The concentration of tryptophan was estimated fluorometrically in whole plasma from
several species after ultrafiltration to remove tryptophan bound to plasma proteins. The
major portion of the tryptophan was protein-bound in all of the species, although the degree
of binding decreased in the order: dog, rabbit, rat, cat, rhesus monkey, sheep, man, horse,
green monkey, marmoset, cow, pig, guineapig, mouse, turkey, chicken. Thus tryptophan
binding to plasma proteins seems to be a characteristic of many warm-blooded animals.
