PR1MA™ qMAX Green qPCR Mix with Blue Tracking Dye

• Superior sensitivity and fast cycling with exceptional results
• Ideal for low copy number templates
• Early Ct values and detection across a broad dynamic range
• Ready to use 2X Master Mix
• Includes PR1MA™ Hot Start Taq Polymerase for greater specificity and accuracy 

Supplied as a ready-to-use 2X master mix, PR1MA™ qMax Green has been engineered for high sensitivity, fast cycling, and excellent reproducibility. PR1MA™ 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.

PR1MA™ Protein Markers

PR1MA™ All Blue, Regular Range Protein Markers

PR1MA™ All Blue, Regular Range Protein Markers are blue protein standards with 10 or 11 pre-stained proteins covering a wide range of molecular weights from 10 to 180 kDa in Tris-Glycine buffer (9 to 170 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 72 kDa, in the presence of Tris- Glycine buffer) are enhanced in intensity.

Loading Volume

• 3 μL or 5 μL per loading for clear visualization during electrophoresis on a 15-well or 10-well mini-gel
• 1.5~2.5 μL per well for general Western blotting transfer

The markers are supplied at a concentration of approximately 0.1~0.5 mg/ml of each protein in the buffer (20 mM Tris-phosphate, pH 7.5 at 25°C, 2% SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15% (v/v) Glycerol)

PR1MA™ Tricolor Protein Markers

PR1MA™ Tricolor Protein Markers are three-color protein standards with 10, 12, or 13 pre-stained proteins covering a wide range of molecular weights from 5 to 245 kDa in Tris-Glycine buffer (3.5 kDa to 235 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands, one green and one red band (at 25 kDa and 75 kDa, respectively, in the presence of Tris-Glycine buffer).

Loading Volume

• 3 μL or 5 μL per loading for clear visualization during electrophoresis on a 15-well or 10-well mini-gel.
• 1.5~2.5 μL per well for general Western blotting transfer.

The markers are supplied at a concentration of approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol).

PR1MA™ Taq

• Ideal for routine PCR applications as well as genotyping, colony PCR, and fast PCR
• Improved template affinity and solubility for higher enzyme activity and greater yields
• Proprietary buffer optimized for a variety of assay conditions
• Conveniently supplied as a 2X Master Mix or in a 2-tube format of polymerase and separate 5X buffer

PR1MA™ Taq provides superior results for routine applications. Modified to improve DNA-binding, this polymerase offers higher solubility and greater template affinity, resulting in consistently superior performance. PR1MA™ Taq Polymerase exhibits a 5' to 3' nuclease activity, but no 3' to 5' (proofreading) activity and works well with a wide range of DNA templates including GC-rich sequences.

The polymerase is supplied with a 5X buffer containing MgCl2 and a proprietary mix of enhancers (dNTP's not included). For convenience, PR1MA Taq is also available in a ready-to-use 2X Master Mix - just add primers and template DNA. Our "Red Dye" Master Mix incorporates a red-loading dye that allows amplified samples to be loaded directly on an agarose gel.  The red color aids in visualization during pipetting, and higher density of the buffer ensures that the samples will drop into the gel wells.
