Anti-GRAB antibodies enable researchers to detect and measure the GRAB antigen in biological samples. This target is a reported synonym of the RAB3IL1 gene, which encodes RAB3A interacting protein like 1. This protein is known to function in exocytosis and protein transport, among other biological roles. The human version of GRAB has a canonical amino acid length of 382 residues and a protein mass of 42.6 kilodaltons, although 2 isoforms have been identified. Other names for this target antigen include guanine nucleotide exchange factor for Rab-3A and RAB3A interacting protein (rabin3)-like 1. Indicated applications for GRAB antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
