Proteomic characterization of royal jelly proteins in Chinese (Apis cerana cerana) and European (Apis mellifera) honeybees

摘要

In this study, the proteins contained in royal jelly (RJ) derived from Chinese and European honeybees have been analyzed in detail and compared. Remarkable differences were found in the heterogeneity of major royal jelly proteins (MRJPs), MRJP2 and MRJP3, in terms of molecular weight and isoelectric points between the two species of RJ. MRJP2 and MRJP3 produced by Chinese honeybee are less polymorphic than those produced by European honeybee. This study is a contribution to the description of the royal jelly proteome.
