The profiles of red fluorescent proteins with antinucleopolyhedrovirus activity in races of the silkworm Bombyx mori

Partially purified red fluorescent proteins (RFPs) secured from the gut juice of 5th-instar multivoltine and bivoltine silkworm races were observed as several bands in electrophoretograms and chromatographic eluates. Interestingly, different races of silkworms had varying numbers of fluorescent protein bands: 11 in Pure Mysore (resistant), 11 in Nistari (resistant), 4 in CSR2 (moderately susceptible) and 1 in NB4D2 (highly susceptible).
