Mean relative abundance (%) ±SEM of proteins from French Alpine, Creole, and Nubian goat breeds, as well as from Holstein Friesian cows’ skimmed milk samples, resolved in 4–20% gradient polyacrylamide gel under denaturing and reducing conditions. Gels were stained with colloidal Coomassie blue G-250 and documented using the GelDoc EZ imager (Bio-Rad). Data were recorded and integrated as optical density from gel band peak areas using Image Lab 5.0 software (Bio-Rad). LF: lactoferrin, SA: seroalbumin, HC Ig: Heavy chain Immunoglobulin, AC: alpha-casein, BC: beta-casein, KC: kappa-casein, b-LG: beta-lactoglobulin, a-LA: alpha-lactoalbumin. A, B, and C indicate a significant statistical difference among breeds and species (p < 0.05).
