ABSTRACT
A new method for quantitation of ovalbumin by thin layer isoelectric focusing in polyacrylamide gel is described. This technique separates ovalbumin from avian-magnum homogenates or egg white and allows the quantitative determination of each ovalbumin fraction. Considering the very small amount (7 mul) of sample needed for an analysis, the sensitivity and the reproducibility of the proposed method are good. The application of this technique to quail egg white ovalbumin analysis leads to the characterization of four fractions A3, A2, A1 and A0 containing, respectively, 0, 1, 2 and 3 atoms of phosphorus per mole and with isoelectric points that range from 4.95 (A3) to 4.65 (A0).
