What is an endpoint assay?

An endpoint assay is a type of experiment used to measure a specific biological or chemical activity at a single, defined point in time. Unlike continuous or kinetic assays, which track changes over time, an endpoint assay provides a snapshot of a reaction or process once it has reached a specific point or equilibrium. These assays are commonly used in various fields, including drug development, to assess the effect of a compound by measuring a final readout, such as cell viability, enzyme activity, cell population dynamics and status,or protein and gene expression.

How do I choose the best endpoint analysis for my study?

The best endpoint analysis for your study will depend on the goal of the study and the mechanism of action of your agent. For example, you will want to measure your agent ability to kill tumor cells with a cell viability assay ex vivo or by tumor growth inhibition in vivo; additionally, you may want to use flow cytometry and imaging to measure immune cell population shifts/movement if you are testing an IO agent, or use comet assay to measure DNA damage if testing an agent that targets the DNA damage/repair mechanism, or use NGS or proteomics and Luminex/ELISA to measure changes in DNA or protein expression if you agent is expected to modify DNA/protein expression level. Our experts can help you identify the best endpoint analysis and help you plan your study efficiently and successfully.

What endpoint assays does Champions offer for clinical studies?

At Champions we can perform several assays for clinical studies: our NGS, PCR, IHC, Luminex/ELISA, and Flow Cytometry are all GCLP compliant.

What sample types are needed for endpoint assays?

The sample type needed will depend on the endpoint assay and can vary from supernatant, to dissociated cells, to tissue chunks.
