These CEP90 ELISA kits are immunodetection tools for measuring the levels of CEP90 in biological samples. CEP90 is an alias of the human PIBF1 gene, which encodes the protein, progesterone immunomodulatory binding factor 1. Notably, CEP90 is known to play a role in cilium assembly, among other functions. The PIBF1 protein is 757 amino acid residues in length and 89.8 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. Its subcellular localization is in the cytoplasm and is secreted. In terms of tissue specificity, it is reported be expressed at highest levels in testis. Other names for this target antigen include C13orf24 and JBTS33. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
