Abstract

A simple method for the determination of tryptophan residues in proteins is described. The method involves (a) treatment of the protein with an excess of 2-hydroxy-5-nitrobenzyl bromide, (b) purification of the labeled protein by gel filtration and ethanol washing, (c) measurement of the absorbance at 410 mµ to determine the number of colored groups incorporated, and (d) a determination of the total protein content by conventional methods. The procedure has been shown to be accurate with a wide variety of proteins.

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.
