Cuticular proteins in Bombyx genus members and the model for nanocoating formation. a SDS-PAGE of samples from cornea and retina of B. mori [Jp] and B. mandarina. Major protein bands unique for cornea (marked by red arrowheads) were MS-identified (see Additional file 3: Table S1). b The percentage of major cuticular proteins in corneal material from B. mori [Jp], B. mori [Vn] and B. mandarina. c–e Model of step-wise acquisition of nanostructures on the corneal surface of B. mori from Japan (c), B. mori from Vietnam (d), and B. mandarina (e)
