The TaqMan® GTXpress™ Master Mix delivers accurate genotyping results with robust performance in less than 50 min. Applied Biosystems® TaqMan® GTXpress™ Master Mix (2X) combines AmpliTaq® Fast DNA Polymerase, UP, dNTPs, Tracking Dye, and ROX™ dye in a convenient single vial format. The 50 mL pack (1 x 50 mL) includes reagents sufficient to perform 20,000 PCR reactions (5 µL/reaction).
• Compatible with both Fast and Standard mode thermal cycling conditions
• Pre-mixed components stored at 2°–8°C significantly reduce assay setup time
• Validated with all types of Applied Biosystems® TaqMan® Genotyping Assays
• Extended PCR cycling can be used for poorly amplified or sample-limited reactions The TaqMan® GTXpress™ Master Mix is also sold as part of TaqMan® Sample-to-SNP™ Kit, which provides real-time PCR-ready DNA in 5 min from a wide variety of samples, ranging from blood to buccal swabs to plant tissues. For more information on the TaqMan® Sample-to-SNP™ Kit, refer to the Applied Biosystems® TaqMan® Sample-to-SNP™ Kit Protocol (PN. 4402136).
