Important notice!

Primer schemes have now been migrated to labs.primalscheme. Rather then contributing to this repo, we now encourage that you contribute primer schemes designed with varVAMP to primerschemes. Use primal-page to create correctly formatted input data.

ViralPrimerSchemes

This repo contains wet-lab evaluated and non-evaluated primer schemes for full-viral genome sequencing of highly diverse viral pathogens designed with varVAMP.

Tiled schemes

Primers can contain ambiguous characters in order to achieve pan-specificity. We recommend using a One-Step-RTPCR Protocol at 60°C primer annealing for 35 to 40 cycles. Due to the variability of some viruses, we can not garantuee that the primers will work for every sample you are trying to sequence but for the large majority they should perform resonably well. Happy sequencing!

Virus Genotypes Amplicon Size GenomeRecovery Evaluated Primers Input alignment Full varVAMP output
HEV 3 (f, e) 1000-1500 99.0 % tsv aln output
HEV 3 (c, h1, m, i, uc, l) 1000-1500 99.3 % tsv aln output
ratHEV all 1200-1700 97.4 % tsv aln output
Polio 1-3 1000-1400 99.6 % tsv aln output
HAV all 1000-1600 95.6 % tsv aln output
BoDV all 400-550 98.6 % tsv aln output
SARS-CoV-2 B.1-XBB 260-365 99.7 % 🔲 tsv aln output

Which files should I check?

If you just want to use the primers, just go for the tsv files in the primer section. If you are interested in the full varVAMP output (here you can also find additional non-used primers) have a look at the input alignment to get a feeling for the variability and have a look here for an explanation on the output files. If you want to design primers yourself, the outputs can also help you in understanding how the software works and how to prepare the data and set the parameters for a successful scheme design.
