| pubmed-article:3817155 | pubmed:abstractText | Immunoperoxidase electrophoresis was applied to the plasma of a patient showing a high level of prolactin (PRL) secreted by a pituitary adenoma. Two PRL monomers were detected with an anti-hPRL antiserum: a major 22 kDa form and a minor 25 kDa form. Concanavalin A-Sepharose 4B chromatography revealed that the 25 kDa form was a glycosylated variant of PRL. Incubation of this variant with endoglycosidase F led to its transformation into the 22 kDa form. | lld:pubmed |
