These p21 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. p21 is an alias of the human NSG1 gene, which encodes the protein, neuronal vesicle trafficking associated 1. The NSG1 protein is 185 amino acid residues in length and 20.9 kilodaltons in mass. However, as many as 2 protein isoforms have been identified.
There are p21 ELISA kits that can detect a target at concentrations as low as 39 pg/mL and as high as 16 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
