The HTRA ELISA kits listed below utilize specific antibodies for the plate-based assay of HTRA in various samples. HTRA is another term for the HTRA1 gene, which encodes the protein, HtrA serine peptidase 1 in humans. It has been reported that HTRA plays a role in chorionic trophoblast cell differentiation and placenta development, among other functions. Structurally, the HTRA1 protein is described to be 480 amino acid residues in length and 51.3 kilodaltons in mass. Its subcellular localization is in the cell membrane, cytoplasm, and is secreted. In terms of tissue specificity, it is found to be widely expressed, with strongest expression in placenta. Other names for this target antigen include ARMD7, ARMD7, and CADASIL2.
