Customer Testimonials

repliQa HiFi toughMix

"I used NEB Q5 for the same plasmid for PCR, same annealing temperature. Only the repliQa HiFi toughMix gave me the correct size products. It is very fast and works much better than NEB Q5 for difficult plasmids in PCR."

Dr. Kara C. UT Southwestern Medical Center

repliQa HiFi ToughMix

"Worked great amplifying two gene target from plasmid DNA. It was the first time I have performed a two step reaction and it worked great. It was awesome running everything in 23 minutes too."

Dr. Brandon L. University of Nebraska

sparQ DNA Frag & Library Prep Kit

"I have built >100 libraries with this kit and the results are great."

Ryan P | Genomics Core Director/Manager West Virginia University

sparQ DNA Frag & Library Prep Kit

“The sparQ kit safeguards samples from over fragmentation and routinely provides more consistent fragment size. Once optimized, I had peace of mind knowing my samples were safe when I got busy in the lab.”

Scientist, Laboratory Manager Agricultural Genomics Institute

qScript XLT cDNA SuperMix

"The cDNA was easy to make and prep was of good quality. I have used 1 ug of total RNA as starting material."

Researcher University of New Mexico

UltraPlex 1-Step ToughMix (4X) Low-ROX

"UltraPlex 1-Step ToughMix (4X) Low-ROX, 500R performs with the same sensitivity when testing using SARS-CoV-2-spiked saliva samples, but is easier to use and at a significantly lower price per reaction. The mix requires little to no time to thaw, decreasing the time required when preparing samples."

Rhoel R. D., PhD, MPH Professor of Infectious Diseases UF Eminent Scholar DIRECTOR, CDC Southeastern Regional Center of Excellence for Vector Borne Diseases

Q qPCR Instrument

"Performing a LAMP assay using a Q-qPCR machine is really comparable with Genie II, however, the higher number of samples that can be analysed at a time and also the appearance of the first amplification signals 2 min earlier than those in Genie II, adds up to its value!"

Steve Baeyen Flanders Research Institute for agriculture, fisheries and food

sparQ PureMag Beads

“Very good product for NGS library purification and size selection”

Senior Scientist MD Anderson

sparQ PureMag Beads

"We found that size selection with sparQ PureMag Beads was similar to our current vendor for but the amount of size selected library recovered was significantly larger."

Kayla Y | Vice President of Operations PHASE GENOMICS

PerfeCTa SYBR Green SuperMix

"PerfeCTa SYBR Green SuperMix has been my first and successful experience that boosted my confidence for qPCR. I am really satisfied with its performance."

Teaching Assistant Ohio University

AccuStart II Genotyping

"With AccuStart II kit we were able to decrease costs, increase yield of our PCR sensitivity while decreasing and optimizing time. It made genotyping much easier, faster, and cheaper for our multiple transgenic colonies."

Laboratory Manager H. Lee Moffitt Cancer Center

sparQ PureMag Beads

"Beads performed as well in my tests as Ampure XP which I consider to be the gold standard.  Impressive results given the lower price for sparQ PureMag Beads."

Charles N | Director of Sequencing Technology University of Southern California

Q qPCR Instrument

“We had the pleasure of testing the ToughMix and the “Q” RT-PCR machine in Mbabane Swaziland in our Tuberculosis Centre of Excellence. The ToughMix stood up to it’s name and had beautiful Ct’s….Considering it’s size, intuititive software and near reproducible Ct curves we’ve decided to add the Q as our workhorse.”

Assistant Professor Infectious Diseases Global and Immigrant Health, Baylor College of Medicine

sparQ DNA Library Prep Kit

"Very easy to use."

Scientist University Sherbrooke

sparQ PureMag Beads

"Great product. Useful for many different types of DNA capture applications."

Phillip B | Associate Professor University of South Carolina

sparQ PureMag Beads

"Worked exactly as advertised. I was able to get complete recovery of my DNA easily and quickly."

Sam G | Postdoctoral Fellow BC CANCER RESEARCH CENTRE

Extracta DNA Prep for PCR - Tissue

"Extracta DNA Prep for PCR  is one of the best, fastest and easiest to use reagent for genomic DNA isolation from human cells."

Scientist Deutsches Krebsforschungszentrum (DKFZ)

sparQ PureMag Beads

"very good product for NGS Library purification and size selection"


sparQ PureMag Beads

“I used the sparQ PureMag beads for mRNA purification after in vitro transcription. The sparQ beads demonstrated an excellent recovery (~98%) and could be used for size selection of the desired mRNA product. Highly recommended."

Postdoctoral Fellow Dana Farber Cancer Institute

qScript XLT One-Step RT-qPCR ToughMix

"qScript XLT One-Step RT-qPCR ToughMix is an easy kit that contains all the reagents needed for the master mix in one tube. The only components I added were my primers, probe and nuclease free water. The protocol is short and user friendly."

Senior Research Engineer Umeå University

sparQ PureMag Beads

"Very easy to use and really good recovery yield."

You Chen | Biologist BATJ, Inc

repliQa HiFi ToughMix

“Speed of reaction was outstanding, and produced strong bands of the expected size. Looking forward to using this product to prep our 16S rRNA gene libraries.”

Dr. Blake S. UES Dayton

AccuStart II GelTrack PCR SuperMix

'What I like about the kit is the ease of use and the rapidity to get the result with the Gel Track option. Compared to my home-made kit, I save a lot of time, and the stability of the DNA of lysed worms is better'.

Researcher IGBMC France

repliQa HiFi ToughMix

"Very fast. Almost didn't have time to prepare the next step in my protocol!"
