Looking for a new approach to quantification of #deamidation in your MALDI-TOF data? Then you need to check out our new preprint!!! Fei Yang will be speaking about it at ISBA11_Torino tomorrow in Methods 5 at 16:00! #palaeoproteomics www.biorxiv.org/content/10.1...

MALDI Deamidation Score (MDS): A Fast and Flexible Method for Assessing Deamidation in ZooMS Data and Its Application to the Denisova Cave Bone Assemblage

Estimating deamidation from MALDI-TOF MS spectra of bones has most frequently been achieved using the q2e method due to its high-throughput capacity and ease of use. Despite this accessibility, q2e is...

Week 11 – Pottery and Residues
This week is all about how ancient people did not wash their pottery very well and how grateful we should all be about that. Take a look at these studies from Çatalhöyük, Turkey (dx.doi.org/10.1038/s414...) and Baħrija, Malta (dx.doi.org/10.1007/s007...)

Week 10 – Ancient Textiles
The precious nature of textiles makes them such a unique view point into the archaeological world. Here are two papers on how ancient proteins can help us understand Pre-Columbian textiles (dx.doi.org/10.1016/j.ja...) and Viking clothing (dx.doi.org/10.1016/j.jp...)

Week 9 – Dental Calculus
If you don’t finish this week’s readings with a powerful urge to brush your teeth, then I am not doing my job. Welcome to the wonderful world of dental calculus, from the Neolithic link.springer.com/article/10.1... to the Bronze Age www.nature.com/articles/s41...

Week 8 – Enamel
Enamel might be the hardest tissue in the body but it will hold a tender place in your heart… too much? Check out enamel proteins for sex estimation (dx.doi.org/10.1002/ajpa...) And this (very advanced - sorry 😅) paper on a Rhino tooth from Dmanisi (dx.doi.org/10.1038/s415...)

Week 7 – Eggshell
Welcome to the fascinating world of eggs! #Darwin would have loved this one. Look how far back in time we can recover eggshell proteins in this paper (dx.doi.org/10.7554/eLif...) and PMF approaches to their study in this paper (dx.doi.org/10.1080/2054...)

Protein sequences bound to mineral surfaces persist into deep time

A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

Week 6 – Archaeological bone
You need to read this absolute STUDENT FAVOURITE paper on Iroquoian bone points (dx.doi.org/10.1038/s415...) and (OK this is not really an intro paper) but this multi-protease study highlights so many possibilities in studying bones (dx.doi.org/10.1016/j.jp...).

Since it’s Darwin Day take a look at the evolutionary history of his fav ungulates (dx.doi.org/10.1038/natu...) and this paper on birds (dx.doi.org/10.1093/zool...) to dip your toes into shotgun proteomics on ancient specimens

Week 2 – ZooMS!
It feels impossible to choose only two papers but I think you have to read the OG ZooMS paper (dx.doi.org/10.1002/rcm....). And this study on domestication in southern Africa is a really nice example of what ZooMS can do! (dx.doi.org/10.1038/s415...)

Species identification by analysis of bone collagen using matrix‐assisted laser desorption/ionisation time‐of‐flight mass spectrometry

To celebrate #DarwinDay I thought I’d share some of the papers from my Intro to #Palaeoproteomics course (in my previous life as a lecturer). If you’re interested in the study of ancient proteins these are some fun papers to start with! (Don’t worry, this is not just a list of my own research😊🤣)

I feel like I need a computer science degree to figure out how to print in colour 🖨️😵‍💫
First I turned off "print in grayscale".
Then I went into properties and turned on colour printing.
THEN I went into advanced and did the same... It's still printing in B&W
