2932448-10	1985	The phosphate ester must be located to C-2 of xylose/xylitol as the 1-3H radioactivity could be released by periodate oxidation when it was preceded by alkaline phosphatase treatment.	Tritium	70-72	complement C2	Bos taurus	39-42	
3790504-6	1986	From previously measured isotope effects, we predict the loss of tritium from the 1(R)-2H and 1(S)-2H samples to be 74:8 for a syn relationship between cleavage at C-1 and C-2 vs. 21:90 for an anti relationship.	Tritium	65-72	complement C2	Bos taurus	164-175	
435461-4	1979	The configurational purity of tritium at C-2 of dopamine and C-1 of the dopamine precursor 3-methoxy-4-hydroxyphenethylamine has been confirmed employing dopamine-beta-hydroxylase (specific for the pro-R hydrogen at C-2) and pea seedling amine oxidase (specific for the pro-S hydrogen at C-1).

435461-4	1979	The configurational purity of tritium at C-2 of dopamine and C-1 of the dopamine precursor 3-methoxy-4-hydroxyphenethylamine has been confirmed employing dopamine-beta-hydroxylase (specific for the pro-R hydrogen at C-2) and pea seedling amine oxidase (specific for the pro-S hydrogen at C-1).	Tritium	30-37	complement C2	Bos taurus	216-219	
8090-1	1976	At pH 8.9 and 37 degrees C the half-times for tritium exchange with the C-2 protons of the histidines of trypsin are 73 days for His-57, and greater than 1000 days for His-40 and His-91.	Tritium	46-53	complement C2	Bos taurus	72-75	
4454-3	1976	This was accomplished by a direct comparison of the rate of tritium incorporation into position C-2 of histidine 12 of S-peptide (residues 1 to 20) derived from ribonuclease S, with the rates of deuterium exchange of the four histidine C-2 proton resonances of ribonuclease S under the same experimental conditions.
