How many SNPs and samples are assayable with a GoldenGate OPA?
The lowest number of SNPs assays available within one GoldenGate OPA or panel is 96 SNPs (on the BeadXpress platform). Above that, GoldenGate OPAs are available from 384 (on the BeadXpress platform) up to 1,536 SNPs (on the BeadArray platforms) in multiples of 96. Multiple OPAs can be run per sample. One tube of OPA can query 96 samples (one Sentrix Array Matrix).
