These PCTK3 ELISA kits are immunodetection tools for measuring the levels of PCTK3 in biological samples. PCTK3 is an alias of the human CDK18 gene, which encodes the protein, cyclin dependent kinase 18. Notably, PCTK3 is known to play a role in protein phosphorylation, among other functions. The CDK18 protein is 474 amino acid residues in length and 54.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. Other names for this target antigen include PCTAIRE and PCTAIRE3. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
