In preparing for metamorphosis insects store in their hemolymph and fat bodies a major nutrient reserve of 500-kDa hexamerins. At least three hexamerins serve this function in Lepidoptera, including arylphorin (ArH) and two high methionine proteins (M-MtH and V-MtH). Six day-old adults of Manduca sexta Abbreviation: / ArH: arylphorin M-MtH: moderately high methionine hexamerin PBS: phosphate buffered saline V-MtH: very high methionine hexamerin Vg: vitellogeni
