A-Z of ancient DNA protocols for shotgun Illumina Next Generation Sequencing v1

This collection contains established ancient DNA (aDNA) specific protocols for Illumina next generation sequencing. It covers sampling of skeletal remains for regions preserving higher amounts of aDNA, DNA extraction methods designed for retrieval of very short DNA fragments, and various library construction methods (including treatments for the 'removal' of typical aDNA damage). All protocols have been adapted after published protocols (see each for the corresponding original publication), and are used primarily in the Department of Archaeogenetics at the MPI-SHH (Jena, Germany). All protocols in this collection can be used together, and in some cases swapped out with others. All protocols prior indexing are mostly performed in a dedicated ancient DNA laboratory - please see the guidelines section of each protocol for more information. The order of protocols is as follows: 1. Sampling for aDNA Sampling of Pars petrosa (os temporale, ''petrous bones') for human aDNA extraction Sampling of teeth for human and microbial (e.g. pathogen) aDNA extraction Sampling of dental calculus for oral microbiome aDNA extraction 2. Retrieval of DNA Ancient DNA Extraction from Skeletal Material (based on the Dabney et al. 2013 Proc Natl Acad Sci U S A protocol) Ancient DNA extraction from dental calculus (based on the Dabney et al. 2013 Proc Natl Acad Sci U S A with extra washing steps from Ozga et al. 2016 Am J Phys Anthropol) 3. Library Preparation Library Adapter Preparation for Dual-Index Double Stranded DNA Illumina Sequencing (based on Meyer and Kircher 2010 Cold Spring Harb. Protoc. protocol) Non-UDG Treated double-stranded ancient DNA library preparation for Illumina sequencing (requires 3.1, based on Meyer and Kircher 2010 Cold Spring Harb. Protoc. protocol) Half-UDG Treated double-stranded ancient DNA library preparation for Illumina sequencing (Variant of 3.2, with partial damage removal treatment from Rohland et al. 2015 Philos Trans R Soc Lond B Biol Sci) Full-UDG Treated double-stranded ancient DNA library preparation for Illumina sequencing (Variant of 3.2, with complete damage removal treatment from Briggs et al. 2010 Nucleic Acids Res) Dual-Indexing of aDNA libraries for Illumina Sequencing (based on Meyer and Kircher 2010 Cold Spring Harb. Protoc. protocol) 4. Preparation for Sequencing Amplification and Pooling for dual-indexed Illumina library for sequencing
