AbstractA surface plasmon resonance (SPR) method is described for quantitative determination of α-lactalbumin, β-lactoglobulin, bovine serum albumin, lactoferrin and immunoglobulin G simultaneously in raw and processed milk samples, whey fractions and various milk-derived products, with six samples per assay. Immobilized antibody stability and reproducibility of analyses were studied over time for 25 independent runs (n = 150), giving a maximum relative standard deviation of
