The Fluorometric Estimation Of Lactoflavin

Research Lamoratories of the Dry Milk Company, Inc., Bainbridge, New York

ABSTRACT

Pure, crystalline lactoflavin has been prepared from a water-soluble vitamin concentrate derived from milk. A method of estimating lactoflavin involving its fluorescent properties in "black light" is presented. The method is simple, involving only standard lactoflavin solutions and an ultra-violet light generator equipped with a suitable filter. The method was found to be accurate to 0.1 of lactoflavin, but concentrations as low as 0.05 /ml. of lactoflavin could be detected.

The assistance of Dr. B. L. Herrington, temporarily employed by The Dry Milk Research Laboratories, is also gratefully acknowledged.
