In this episode, Drs. Steven Lowes and Barry Jones discuss hybrid assays, combining immuno-affinity with liquid chromatography-mass spectrometry (LC-MS). This is a growing area of opportunity for protein bioanalysis.

Topics covered include:

  • What is meant by hybrid assay
  • Reasons to choose a hybrid assay
  • Top down vs bottom up
  • Specific challenges
  • Assay design considerations
  • Future potential for this type of bioanalysis

...I think that fundamental point about more sensitivity, and associated with that is more selectivity, is going to be part of the future adoption of these hybrid assays. We have needs already, we can see needs for looking at quantifying proteins in very small samples, say tissue biopsies. - Steven Lowes
