Surfactant Protein A contains a number of potential glycosylation sites and other post translational modifications (SwissProt) which may explain its migration at a higher molecular weight than predicted.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Surfactant Protein A antibody [6F10] (ab51891)
ab51891 staining sections of human lung at 1:3000 dilution. Immunoreactivity is seen with alveolar type II cells, nonciliated bronchial cells and a subset of alveolar macrophages.
