Stretton Scientific have launched a re-usable, custom oligo array platform for any species, any genome. The advantages include: no minimum order size - due to the fact that the arrays are synthesised on a silicon chip rather than printed; and the arrays can be stripped and reused for a total of 4 hybridisations per slide making them extremely economic and flexible. The arrays are available in 3 size formats 4 x 2k (16hybs), 12k and 90k.
