Fig. 1: The third instar larval cuticle proteins on a 15% acrylamide nondenaturing gel stained with Coomaasie Blue. Lane 1: The cuticle proteins of third instar larvae from the wildtype stock (oreR) crossed into an ome¹ background, Lane 2: wildtype, Lane 3: ome¹/ome¹ homozygote stock. The wildtype bands are numbered in white. The arrows indicate the modified protein bands 5 and 6. Protein 6 is variant in the homozygote mutant (see Chihara and Kimbrell, 1986).
