Unique cytogenetic dGH™ and Pinpoint FISH™ platform for disease research, mutation detection and diagnosis
Verification of the Human Genome Database Contig Orientation using custom dGH Assay
dGH* Chromatid Assays
*Directional Genomic Hybridization
Detect Translocations and Inversions* in a single simple assay
*Plus other rearrangements and many types of mutations
Inversions and…
…Translocations, Dicentrics…
(plus another inversion)

Use dGH Probes for Pinpoint FISH Assays
High resolution FISH assays using single stranded probes • Probes designed using KromaTiD’s proprietary
bioinformatics tools • No Repetitive Sequences; COT Free
High Resolution By Design with 6KB Targets
Pinpoint FISH
Metaphase
7q22CUX1 FISH Probe GREEN 5q31KIF20A FISH PROBE RED
Interphase
Better performance in existing platform and equipment • Applicable in both interphase and metaphase
cells
7q22CUX1 FISH Probe GREEN 5q31KIF20A FISH PROBE RED
Multi-‐Colored FISH Assay with 10 kb Resolution
Pinpoint FISH Performance
Better Performance • 3X the relative signal; 3X the resolution
• 6X the signal-‐to-‐noise ratio; 50% lower background
Easier to Use • Free of repetitive sequences by design -‐-‐ no blocking
required
• Consistent hybridization quality
Flexible Design & Reliable Synthesis • Synthetic probes vs. cloned DNA
• Detect smaller mutations and mutations with variable breakpoints
Single Stranded Defined Probes
