Anti-Growth Hormone 2 antibodies are used for the immunodetection of the protein encoded by the GH2 gene. In humans, the canonical protein has a reported length of 217 amino acid residues and a mass of 25 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 4 different isoforms for this protein. It is reported to be expressed in the placenta. A member of the Somatotropin/prolactin protein family, it is known to play an important role in growth control. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include GHB2, GHL, GHV, hGH-V, growth hormone variant, growth hormone B2, placenta-specific growth hormone, and GH-V. A number of Growth Hormone 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
