Intra-crystalline protein degradation dating of proboscidean enamel from the UK (NERC Grant NE/K500987/1)

The concentration of both L and D amino acid isomers was determined by HPLC (High-performance liquid chromatography) for multiple amino acids. 30 samples of proboscidean enamel were taken from the collections at BGS. Samples of enamel (~30 mg) was removed from the teeth of proboscideans using a small electric drill. All of the samples were from UK sites dating to the Quaternary. These samples were used to build a regional geochronology based on the extent of racemisation of amino acids from the intra-crystalline fraction (Dickinson, 2018).

A published paper 'A new method for enamel amino acid racemization dating: A closed system approach' is also available; https://doi.org/10.1016/j.quageo.2018.11.00 5

Statement

Samples of enamel (~30 mg) were powdered and exposed to NaOCl (12%) for 72 h. The NaOCl was removed and the powdered enamel was washed 5X with water and 1X with MeOH. Powdered enamel samples were split into 2 fractions. One sample was treated for their free amino acid (FAA) content and the other their total hydrolysable amino acid (THAA) content. THAA samples were dissolved in HCl (7M) and heated at 110 ̊C for 24 h. THAA samples were re-dissolved in HCl (1 M, 20 μLmg−1) and FAA samples were demineralised in HCl (1 M, 25 μLmg−1). KOH (1 M, 28 μLmg−1) was added to the acidified solutions. The sample was centrifuged for 10 min causing a clear supernatant to form above a gel; the biphasic separation. The supernatant was extracted and dried by centrifugal evaporation and analysed by HPLC. All methods are outlined in Dickinson et al., 2019.
