Large Molecule Solutions
LBAs continue to be the primary tool used in the biopharmaceutical sciences to quantitate proteins and anti-drug antibodies in biological fluids and tissues. This assay platform is a useful tool used from early drug discovery, through pre-clinical toxicology work, and clinical studies.
KCAS has an advanced team of Large Molecule specialists.
The approach of analyte capture and digestion or other sophisticated sample preparation techniques combined with LC-MS/MS is used to meet bioanalytical needs for large molecule drug discovery, preclinical, and clinical studies, including bioanalysis of proteins, antibodies, antibody-drug conjugates, biomarkers, and active endogenous compounds in biological fluids and tissues.
