SPATA21 ELISA kits are immunoassay tools for the measurement of the protein spermatogenesis associated 21, which is encoded by the SPATA21 gene in humans. Functionally, this protein is reported to be involved in differentiation of haploid spermatids. The canonical protein structure is reported to have an amino acid sequence of 469 residues and a mass of 52.2 kDa. As many as 2 protein isoforms have been reported. Other alias names for this target include spermatogenesis-associated protein 21. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
