About This Product

OnDemand Kits are Real-Time PCR assays which we have the capability and capacity to design and develop. They are for ‘hotspot’ target organisms which have particular importance in their individual areas of interest and therefore we understand the importance of developing an assay. The OnDemand Kits can be developed on request and to meet your specific requirements meaning you will be provided with an assay which is of the highest quality and which works for you.

We offer specific qPCR assay development including primer/probe design, PCR mix optimization and assay development to ensure a very effective qPCR reaction. We have already developed a huge range kits as part of our ever expanding genesig catalogue. This service allows for the combination of bioinformatic design and development, in conjunction with laboratory testing and evaluation, to provide personally designed primers to match your exact needs and ensure high levels of sensitivity and specificity.

Upon request of development, one of our expert team members will be in contact shortly to completely understand any specific requirements you may have (incl. exclusivity criteria, etc), and they are happy to talk you through the whole process.

A preliminary investigation of the targets below suggest these organisms can have an effective qPCR assay being developed which would match our high performance criteria of specificity, sensitivity and efficiency.

If you are interested in any of these OnDemand Kits or wish to have a custom kit developed please check out the purchasing section below, or alternatively contact us via email: enquiry@primerdesign.co.uk or telephone: +44 (0)2380 748 830.


About / Technical

Our standard assay formats include Double-Dye cleavage probe (e.g. TaqMan® probes) or as primer only kits for use with SYBR green chemistry. If you require something more alternative or sophisticated, please do not hesitate to get in contact to enquire about its feasibility.

Catalogue No.

When ordering an OnDemand Kit, you firstly need to order a Feasibility Report, either before or during the kit development. This is a complete bioinformatic identification of the target regions which are totally specific to your requirements. Below are those two catalogue nos. required.

  • Feasibility Report: OnDemand-Feas
  • Design & Development (150 reaction kit): OnDemand-Dev

Process Outline

If you are interested any of the organisms below, or on any organism not listed below or in our catalogue, the process is as follows:

  • Download the Design Request Form above, or alternatively this can be emailed on request
  • This will help us understand the specific design requirements and specifications
  • Attach the form and email us on enquiry@primerdesign.co.uk
  • Following receipt of the completed form, our expert Research & Development team will review the request and we aim to respond within 1 working day
  • The service timelines, costings and development process details will be supplied

N.B. If you do not understand the Design Request Form or process, please feel free to get in contact us.



What do you get at the end of an OnDemand Kit Development?

  1. Validated, optimized and effective qPCR kit
  2. Product datasheet (incl. anchor nucleotide)
  3. Feasibility report
  4. Handbook

How long does the kit development take?
It should take 4-6 weeks per kit for design and development.

Can you order recurrent kits of the same design?
Absolutely, with significant cost reduction and dispatched with days.

What info do you need to design my kit?
Typically a gene name, species, and the NCBI accession number is required.

I’m working on an unusual species. Can you still help?
Yes. If you are working on an unusual species then we will check that good quality sequence data is available. If not we may be able to work from sequence data from a closely related species. Once synthesized, we can then validate on cDNA sent in by you, or if that is not possible then we will work on a synthetic version of the amplicon to validate the performance of the primers.

I’m working on a virus/bacteria/pathogen species. Can you design primers for these?
Yes. We have over 600 genesig pathogen detection kits already available. If your pathogen of interest is not in the list we can develop a new kit for you from scratch. You can check for your target here.

What qPCR machine(s) will these kits work on?
Easy Kit Format: Designed for optimum performance with the genesig q16 and only recommended to be used with this platform. Advanced Kit Format: These kits are designed to be open platform and will work perfectly on any qPCR machine.

How efficient is the priming of your kit?
We guarantee an efficiency of greater than 90%. 

Are your kit primers intron spanning?
Not always: As standard we will design the very best possible primers for the organism of interest regardless of intron/exon boundaries. We do not design primers to be intron spanning as standard as this is restrictive and the most efficient location for the primers may not be on an exon-exon junction. However, if you require your assays to span an intron please let us know and we will design primers to accommodate your request. If detection of gDNA is a concern we recommend the use of Precision DNase to remove contaminating gDNA from your RNA.

Is the kit guaranteed to be specific?
Yes. Thorough analysis is carried out during the design phase to ensure specificity to the target. But the gold standard test is carried out in our wet laboratory where we prove specific amplification of a single product on biologically derived cDNA or synthetic template.
