Abstract

To characterize the sericin components of the cocoon of silkworm Bombyx mori, fresh cocoon shells were dissolved in saturated aqueous lithium thiocyanate containing 2-mercaptoethanol, and fractionated by ethanol precipitation. Cocoon sericin was found to mainly consist of three polypeptides having molecular masses of the 400, 250, and 150 kDa estimated by SDS-PAGE, which corresponds to the sericin present in the middle, anterior, and posterior part of the middle silk gland. The amino acid compositions of the 400 and 150 kDa components were similar to each other, but that of the 250 kDa component was different. This suggests differences in the coding gene and properties of the 250 kDa sericin from the other two.

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.
