Anti-CNTNAP3B antibodies are used in the immunodetection of the protein contactin associated protein family member 3B. In humans, the canonical protein has a reported length of 1288 amino acid residues and a mass of 140.4 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. A member of the Neurexin protein family, CNTNAP3B is known to be involved with cell adhesion. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include cell recognition molecule Caspr3b, contactin associated protein like 3B, and contactin-associated protein-like 3B. Indicated applications for CNTNAP3B antibodies listed below include ELISA, Immunofluorescence, and Immunohistochemistry.
