Have you seen the article on the analysis of heavily glycosylated IgA antibodies? It uses native ESI and ECD on a ECD upgraded QExactive UHMR? You can access that article here: https://pubs.acs.org/doi/10.1021/jasms.0c00461
It’s well worth a read! And if you are keen doing this as well? We will be happy to send you an offer for an ECD upgrade on your QExactive or Synapt system. Send us a message at email@example.com!
