Purification of human platelet-derived growth factor.
Open accessAbstract
Human platelets contain a polypeptide growth factor that stimulates the proliferation of connective tissue cells. Purification of this platelet-derived growth factor (PDGF) was accomplished by heat (100 degrees C) treatment of washed platelets and subsequent ion-exchange chromatography, gel filtration in 1 M acetic acid, isoelectric focusing, and preparative sodium dodecyl sulfate/polyacrylamide gel electrophoresis. PDGF has an isoelectric point of 9.8 and a molecular weight ranging from 13,000 to 16,000 as judged by gel filtration in 1 M acetic acid or analytical sodium dodecyl sulfate gel electrophoresis under reducing conditions. The specific activity of the purified PDGF is 20 million times greater than that found in unfractionated human serum. Purified PDGF stimulates replicative DNA synthesis and cell proliferation in quiescent density-arrested cultures of BALB/c 3T3 cells at concentrations of 1 ng/ml (0.1 nM).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
