Table 1. Comparison of automatic data acquisition mode analysis of single base extension products of an A/T mutation with different 3-HPA matrices.

Matrix	Valley between heterozygote A/T peaks (%)a	Failed sample spots (%)b
Standard 3-HPA	85.3 ± 5.1	23.9
Fucose-doped 3-HPA	67.3 ± 6.7	11.5

96 MALDI samples were spotted on SpectroCHIPs and analyzed in automatic data acquisition mode.

^a100% corresponds to no resolution between the two peaks (see Figs 6 and 7).

^bPercentage of spots not resolved where the two peaks were detected as only one broad peak.
