Below are ELISA kits for the investigation of Spa, another term for surfactant protein A1. In humans this protein is encoded by the gene, SFTPA1. The gene is also conserved in other species, including: mouse, rat, frog. This 248-amino acid secreted protein is a member of the SFTPA family. Glycosylation sites have also been identified. Other names for this protein may include: SP-A; SP-A1; COLEC4; surfactant, pulmonary-associated protein A1A. For more detailed ELISA target information, visit the supplier page.
