HOW LONG SHOULD CUSTOMARRAY PROBES BE FOR HYB & SEQ?
We have successfully used probes with melting temperatures of 50 to 70ÂșC. Depending upon G-C content, the probes can range from 14 to 35-mer (optimal: 17 to 28-mer). If shorter probes are used, the addition of a 5 to 10-mer oligo(dT) linker will prevent the effects of proximity to the chip surface.
