Zooarchaeology by Mass Spectrometry
NCC is now accepting submission forms for ZooMS sample processing
Zooarchaeology by Mass Spectrometry (ZooMS), more formally known as collagen peptide mass-fingerprinting by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, is a rapidly expanding analytical method designed to identify the taxa of morphologically unidentifiable animal remains; namely bone. The technique extracts peptides stored within Type I Collagen of bone, ivory, eggshell and other animal remains, runs them through a MALDI-TOF mass spectrometer, and compares the resulting peptide peaks to a pre-established database. When the peptide peak results match a set of peaks listed in the database, the species of the otherwise unknown sample is identified. These species-specific peptide peaks are called the Peptide Mass Fingerprint (PMF) for that species.
This paleoproteomics technique has been serving the fields of archaeology, cultural heritage, ecology, and forensics for just over a decade (Buckley et al. 2009). Compared to aDNA analysis, ZooMS is minimally destructive and more cost-effective. It also produces more reliable results due to the higher survival rate of collagen than DNA in severe conditions and over long periods of time. This survivability is partially due to Type I Collagen’s abundance within animal matter, making up 95% of collagen and 80% of all proteins. These factors have driven the field of ZooMS to expand rapidly, with related publications over doubling in the past five years alone (Brown et al. 2021a).
While this technique is useful across various fields, it was initially developed by and for archaeologists. As a result, this is where the majority of its development has centered. Examples of its uses in archaeology span from discovering symbolic expression through species selection for Iroquoian bone points (McGrath et al. 2019), to identifying hominin remains from nearly 10,000 bone fragments at Denisova cave (Brown et al. 2016, 2021b, 2021c), and species identification of leather shoe parts from medieval Denmark (Ebsen et al. 2019). Other uses include identifying remains in museum collections and identifying animal-based components in works of art (Fiddyment et al. 2015; Kirby et al. 2013). Identification of ivory (Coutu et al. 2016) and wild African bovids (Janzen et al. 2021) also opens up the potential to use ZooMS in tracking illegal trade of ivory products and bushmeat.
Facilities and Instrumentation
NCC’s ZooMS sample processing lab is run out of the 4Front Technology & Office Campus at
3510 Hopkins Pl N, Oakdale, MN 55128
NCC has an established relationship with the Center for Metabolics and Proteomics (CMSP) in the College of Biological Sciences at the University of Minnesota. Samples prepared at the ZooMS lab are brought to the CMSP labs on the U of M St. Paul campus and run through the center’s MALDI-TOF for final spectra results.
