Results of non-reducing sodium dodecyl sulphate polyacrylamide gel electrophoresis of the supernatant and aggregate precipitate formed in refolding process show that except being refolded to native egg white lysozymes, the reduced-denatured lysozymes can also form the aggregates with molecular weights being separately about 30.0 and 35.0 kD, while the reducing SDS-PAGE and the refolding results in the presence of sodium dodecyl sulphate show that these aggregates are formed chiefly through the misconnection of disulfide bonds between the reduced-denatured lysozymes, and the aggregate precipitates are formed through the non-covalent interactions between the aggregates with molecular weight being about 30.0 kD.

复性过程形成的上清和集聚体沉淀的非还原电泳结果表明，除了能复性成天然态的溶菌酶分子外，还原变性蛋白溶菌酶同时还能形成分子量分别约为30.0KD和35.0KD的蛋白溶菌酶分子集聚体；而它们的还原电泳和在SDS存在时的复性结果表明，这些集聚体主要是通过还原变性蛋白溶菌酶分子间的二硫键错配而形成，而集聚体沉淀则是通过分子量约为30.0KD的集聚体分子之间的非共价相互作用而形成。
