator-activated receptor-gamma. PMID: 21487070
  6. RBP4 contributes to the pathogenesis of insulin resistance in spontaneously hypertensive rats. PMID: 21365528
  7. Increases in RBP4 or Nampt/visfatin do not accompany obesity and insulin resistance in the models examined. PMID: 18401839
