Case study: customized variant characterization

 

A case study for our product characterization service demonstrates a flexible strategy for variant characterization. The choice of a lean, agile strategy using online technologies coupled with MS to direct identification empowers you to achieve more time-efficient methods suitable for pre-clinical stages.

 

 

We also offer an extended strategy that uses semi-preparative column fraction collection and in-depth characterization. This approach empowers you to understand variants with low detection limits and obtain comprehensive assay results for a more detailed analysis.
