Hi I truly thank so many people that provided suggestions and information regarding my inquire about 'GBS/RADSeq services companies' (which is at the bottom of this message), it was of enormous help!!! I have compiled the information in some order, and included only those companies that I have checked already or that their web page indicate they perform such services. Some companies were mentioned that I do not include here because I know they do not provide GBS services anymore (Cornell), do only sequencing but not library construction (Macrogen) or do other kind of jobs, like Ultra conserved elements (UCEs) (e.g., Rapid Genomics). Highly recommended and mentioned by several: a) The Elshire Group: https://www.elshiregroup.co.nz/ (based in New Zealand). Rob Elshire invented GBS sensu stricto (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0019379). He and Robyn Johnston are fantastic to work with, their offer high-quality services, and their prices are globally competitive. b) Diversity Arrays Technology: http://www.diversityarrays.com (based on Australia but with partners in other parts). Service provider for the joint generation of thousands of polymorphic SNPs and dominant markers for non- model organisms. Their technique is called DArTSeq. We had very good experience with them and they can provide results from SNP tables till raw FASTQs if requested, including a BLAST/annotation of all markers against various genomes. c) SNPSaurus: http://snpsaurus.com costs similar to Floragenex, on the high ranges d) Novogene (www.novogene.com), Chinese company, indicated as cheaper than Floragenex e) LGC (http://www.lgcgroup.com/services/dna-sequencing/genotyping-by-sequencing-(gbs)/#.WYVtSYHTXqA); indicated as slow in answering inquires and long project times Others: f) GenoScreen (in France) https://www.genoscreen.fr/en/ g) TexasAMU Genomics http://www.txgen.tamu.edu; http://genomics.tamucc.edu h) Genomix4life (in Italy) http://www.genomix4life.com/en/ i) IGATech (in Italy) http://igatechnology.com j) Center for Anchored Phylogenomics at FSU run by Emily Moriarty Lemmon and Alan Lemmon (http://anchoredphylogeny.com). Partnership between researchers and the Center (from organization of the project to publication of the study). k) Genohub: https://genohub.com/ They don't do the work themselves but rather contact a number of companies which then place bids to do the work you want them to do. If you accept the low bid, then the company contacts you and you make arrangements to send of your DNA. I've used them 3x now and it's always been cheap, I've got good quality data, and the turn around was fast. Ella Vázquez Domínguez Instituto de Ecología, UNAM Ap.

We need to obtain polymorphic SNPs, data that will be used for population and landscape genomics, annotation for loci under selection, and the sort. The GBS or single/double RadSeq service we need includes library preparation; we will provide the appropriate DNA samples of different animal species (initially rodents). We wish to obtain the raw data (fastq files) from which to perform the Bioinformatics (no need the service companies to do it). I have already contacted these companies: Data2Bio and Floragenex (they already gave me some quotes); Genewiz and HudsonAlpha (still waiting to hear from them); and GenScript and Edinburgh Genomics (do not provide such services). evazquez@ecologia.unam.mx
