Anti-PROTO-LB antibodies enable researchers to detect and measure the PROTO-LB antigen in biological samples. This target is a reported synonym of the AKAP13 gene, which encodes A-kinase anchoring protein 13. This protein is known to function in bone development and cardiac muscle cell differentiation, among other biological roles. The human version of PROTO-LB has a canonical amino acid length of 2813 residues and a protein mass of 307.6 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the membrane, nucleus, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include AKAP-Lbc, AKAP-Lbc, and ARHGEF13. Indicated applications for PROTO-LB antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
