Are you struggling to find a suitable commercial ELISA to monitor the consistency of your vaccine?
Maybe you use a novel cell line or have host cell proteins from multiple organisms?
Or do you see HCP-ELISA issues, for instance, related to dilutional linearity?
Learn how Mass Spectrometry (LC-MS) quantifies each protein impurity – with high reproducibility – and down to low ppm levels.
As a bonus, the assay also quantifies individual viral proteins or added residual proteins, such as recombinant enzymes.
