  • Ready to use 2x mastermix.
  • Includes Accuris Hot Start Taq Polymerase for greater specificity and accuracy.
Supplied as a ready-to-use 2X master mix, qMax Green has been engineered for high sensitivity, fact cycling and excellent reproducibility. Accuris Hot Start Polymerase provides accurate PCR of a variety of templates including low copy number and difficult sequences, while the proprietary qMax Green intercalating dye exhibits higher fluorescence and lower PCR inhibition than other popular green dyes.

These two components are supported by a specially formulated buffer with an exacting combination of salts, PCR enhancers, stabilizers and pH that results in earlier Ct values and a high specificity across a broad dynamic range.

Bulk Packaging:
To accommodate the requirements of high throughput users, Accuris is now  offering their full line of qPCR and RT-qPCR reagents in bulk packaging at highly discounted prices. Bottle sizes of 25 mL (2500 reactions) and 50 mL (5000 reactions) are available for qMAX SYBR Green and qMAX Probe mixes. One Step RT-qPCR kits are also available in bulk format for 2500 and 5000 reactions and are ideal for labs performing pathogen detection.

PetriSeal™ Sealing Film

 

PetriSeal™ stretches and conforms to form a tight seal and is temperature resistant, waterproof and chemically resistant. It resists abrasion and puncture and blocks vapor loss while reducing the rate of gas exchange. Use PetriSeal™ with microtiter plates, Petri dishes and culture plates to prevent to entry of contaminants. The seal remains flexible down to -30°C and can withstand continuous exposure from -40°C to +77°C (with intermittent exposure up to 100°C). Tests have shown that PetriSeal™ leaves no adhesive residue even after two years.

 

Colors: Blue, Clear, Red, White & Yellow

Tape Size: 0.50 In. x 108 Ft.
