Multiplication‐stimulating activity for chicken embryo fibroblasts from rat liver cell conditioned medium: A family of small polypeptides

Dulak, Norman C., Temin, Howard M.·1973·Journal of Cellular Physiology

Abstract

A partially purified multiplication‐stimulating activity for chicken embryo fibroblasts in cell culture was isolated from rat liver cell conditioned medium (see preceding paper, Dulak and Temin, 1973). It has been analyzed by isoelectric focusing and by polyacrylamide gel electrophoresis in sodium dodecyl sulfate. Multiplication‐stimulating activity resided in a family of at least four polypeptides which were similar in apparent molecular size, but different in electrical charge. These polypeptides have a specific activity of about 50,000 with respect to serum. One of them has been purified on a small scale to apparent homogeneity in a sodium dodecyl sulfate polyacrylamide gel.

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.
