Anti-ApoB-48 antibodies enable researchers to detect and measure the ApoB-48 antigen in biological samples. This target is a reported synonym of the APOB gene, which encodes apolipoprotein B. This protein is known to function in TNF-mediated cellular signaling pathways and cholesterol metabolism and homeostasis, among other biological roles. The human version of ApoB-48 has a canonical amino acid length of 4563 residues and a protein mass of 515.6 kilodaltons. It is reported to be localized in the cytoplasm and is secreted of cells. Other names for this target antigen include FCHL2, FLDB, and LDLCQ4. Western Blot is a widely used application for the ApoB-48 antibodies listed below. In addition, ELISA is also a common application.
