The ExcelDye™ 6× DNA Loading Dye (Orange) is pre-mixed buffer for tracking the DNA sample during the electrophoresis on agarose or polyacrylamide gels. It contains one dye (Orange G) for tracking the DNA migration. The Orange G migrates at approximately 30 bp on a standard 2% TAE agarose gel (50 bp on 1% TAE agarose gel). The included glycerol keeps the DNA at the bottom of the well and the presence of EDTA chelates divalent metal ions to prevent the process of metal-dependent nuclease.

The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and template. The master mix features high sensitivity and signal intensity as well as low background and better compatibility with cDNA templates derived directly from reverse transcription reaction mixture. The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) contains hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. This master mix allows for sensitive, precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules. With inert smart blue contrast dye, the ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process. The ExcelTaq™ 2X Q-PCR Master Mix is also compatible with a ROX reference dye if recommended by the manufacturer of the qPCR system.
Features
High sensitivity and signal intensity
Smart blue contrast dye as a visual aid for reaction setup
Better compatibility for reverse transcription
Low background
Storage
Protected from light. Aliquot to avoid multiple freeze-thaw cycles. -20°C for 12 months

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.

Peptone :15.0g
Yeast extract powder: 3.0g
Sodium chloride: 5.0g
Sodium lauryl sulfate:0.1g
Agar: 12.0g
Chromogenic substrate 6.5g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 41.6g of the product, adding 1.0L distilled or deionized water, heated to boiling stirring until completely dissolved, dispensing into flask, 115 autoclaved for 10minutes.
2. Take 25.0g or 25.0ml of sample with sterile procedures , added to the flask containing 225.0mL of sterile phosphate buffered saline (or saline) , shaken thoroughly homogenized with a homogenizer or a 1:10 dilution of 1min solution, diluted 1:10 and then continue to select the appropriate serial dilutions of three, the two plates inoculated with each dilution, poured dissolved by heating and cooled to about 45 medium.
3, observe the results.
