63. A method for determining hybridisation of an array of probes with a target nucleic acid, which method comprises
(a) contacting target nucleic acid with each hybridisation probe of the array under conditions to hybridise the probe to the target nucleic acid, and optionally removing unhybridised material, wherein each probe comprises a mass label linked to a known base sequence of predetermined length wherein each mass label comprises a photoexcitation group; - and
(b) identifying the hybridised probe by mass spectometry. - View Dependent Claims (64, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81)
