The ELISA kits listed below target C19orf57, the symbol for the human gene, chromosome 19 open reading frame 57. The protein encoded by C19orf57 has a predicted amino acid length of 668 and a mass of 69.6 kDa. There are currently 2 reported isoforms. C19orf57 may also be known by the following names: pre-T/NK cell associated protein (3B3), and uncharacterized protein C19orf57. The human ortholog of the gene is an available target of several ELISA kits.
