Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of various lysates using RBP4 Recombinant antibody (82934-1-RR)

    WB analysis using 82934-1-RR (same clone as 82934-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 82934-1-RR (RBP4 antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 82934-1-PBS in a different storage buffer formulation.

  • Affinity and Kinetic Characterization of 82934-1-RR

    Affinity and Kinetic Characterization of 82934-1-RR

    Biolayer interferometry (BLl) kinetic assays of 82934-1-RR against Human RBP4 were performed. The affinity constant is below 1 pM.

Background Information

RBP4 (retinol-binding protein 4) is a carrier protein that transports vitamin A (retinol) from the liver to the peripheral tissues. Synthesized primarily by hepatocytes and adipocytes as a 21 kDa non-glycosylated protein, RBP4 is secreted into the circulation as a retinol-RBP4 complex. In plasma the RBP4-retinol complex is bound to transthyretin (TRR), which prevents prevent kidney filtration. Two truncated forms of RBP4, RBP4-L (truncated at Leu-183) and RBP4-LL (truncated at Leu-182 and Leu-183), exist by proteolytic process. RBP4-L and RBP4-LL, which do not bind TTR, are normally excreted into the urine but accumulate in the serum during renal failure. Urinary RBP4 has been reported as marker for glomerular disease. RBP4 also was identified as an adipokine that elevated in some INS-resistant states. Measurement of serum RBP4 could be used to assess the risk of INS resistance, type 2 diabetes, obesity, and cardiovascular disease. (18752671, 16034410)
