Phospho-INSR (Tyr1158) Recombinant Rabbit Monoclonal Antibody (8H20L22), Invitrogen™

Descripción

This antibody is predicted to react with non-human primate, mouse and rat based on sequence homology. Intact IgG appears on a non-reducing gel as ∽150 kDa band and upon reduction generating a ∽25 kDa light chain band and a ∽50 kDa heavy chain. Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.

INSR is a receptor tyrosine kinase. Binding of insulin to the extracellular domain of INSR stimulates glucose uptake. INSR and IGF-1 receptors share major structural and functional similarity. The earliest cellular response to insulin stimulation is autophosphorylation of tyrosine in INSR. In humans, the INSR gene is located on chromosome 19. Defects in INSR are the cause of various insulin resistance syndromes and IGF-1R defects may also cause some forms of growth retardation.
