Abstract: A method is developed for determination of the lipoprotein lipase activity. The method is based on the steady state potentiometric titration at constant pH value of higher fatty acids, liberated during the hydrolysis. An oil emulsion intralipid, activated by human blood serum, was used as a substrate. The sensitivity of the method was equal to 0.004-0.010 micronM of fatty acids per min. The reproducibility of the results was 2-5%. This simple and rapid method enabled to study kinetic of reactions, catalyzed by lipoprotein lipases.
