Anti-HTRA antibodies enable researchers to detect and measure the HTRA antigen in biological samples. This target is a reported synonym of the HTRA1 gene, which encodes HtrA serine peptidase 1. This protein is known to function in chorionic trophoblast cell differentiation and placenta development, among other biological roles. The human version of HTRA has a canonical amino acid length of 480 residues and a protein mass of 51.3 kilodaltons. It is reported to be localized in the cell membrane, cytoplasm, and is secreted of cells and notably expressed in many tissues, such as the nasopharynx and ovary. Other names for this target antigen include ARMD7, ARMD7, and CADASIL2. Indicated applications for HTRA antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
