🚨New preprint alert!! Introducing "GlycoFASP" - a super easy method to isolate pure O-glycopeptides from complex samples. Pioneered by Shane and @keira_erol, they show that you can simply add sample + glycoprotease to a MWCO filter -> O-glycopeptides 10.26434/chemrxiv-2025-bxv0k

Such an honor to be the first grad of the Malaker lab!
HUGE congratulations to my very first PhD student, @VRAdoesMS, who graduated yesterday and is now officially a doctor!! 🎉🎉🎉 They gave an amazing defense talk and we had an epic celebration. Super proud and exited for them!! 🍾🥂

Congrats to @VRAdoesMS and @joann_chong!! 🥳🥂The paper is officially online now @J_ASMS: https://t.co/zMBTa6Zuv2 Also, check out this really awesome cover art 😍
Hey there, O-glyco enthusiasts! Do you use PNGaseF before your glycoproteomics runs? If so, you might want to check for "free" N-glycans hanging around in your sample. Check out @VRAdoesMS and @joann_chong's new preprint: 10.26434/chemrxiv-2024-568nn

🥳A bit of good news today before the chaos begins (or continues?) -- Our paper was published today @JProteomeRes! Big congrats to @joann_chong along with co-authors @VRAdoesMS, @keira_erol, and @TarynMLucas! Check it out here:

Protein glycosylation is a complex post-translational modification that is generally classified as N- or O-linked. Site-specific analysis of glycopeptides is accomplished with a variety of fragment...
Have you ever wondered how often N- 🟦and O- 🟨glycans modify the same peptide? We did too! Check out our new preprint online now, spearheaded by @joann_chong with help from @VRAdoesMS, @keira_Erol, and @TarynMLucas! 🧵👇
