About

ProbeSure Genotyping Master Mix combines class-leading performance with the most competitive prices in the market. ProbeSure Genotyping Master Mix has provided users with accurate, robust, and consistent performance for many years. It has been carefully optimised to work over a wide range of reaction volumes and sample template qualities.

ProbeSure Genotyping Master Mix is supplied at 2x concentration for convenience and is supplied with the ROX normalising dye at either high level (500 nM final concentration), low level (25 nM final concentration) or without ROX.

FAQ:

What types of probes can I use with ProbeSure Genotyping Master Mix?

Any dual-labelled probe with a fluorescent label at the 5′ end and a quencher at the 3′ end, such as TaqMan™, ZEN™ probes and BHQ® and BHQplus® probes, can all be used with ProbeSure Genotyping Master Mix.

What controls should I use for genotyping?

Negative controls are very important to establish that the amplification being seen is real. Negative controls should always be used and should consist of the buffer the DNA samples are hydrated in.

Positive controls can be included to increase confidence that the correct genotypes are assigned to the samples, though this is not necessary in all cases. Positive controls should be samples of known genotype and are generally of more use when assessing a very low frequency variant.

Can I use PACE assays with ProbeSure Genotyping Master Mix?

No, ProbeSure Genotyping Master Mix can only be used with 5′ nuclease probe-based (e.g., TaqMan) assays only. Similarly, 5′ nuclease assays cannot be used with PACE Genotyping Master Mix.

Can I dilute 3cr Bioscience master mixes below 1x to make them go further?

We have encountered customers using master mixes at final concentrations below the intended 1x. This may work in some instances. Use of any of our master mixes below (or indeed above) 1x final concentration is not recommended as it could potentially lead to erroneous results.  All our master mixes have been developed such that their components are optimal for their intended use at 1x concentration in the final reaction mix.

Which ROX concentration do I require in my Genotyping Master Mix?

We manufacture PACE and ProbeSure Genotyping Master Mixes with different ROX levels. PACE Genotyping Master Mix is available as a high ROX (500 nM), low ROX (25 nM), standard ROX (150 nM) and no ROX version. ProbeSure Genotyping Master Mix is available as a high ROX (500 nM), low ROX (25 nM) and no ROX version.

If you are unsure about which ROX level is required for your qPCR machine or plate reader, please refer to the PACE ROX Instrument Compatibility List and ProbeSure ROX Instrument Compatibility Lists, or contact 3CR Bioscience technical support support@3crbio.com and we will advise you.

Do you also offer a free assay design service for 5’ nuclease probe-based (e.g., TaqMan) assays for use with ProbeSure genotyping master mix?

No. However, 5’ nuclease assays are available from a range of manufacturers, such as IDT.

Can the ProbeSure Genotyping Master Mix be used with intercalating dyes in real-time PCR?

No. ProbeSure Genotyping Master Mix is not designed for use with intercalating dyes. We do not currently make a product specifically or this application, though it is something we’d consider if enough customers request it.

MEET OUR TEAM

Steve Asquith Managing Director
Steve began his career in the Genetics Division of GlaxoSmithKline, as part of the team establishing GSK’s high-throughput core genotyping laboratory. Steve joined KBioscience when it was first founded in 2002 and was a key driver in taking the company from a small start-up to a multi-national service laboratory, quickly growing the company’s revenue to over $7.5M p.a. Following the acquisition of Kbioscience by LGC in 2011, Steve was appointed Global Director of Operations for LGC Genomics, responsible for over 100 staff in Europe and N. America, successfully elevating the genotyping products and service business. Steve held a crucial leadership role until he left in 2016. In 2017 Steve joined forces with John Holme to create 3CR Bioscience, a new company with a mission to deliver outstanding, customer-focused genotyping products with innovation and affordability at its core.
Dr. John Holme Technical Director
John joined KBioscience shortly after it was founded, in 2003, and became Head of Technical Development, building the company's genotyping and DNA extraction product portfolio and service delivery until 2011 when it was acquired by LGC. Post-acquisition, John was appointed Head of Technical Group for LGC Genomics, in charge of all Research & Development and Technical Support activities for the company. In this role John continued to build on the high-quality products and services provided to the companies growing customer base. During the 19 years John has worked in commercial R&D, he has co-invented numerous highly successful products including PACE®, ProbeSure, KASP™, KlearKall, KlearGene, KlearAmp and KlearTaq™, creating breakthrough offerings in genotyping and extraction and generating huge revenues for the companies he has worked in. In 2017, he joined forces with Steve Asquith and started 3CR Bioscience. John is dedicated to developing outstanding, innovative genotyping products and providing the very best technical support to customers globally.
Dr. Nisha JainOperations Director
Nisha has been innovating since the start of her career at Geneform Technologies developing Iso-thermal Genotyping Technologies. Nisha joined KBioscience in 2008, as Senior R&D Scientist and key account Technical Support Scientist, developing KASP and Klearkall performance and coinventing two further versions of KASP. Nisha has more than 15 years’ experience working in molecular biology and genotyping technologies, with extensive experience in the areas of R&D, Quality Assurance and Customer Technical Support. She has technically assisted many giants of the industry with their protocol development and troubleshooting and continues to deliver high-quality support and guidance.

Jon Curtis Non-Executive Chair
After 8 years in The Royal Air Force, Jon moved to the Imperial Cancer Research Fund where he pioneered the use of ultra high-throughput genomic automation, capable of 46,000 PCRs per hour. In the 1990’s Jon joined GlaxoSmithKline, implementing a high-throughput genomics platform into their drug discovery pipeline. Whilst there he also developed acoustic mixing into compound management, becoming the gold standard across pharma. Jon developed the world’s first commercially viable 1536-well PCR plates, automated thermal & laser plate-sealer, plus automated liquid-handling & tip washing tools to reduce waste and costs. In 2002 Jon co-founded KBioscience with Phil Robinson, utilising ultra high-throughput PCR instrumentation & a suite of automation tools to create the company’s SNPline robotic platform, with a capacity of 250,000 PCRs/day. The business was underpinned by their ground-breaking patented genotyping chemistry, KASP™, which has over 10,000 scientific papers to date. In November 2022 Jon joined 3CR Bioscience acting as an advisor bringing his commercial and scientific experience to the company.
