In #JPM2023 news, $SEER also presented. They are another of the Next Generation Proteomics Sequencing players. One of their USPs is that they have an approach capable of finding different protein variants that would be undistinguishable with affinity-based approaches. 
This includes slice variants, where the "Peptide Level" identification allows them to detect meaningful differences where other approaches are not able to.
Since their method is based on peptides, they can go into the 1M+ elements per run, where panel-based affinity methods are limited to the thousands or maybe tens of thousands.
Looking ahead to 2023, SEER intends to accelerate population-scale studies, expand the installed base, enhance the Data Analysis suite, and capture new markets.
