METHOD FOR CALORIMETRIC DETERMINATION OF THE LIPOPROTEIN LIPASE ACTIVITY IN HUMAN PLASMA ENVIRONMENT

摘要

A method for calorimetric determination of the lipoprotein lipase activity in human plasma comprising steps of preparing a reagent, obtaining and preparing human plasma sample, filling the isothermal titration calorimetry cell withe prepared human plasma sample, injecting LPL to the cell from the syringe-stirrer, changing the heat rate as a result of injection of LPL into ITC cell with human plasma, increasing LPL concentration in the ITC cell by at least one injection, performing isothermal titration calorimetry measurements, recording total hydrolysis of plasma lipids by LPL, recording differences in how well LPL can get access to the lipids, determing the influence of added regulators on the LPL reaction in plasma.
