Picky is an oligo design program that alleviates long and monotonous calculations by identifying probes that are very unique and specific to sequence regions. These calculations are based on parameters inputted by the user including optimal probe length, ideal percentage of guanine and cytosine content, salt concentration and the maximum length to which a target sequence matches any non-target sequence.
PICKY allows the rapid and efficient determination of gene-specific oligos based on given gene sets, and can be used for large, complex genomes such as human, mouse, or maize. PICKY can also be used to analyze existing microarray probes and evaluate their design quality. Because PICKY uses rigorous whole genome-based thermodynamic screening to identify potential hydrogen binding sites of each probe, it can also be utilized to design short interference RNA (siRNA) for gene knockout applications and to discover possible targets of regulatory short RNAs (e.g., microRNAs or sRNAs). Picky has exceptional computational capability and is also user friendly.
