Human SP-D ELISA Kit - 1 Kit (96 Wells)Our Human SP-D ELISA Kit is a sandwich ELISA intended for the quantitative determination of human SP-D in cell culture supernates, serum and plasma (heparin, EDTA).
Surfactant, pulmonary-associated protein D, also known as SFTPD or SP-D, is a protein which in humans is encoded by the SFTPD gene. By fluorescence in situ hybridization, the SP-D gene was localized in 10q22.2-q23.1. On the basis of homology with other collectins, potential functions for SP-D include roles in innate immunity and surfactant metabolism, SP-D is produced in the bronchiolar and terminal epithelium of human fetal lung from about 21 weeks of gestation. Whats more, SP-A and SP-D act as dual-function surveillance molecules that reverse orientation and function and become initiators of host-defense reactions.
