The vast difference between the theoretical protein concentration and experimental protein concentration of the unknowns showed that bradford protein assay must have limitations the coomassie dye only interacts with certain amino acids such as: arginine, histidine, lysine, tyrosine, tryptophan and phenylalanine. Antibody titer determination and recombinant protein quantitation in developing custom protein assays that are easier to process than elisas, while still . Protein-protein interaction research this luminescence assay is the alternative to colorimetric, fluorometric and radioisotopic assays for the quantitative . In conclusion, spectrophotometric dnph assay coupled to protein fractionation by hplc provides more quantitative information than the simple spectrophotometric assay, but it has the disadvantage that protein mixture fractionation by hplc cannot completely separate proteins of close molecular weights. The system comprises a dedicated reader, state-of-the-art analysis software and a growing portfolio of lunaris™ multiplex protein assay kits for the detection and quantification of protein biomarkers, such as soluble inflammation and immune-response factors.
