These small nuclear ribonucleoprotein 70kDa (U1) ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. small nuclear ribonucleoprotein 70kDa (U1) is an alias of the human SNRNP70 gene, which encodes the protein, small nuclear ribonucleoprotein U1 subunit 70. Notably, small nuclear ribonucleoprotein 70kDa (U1) is known to play a role in RNA splicing, among other functions. The SNRNP70 protein is 437 amino acid residues in length and 51.6 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the nucleus of the cell. This protein is known to be phosphorylated. Other names for this target antigen include RNPU1Z, RPU1, and SNRP70.
