Custom Assays

Upon request, our lab can work with you to develop custom quantitative or qualitative mass spectrometry-based assays to meet the needs of your project. Our primary focus/expertise is in quantitative LC-MS methods for small molecules in blood and urine. However, we have the capability to develop methods for types of analytes in a variety of matrices. Typical lead-time needed for a quantitative, fully validated LC-MS method is 3 to 6 months. However, cost and time requirements are dependent on the compound selected, availability and cost of standard materials, and can vary depending on the complexity of sample preparation needed. We can also perform multiplex immunoassays. Details for a specific project can be obtained by contacting the laboratory directly.
