SEQUENCE ANALYSIS OF SOMATOMEDIN-C: CONFIRMATION OF IDENTITY WITH INSULIN-LIKE GROWTH FACTOR I
Abstract
Somatomedin-C (Sm-C) was purified from Cohn fraction IV of human plasma by previously published methods. Purity was established by SDS polyacrylamide electrophoresis followed by silver staining of the gel. Amino acid analysis of an acid hydrolysate revealed no significant discrepancies from the amino acid composition of insulin-like growth factor I (IGF-I). The first 24 residues beginning at the amino terminal glycine were identical to the corresponding residues in IGF-I. Tryptic and chymotryptic degradation followed by determination of the amino acid composition and sequence of the resultant peptides was used to complete the primary structure of Sm-C. The results of these studies document that Sm-C and IGF-I are identical peptides, thus supporting previous observations that Sm-C and IGF-I are qualitatively and quantitatively indistinguishable in radioligand and biological assay systems.

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.
