The newly developed MASTER MAX™ 1-2-3™ Polymerase Chain Reaction (PCR) Beads are premixed and predispensed complete reagents for performing PCR amplifications. The beads contain recombinant HotStart DNA polymerase, made by a manufacturer with extensive experience in reagent ambient stability and purity. These PCR beads have been optimized for endpoint- and intercalating dye-and probe based real-time PCR amplifications. With the exception of 1) primer, 2) template, and 3) water ,the convenient, ambient temperature-stable beads provide all the necessary reagents to perform 25-μl polymerase chain reactions. The beads are available predispensed into either 0.2-ml thin-walled micro-well 8-strip tubes, or 96-well plates (sufficient for 96 reactions). The following components are included in the MASTER MAX™ 1-2-3™ PCR Beads: Room temperature-stable beads containing stabilizers, BSA, dATP, dCTP, dGTP, dTTP, ~2.5 units of a hot-start DNA polymerase and reaction buffer. When a bead is reconstituted to a 25 μl final volume. Each lot of Master Max PCR beads are thoroughly tested for quality and performance. Specifications for release are based on performance, purity and reproducibility of each individually dispensed reaction.
