How do I determine the number and cost of target capture probes I will need to target N genes/gene regions on my NGS custom panel?

The number of probes you will need to order and their total cost will vary with the set of genes being targeted. To obtain an accurate assessment, use the free, online Custom Capture Design Tool on our website.

The tool will determine the probes required to obtain optimal coverage depth and uniformity of your gene set, as well as provide a rudimentary design of the probes. The tool can handle up to 1000 genes or genomic regions, or up to 1 Mb of FASTA file sequencing information.

If you need to order probes for a larger set of sequences, please contact
