Product Specific Information
This antibody is predicted to react with equine, mouse, rabbit and rat based on sequence homology.
ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
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.
Background/Target Information
Tight junction group of proteins are a cell-to-cell adhesion structure in epithelial cells that constitute the epithelial junctional complex with adherens junctions and desmosomes. Tight junction strands are mainly composed of claudins, occludin, and JAM. Occludin is a 65 kDa protein and is considered to be vital in the assembly and maintenance of tight junctions. At the tight junction, occludin associates with membrane peripheral protein ZO-1. The expression of occludin varies greatly on the type of tissue. It is continuously and highly expressed in brain whereas non-neural tissues show lower expression and discontinuous distribution. Overall structural features of the occludin protein are highly conserved in all the species examined. Under-expression of tight junction proteins, including occludin, is a key molecular abnormality responsible for the increased permeability of tumor endothelial tight junctions, which contributes to brain tumor edemas
