Thread 1/5: PREPRINT: A major milestone on
#Paleoproteomics?
Sciex 6600 TripleTOF analyses 99-million-year-old arthropods 🕷️ in amber.
Study identifies proteins from
#Cretaceous #Holothyrida mites &
#Cornupalpatum ticks!

www.researchsquare.com/article/rs-6...Thread 2/5: 🔬 Remarkable coverage of proteins, Elongation factor 1-alpha 71.3%. Impressive coverage of actin.
If confirmed, this would mark the first fossil evidence of Holothyrida mites.
We'll need to examine the PRIDE submission to verify.
Thread 3/5: 🧪 Claims about potential connections to Alpha-gal Syndrome are intriguing but speculative.
Ancient DNA 🧬 and protein studies in amber remain controversial.
Contamination is a persistent challenge that requires careful controls.
Thread 4/5: 🦖 Previous attempts have yielded mixed results.
We found minimal protein preservation in amber-preserved

While they detected amino acids, concentrations were extremely low, highlighting how challenging these analyses are.
