PEGylated Oligonucleotide Analysis

Novatia offers LC/MS analysis of PEGylated oligonucleotides on our LTQ-Orbitrap mass spectrometer using our ProMass Deconvolution technology. This analysis can reveal:

1. The molecular weight distribution of a PEGylated oligo;

2. How much free oligo is present in a sample; and

3. What the lot-to-lot consistency (or variability) is among multiple samples.
