Invitrogen™ Claudin 18 Recombinant Rabbit Monoclonal Antibody (34H14L15)

Rabbit Recombinant Monoclonal Antibody

Supplier:  Invitrogen™ 700178

Catalog No. PI700178

Description

This antibody is predicted to react with chimpanzee, equine, rat and Rhesus monkey 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.The immunogenic sequence for this antibody is GFKASTGFGSNTKNH, and the antibody is predicted to react with chimpanzee, equine, rat, and Rhesus monkey based on sequence identity and similarity. 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.

Claudin-18 is a tight junction protein expressed as lung-and stomach-specific isoforms which are generated by alternative splicing of the claudin-18 gene. The lung-specific form is a downstream target gene regulated by the T/EBP/NKX2.1 transcription factor. A splice variant lacking the C-terminal cytoplasmic domain also exists in mouse, but has not been confirmed in human. Human claudin-18 demonstrates 88% amino acid sequence identity to the mouse protein. Immunohistochemical studies have demonstrated complete membrane localization of claudin-18 in lung and stomach epithelial cells, while electron microscopy has shown that it is concentrated in the cell-cell borders of these cells. These features suggest a potentially important role for claudin-18 in the structure and function of tight junctions in the lung and stomach. Claudin-18 expression has also been reported in the inner ear.
