Polynucleotide probes

Fig. 1. Light-directed synthesis of polynucleotide probe arrays. Exposure to light through a photolithographic mask is used to remove protecting groups from surface sites in pre-defined regions of a functionalized glass substrate. A solution of an activated polynucleotide building block is then applied, which reacts specifically in the exposed regions of the substrate. Repeated cycles of illumination-deprotection and monomer coupling are used to construct a two-dimensional array of probe sequences...

A wide variety of hybridization conditions can be expected for this heterogeneous group of solid phases. The hybridization time depends on the nature of the solid phase and complexity of the strand in excess and may range from that comparable to membrane hybridization (Section 8.2 e.g., microtiter plates and polynucleotide probes), to a few minutes (small particulate solid phase will display a hybridization rate which approaches that of solution hybridization Table 3.16).
