2X XtraWhite Master Mix GL and 2X XtraRTL Master Mix GL (Genespin proprietary formulation), are two premixed, ready-to-use solution containing Xtra-Taq Pol, dNTPs and MgCl2 in a Reaction Buffer optimized for use in PCR amplification of targets present in low copy number and to avoid amplification of non-specific products. Both buffers contain 3.0mM magnesium, PCR enhancers and thickening agents (vortex thoroughly prior to use). 2X Master Mix Standard GL contain an internal fluorescent stain for DNA detection on Agarose gel directly after PCR amplification.
2X XtraRTL Master Mix GL contains Orange G dye that allows gel loading and electrophoresis of the sample directly from the PCR tube, without further manipulation. 2X XtraWhite Master Mix GL is supplied with appropriate quantity of 6X Loading Dye. The Orange G dye migrates at the same rate as a duplex DNA fragment of approximately 50 Kbp and does not interfere with DNA migration when it is used as a loading dye for agarose gel electrophoresis.
