Abstract

Abstract A simplified procedure for purification of terminal deoxynucleotidyl transferase is presented. The enzyme is shown to be homogeneous by equilibrium centrifugation and gel electrophoresis. The molecular weight of the enzyme is 32,360, with a v measured as 0.65 cc g-1. The homogeneous enzyme can be dissociated into two subunits, α and β, by sodium dodecyl sulfate. Subunit molecular weights, estimated from gel electrophoresis, are α = 8,000 and β = 26,500.

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.
