Abstract

The purification from bovine pituitary gland of a growth factor responsible for the control of animal cell division in tissue culture is reported. This growth factor is a polypeptide of 13,300 molecular weight and is homogeneous when analyzed by polyacrylamide gel electrophoresis, carboxymethyl-Sephadex gradient elution chromatography, and Sephadex G-50 chromatography. The yield of growth factor is 5 mg per kg of pituitary. It is active in stimulating DNA synthesis in 3T3 cells at concentrations as low as 2 times 10-13 M with saturation at 1 times 10-10 M.

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.
