Data

Performance data

Uniform on-target coverage independent of operator

Callisto delivers high uniformity and on-target rates. This maximizes use of sequencing reads for better coverage of target regions, reducing the need for excessive sequencing depth and lowering overall costs.

Charts of Fold-80 uniformity, on-target rate and coverage for Callisto versus manual IDT xGen hybridization, including operator comparison.

Plexing with up to 20 libraries without loss in uniformity

Pooling more libraries into a single hybridization capture reaction on Callisto allows for greater throughput without compromising on uniformity and on-target percentages. Up to 480 libraries can be processed simultaneously using an exome panel.

Excellent target coverage for difficult to capture regions (RB1 and TERT)

RB1 and TERT are difficult to capture cancer associated genes due to their high GC content and repetitive sequences. Hybridization capture on Callisto yields higher than 90% on-target percentages with high depth of coverage in these two gene regions of interest, with minimal or no dropouts for both high GC and low GC regions.

Accurate detection of low frequency variants with Callisto over manual preps

The EGFR rs121434568 C>T SNP occurs at a low expected frequency of 1% in the Horizon cfDNA reference sample. Hybridization capture on Callisto accurately identified the C>T variant at the expected frequency of 1%.
