ActoFactor™ Recombinant Human Retinol binding protein 4, plasma
- Specification
Cat.No.
CSC-CTK0512
Description
Retinol binding protein 4 (RBP-4) belongs to the lipocalin family and is the specific carrier for retinol (vitamin A alcohol) in the blood. This protein was found to be expressed and secreted by adipose tissue, and was strongly associated with insulin resistance. It delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin which prevents its loss by filtration through the kidney glomeruli. RBP-4 delivers retinol from the liver to the peripheral tissues. In plasma, the rbp-retinol complex interacts with transthyretin, this prevents its loss by filtration through the kidney glomeruli. Human recombinant RBP-4 produced in E. coli is a single, non-glycosylated, polypeptide chain containing 184 amino acids and having a molecular mass of 21 kDa.
