Identification and purification of glial growth factor.
Cultured rat Schwann cells are stimulated to divide by a protein growth factor, present in extracts of bovine brain and pituitary, which we have named glial growth factor (GGF). Two lines of evidence indicate that GGF activity in both brain and pituitary resides in a protein of Mr = 31,000. (1) Four independently isolated monoclonal antibodies that immunoprecipitate the activity react with an a...
متن کاملPurification of Multiple Forms
A method to fractionate com (Zea mays L. B73) mitochondria into soluble proteins, high molecular weight soluble proteins, and membrane proteins was developed. These fractions were analyzed by both sodium dodecyl sulfate-polyacrylamide gel electrophoresis and assays of mitochondrial enzyme activities. The Krebs cycle enzymes were enriched in the soluble fraction. Malate dehydrogenase has been pu...

15 صفحه اولIdentification, purification, and characterization of truncated forms of the human nerve growth factor receptor.
We report the presence of truncated forms of the nerve growth factor receptor (NGFRt) in the conditioned medium of the human melanoma cell line A875 and in human urine and amniotic fluid. Radioiodinated nerve growth factor (125I-NGF) specifically bound to NGFRt was chemically cross-linked. After immunoprecipitation, labeled receptor species were visualized by autoradiography following sodium do...
متن کاملGranulocyte/macrophage colony-stimulating factor from mouse lung conditioned medium. Purification of multiple forms and radioiodination.
Four forms of mouse granulocyte/macrophage colony-stimulating factor (GM-CSF) were purified 100,000-fold from mouse lung conditioned medium. Each of the CSF species stimulated the formation of both granulocyte and macrophage colonies, and half-maximal stimulation in the semi-solid mouse bone-marrow colony assay occurred at 1 pm. The four GM-CSF species exhibited similar charge microheterogeneit...
