LAMP for Molecular Diagnostics and IVD

Partner with NEB to Incorporate LAMP in your Diagnostics Products

Loop Mediated Isothermal Amplification (LAMP) is an isothermal amplification method designed to detect a target nucleic acid without requiring sophisticated equipment. LAMP provides high sensitivity (to fg or <10 copies of target) but with rapid results: reactions can be performed in as little as 5–10 minutes. Detection of RNA targets is accomplished by simple addition of a reverse transcriptase to the LAMP reaction, with RT-LAMP performed as a true one-step, isothermal workflow.


Products with unique benefits and flexibility

  • WarmStart® for easy setup – WarmStart enzymes are inactive at room temperature, and activated when the reaction is warmed above approximately 40°C.​
  • Reactions can be performed with limited resources, using a water bath for incubation and detection of results by eye, or with real-time measurement and high-throughput instruments.
  • Reagents can be purchased as assay kits or as stand-alone enzymes, master mixes and detection dye
  • Lyophilization-compatible – most master mixes and enzymes are available in custom glycerol-free formulation 
  • NEB LAMP reagents support multiple detection methods including turbidity detection, real-time fluorescence detection (when used with LAMP fluorescent dye) and end-point visualization such as colorimetric detection via a metal indicator (e.g., hydroxynaphthol blue.)

Multiple Applications 

LAMP has been proven effective for a variety of applications including:


Detection of SARS-CoV-2 

Case Study - Collaborative R&D, Leicester University 

With funding from an MRC CiC award and supported by the Leicester Drug Discovery and Diagnostics team, scientists at the University of Leicester collaborated with members of NEB’s Research Team during development of a SARS-CoV-2 assay based on reverse transcription loop-mediated isothermal amplification (RT-LAMP). This included in-depth discussion of the enzyme formulation and primers to be used in the assay.  Initial lab tests were performed using the WarmStart® LAMP Kit and WarmStart® Colorimetric LAMP 2X Master Mix. This successful collaboration led to implementation of a customised fluorescent detection assay sufficient for 10,000 asymptomatic screening test, offered to staff and students at the University of Leicester between October and December 2020. The final implemented assay was performed to a quality managed workflow with support from Leicester Molecular Diagnostics and University Hospitals of Leicester Pathology Services with positive samples feeding into the NHS England Test and Trace system (Pillar 1).

Other applications 

LAMP is suitable for use in a wide variety of amplification-based molecular diagnostic assays. Contact us to discuss your technical requirements. You can find all the Application Notes for LAMP here.



  • NEB has responded to the COVID-19 pandemic by scaling production to meet increasing global customer needs.
  • We can offer rapid and flexible in-house scale-up capabilities.
  • WarmStart® LAMP Kit (DNA & RNA) #E1700: This reagent has been incorporated into Oxford Nanopore’s LamPORE technology, a combination of LAMP with nanopore sequencing, initially implemented to provide a rapid, low-cost and scalable assay for the detection of SARS-CoV-2.

Ease of setup

  • LAMP offers ease of setup for a test that can be administered in varied settings, without the need for a laboratory.
  • Kits with primers included eases development of your commercialized product. We work with multiple UK and European service diagnostic providers to support their technology and supply them with LAMP reagents at scale.
  • LAMP primers can be challenging to design manually, and software programs are strongly recommended. We have developed the NEB LAMP Primer Design Tool to ease both design of LAMP primers and likelihood of reaction success.
