SDS-PAGE (Sodium dodecyl sulfate polyacrylamide gel electrophoresis), according to the method of
Laemmli, was performed to analyze the proteins present in samples, with a 12 percentage separating gel and
4.5% stacking gel. The criterion lysozyme was used to recognize the lysozyme bands. 20µl samples were
burdened in every well and the electrophoresis departure was performed at 100 Voltage for about 45 min. The
protein bands were discoloured with Coomassie Brilliant Blue R-250 (0.1g CBB in 40 ml methanol and 10 ml
acetic acid and 50 ml distilled water) for 1hr and destained by dispersal in destaining solution (10 ml methanol
and 5ml acetic acid and 85 ml of distilled water)10
