Fig. 1. Protein Profiles of the silkworm PM in the 5th day of the fifth instar. (A): 1D SDS-PAGE pattern of PM proteins extracted from the B. mori. Each gel lane was cut into 7 bands (PM1 to PM7) followed by in-gel digestion used for shotgun analysis. The letters ‘M’ and ‘S’ represent protein marker and sample, respectively. (B): Distribution of isoelectric points (pI) and molecular weight (MW) for all of the proteins identified by the shotgun approach.
