Immunoassays are bioanalytical methods that generally use antibodies to detect and quantify specific analytes, often proteins, in biological samples. The process involves the capture of a target protein by an immobilized antibody, followed by its detection with another antibody conjugated either to enzymes, such as phosphatase alkaline or horseradish peroxidase…

Immunogenicity refers to the ability of a substance, such as an antigen or a vaccine, to provoke an immune response in an organism. The recognition of the substance as foreign triggers an immune response, which involves the production of antibodies and the activation of immune cells to fight against or…

KCAS is a rapidly growing industry leader that continues to increase its vast knowledge surrounding assay transfers not only internally but externally as well.  As KCAS expands as a global leader in the bioanalytical space we have taken our knowledge surrounding internal assay transfers and extended that knowledge to external…

Ligand binding assays (LBAs) have been our core activity for decades. LBAs are commonly used to measure interactions between two proteins, a ligand and its receptor, a monoclonal antibody (mAb) and its target, or biologics and Anti-Drug Antibodies (ADA). Throughout the development of New…

With recent guidance released from the FDA, there are changes for PKs (Pharmacokinetics) and ADCs (Antibody Drug Conjugates) that must be clearly understood before making decisions for your drug product testing. ADCs combine the target specificity of monoclonal antibodies with the…

Biologics are drugs derived from complex molecules like antibodies. Over the last two decades they have re-emerged as…

Clinical research carries significant risks and numerous obstacles that must be overcome to achieve success. Identifying the ideal Contract…

Being that it is a relatively “niche” segment of the industry, there are several key areas that need to be considered in the field of molecular services related to cell and gene therapies. First and foremost, it is important to recognize that regulatory guidelines within this field are…

Anyone who has been following KCAS for any amount of time has likely heard us discuss the advantages of Hybrid LC-MS/MS for the bioanalysis of large molecules. As pioneers in the technology for many years, KCAS has become a strong proponent of working with our customers to demonstrate the quality…

Due to the relative maturity of the technology, most people’s instinct when thinking about bioanalysis of large molecules is towards ligand binding assays. However, we urge people to be open to a more flexible approach. Using hybrid LC-MS/MS can be an equally useful tool for quantitation of biological therapeutics and…
