Biological Mass Spectrometry enthusiast, trying to make sense of cellular hierarchies and heterogeneityhttps://bsky.app/profile/erwinschoof.bsky.socialhttps://bsky.app/profile/erwinschoof.bsky.social/post/3mavv27swm226New preprint! 🚀 We introduce AbTags – antibody–peptide fusion proteins that massively amplify signal, enable absolute quantification of binding events, and are read out together with the single-cell proteome by LC–MS. AbTag platform is patent-pending.

So much great science, amazing people, old & new friends, and not the least, our valuable tech partners. The future of proteomics is clearly still only beginning & we all seem to be enjoying the ride! :)20 Jun 2025 16:14 +0000at://did:plc:cox2nnpy6v6e4vmkeitr7itc/app.bsky.feed.post/3ls2gotrugc2vhttps://bsky.app/profile/erwinschoof.bsky.social/post/3lqsi3q3wbs2bStill figuring out which evening workshop to attend tonight at #ASMS2025? Come on by Ballroom II and hear about hands-on tips and tricks for one of the hottest and fastest developing areas within LC-MS based proteomics, namely single-cell. 😃04 Jun 2025 18:53 +0000at://did:plc:cox2nnpy6v6e4vmkeitr7itc/app.bsky.feed.post/3lqsi3q3wbs2bhttps://bsky.app/profile/erwinschoof.bsky.social/post/3lqjy2ya4ys2sThanks for the kind shout out, Ben! 🙏🏻 Hope to catch you in Baltimore!

Jakob came up with a really clever way to integrate targeted&global proteomics, and together with the @porsebo.bsky.social lab, we pushed the boundaries of what we thought biologically possible. Congrats Jakob!🥳 [contains quote post or other embedded content]01 Jun 2025 09:44 +0000at://did:plc:cox2nnpy6v6e4vmkeitr7itc/app.bsky.feed.post/3lqjxzlgb7k2shttps://bsky.app/profile/erwinschoof.bsky.social/post/3lqhljxkoh22yThe Cell Diversity Lab is well represented at this year's ASMS; please come and talk with Jakob Woessmann and Benjamin Furtwängler to hear all about their latest efforts in improving, and applying single-cell proteomics by MS. #singlecellproteomics #teammassspec #cellheterogeneity31 May 2025 10:55 +0000at://did:plc:cox2nnpy6v6e4vmkeitr7itc/app.bsky.feed.post/3lqhljxkoh22y
