[A comparative study of total protein and albumin in man, monkey, dog and rat employing different analytical methods (author's transl)].

In the present study, serum albumin was determined colorimetrically in three animal species and in man with the help of four currently used dye-reagents (protein binding reagents). The results were compared with those obtained from corresponding electrophoretic and biuret determinations, using Versatol as a standard-control throughout. Using 2-(4-hydroxyazobenzene)-benzoic acid and bromocresol purple as reagent for the albumin determinations, species-specific differences from the electrophoretic results were found. No such differences occurred with bromo-cresol green, except in rats. There was no significant difference in albumin concentrations between man, monkeys and rats. Total protein concentration was only similar in man and monkeys.
