Description
The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX) is designed for reverse transcription and quantitative real-time analysis of a specific target RNA by one-step reaction. The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX), consisting of One-Step RT Enzyme Mix and 2X One-Step Master Mix, is a convenient kit designed for highly efficient cDNA synthesis and highly specific real-time PCR in a single tube. The One-Step RT Enzyme Mix contains a thermostable ExcelRT™ Reverse Transcriptase and a RNAok™ RNase inhibitor. Consequently, One-Step RT Enzyme Mix can reverse transcribe RNA to cDNA at a wide temperature range from 42 to 60°C and active against RNase A, RNase B and RNase C. By containing specialized hot-start Taq DNA polymerase, which greatly reduce primer-dimer formation and can be activated within 2 minutes, the 2X One-Step Master Mix features high specificity and is suitable for fast cycle program.

PACE® GENOTYPING ASSAY
ABOUT
PACE (PCR Allelic Competitive Extension) genotyping chemistry is a homogeneous, PCR-based allele-specific technology for the analysis of DNA sequence variants, most commonly SNPs (Single Nucleotide Polymorphisms) and Indels (insertion / deletions).
PACE genotyping chemistry is comprised of two parts:
- PACE Genotyping Assay: two allele-specific forward primers and one common, reverse primer. The allele-specific forward primers each have different 3′ terminal bases reflecting the target variant, and a unique 5’ tail sequence which is incorporated as part of the fluorescent signal mechanism.
- PACE Genotyping Master Mix: containing all remaining components required for PCR and the generation of fluorescent signals. PACE Genotyping Master Mix contains a novel, universal, fluorescent reporting cassette to produce machine-readable fluorescent signals (FAM and HEX) corresponding to the assay genotypes.
When combined with sample DNA, these components create a PACE Genotyping Reaction, as illustrated in the figure below.
We have extensive knowledge and experience in assay design, especially when it comes to allele-specific PCR. PACE Genotyping Assays are available to purchase either Validated and Unvalidated. Validated assays require customer DNA to validate and optimise, for guaranteed performance. Unvalidated assays are designed in silico and supplied untested.
REQUIRED COMPONENTS
- qPCR machine or Thermocycler + Fluorescent plate reader
- PCR plate or equivalent and appropriate optically clear seal
- Template DNA
- PCR-grade water
- PACE Genotyping Master Mix or PACE 2.0 Genotyping Master Mix
STEPS TO YOUR PACE GENOTYPING ASSAY DESIGN
- Place your order on this page. Our support team will contact you by email.
- Fill out an Assay Design Template form with all the information we need to process your custom PACE Genotyping Assay order. We will email you a copy of the template when we first contact you, or your can download a copy here.
- Email your completed Assay Design Template to [email protected]
- Using the information you provide us, we will create your PACE Genotyping Assay designs, order the oligos, and send you design sequences.
- Once we receive the oligos, we assemble the assay(s) and then ship an aliquot to you (unvalidated) or test on your DNA samples before shipping the aliquot to you (validated).

GENTLE MIXING OF SAMPLES
By planar orbital motion
German designed and manufactured, BioShake XP plate mixer offer an ultra-efficient, 2-dimensional shaking axis so that samples mix completely in a fraction of the time of competing systems.
The mixing orbit of 2.0 mm is always constant. The orbital shaking is precisely controlled, in fact, that you need never spin down your plates after mixing. Even tubes, vials, high density plates, or low sample volumes, offer no obstacle for these precision tools.
Fully adjustable between 200 rpm and 3,000 rpm, well beyond the speeds of most other brands, guarantees fast, splatter-free, mixing for tubes, glass vials or across an entire 384-well microplate.
COMFORT
Simple intuitive operation and programming
The BioShake XP is operated from the front face of the enclosure which includes touch buttons and a display.
Special buttons for start, stop and storage of time and mixing modes enable the instrument to run complex applications. This opens new points of view on the daily laboratory work and optimizes routine application enormously.
The short mix button allows short and fast mixing in between.
The two line LCD display guarantees simultaneous and safe reading of all programmed and measured parameters as time and mixing frequency.
UNIVERSAL SPRING CLAMPS
Suitable for all microplates
In the corners eight spring clamps are inserted for easy fixation of skirted microplates and deep well plates in SBS format 127.7 x 85.5 mm without an attached adapter. These spring clamps lock the microplate quickly and safely, even at the highest mixing frequencies.
For flexible and deformable PCR plates we recommend using of the related PCR adapter.
Fast mixing processes with frequent plate changes can be performed in the routine as easy and safe.
