Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human IGFBP5, different from the related mouse and rat sequences by two amino acids.
- Molecular weight context: reported MW: 23 kDa; calculated MW: 30570 MW
- Reactivity: Human
- Applications: ELISA, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Insulin-like growth factor-binding protein 5; Insulin-like growth factor-binding protein 5. Insulin-like growth factor-binding protein 5?is a?protein?that in humans is encoded by the?IGFBP5?gene. The expression of?IGFBP5?by stable transfection and adenovirus-mediated infection is inhibitory to growth in 2 human breast cancer cell lines.?IGFBP5?expression leads to G2/M cell cycle arrest and apoptosis. Stable expression of?IGFBP5?in the breast cancer cell lines also inhibits the formation and growth of tumors following injection in athymic mice. It is concluded that IGFBP5?is a growth inhibitor and proapoptotic agent in breast cancer cells. Additionally, IGFBP-5 is expressed by fibroblasts, myoblasts and osteoblasts, making it the predominant IGFBP found in bone extracts. It has a strong affinity for hydroxyapatite, allowing it to bind to bone cells. When bound to extracellular matrix, IGFBP-5 is protected from proteolysis and potentiates IGF activity, but when it is soluble, IGFBP-5 is cleaved to a biologically inactive 21?kDa fragment (1,?2). Functional note: IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Reported localization: Secreted. Expression/tissue context: Osteosarcoma, and at lower levels in liver, kidney and brain.
