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
