Anti-Solo antibodies enable researchers to detect and measure the Solo antigen in biological samples. This target is a reported synonym of the ARHGEF40 gene, which encodes Rho guanine nucleotide exchange factor 40. This protein is known to function in axon guidance and GPCR signaling pathways, among other biological roles. The human version of Solo has a canonical amino acid length of 1519 residues and a protein mass of 164.7 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Indicated applications for Solo antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
