Analytical Assays
Multiplex analysis
Multiplex immunoassays allow simultaneous detection and quantification of multiple analytes in a single sample from a variety of biological specimens including but not limited to serum, plasma, CSF, cell culture supernatants, sputum.
xMAP Technology has application in serological assays by easy detection of antibodies. A serology assay enables the detection of an antibody (target) with the use of a capture protein antigen attached to the surface of a microsphere. A detection antibody that incorporates a fluorescent label is used to quantify the amount of target antibody present. This assay is useful when serum antibodies need to be measured, such as for the response to a vaccine, allergic reactions, or autoantibody detection.
It combines the efficiency and sensitivity of traditional ELISAs with high through-put capacity, small sample volume,efficiency in terms of time and cost,high reproducibility and sensitivityand analyte quantification over a wide range of concentrations.

Biomarker Validation and Qualification
Validation is the process of evaluating the reliability, reproducibility and accuracy of the biomarker across a range of experimental conditions. Qualification process provides an evidentiary link between the biomarker and biological processes/clinical end points.
Following validation and qualification, a biomarker can be used to diagnose the risk, presence and prognosis of a disease in an individual. In evaluating potential drug therapies, a biomarker may be used as a surrogate for a natural endpoint such as survival or irreversible morbidity. If a treatment alters the biomarker, which has a direct connection to improved health, the biomarker serves as a surrogate endpoint for evaluating clinical benefit. Some of the main areas in which molecular biomarkers are used in the drug development process are: early drug development studies, safety studies, proof of concept studies, and molecular profiling.
