Why LGC, Biosearch Technologies?

Let our experience be your asset.

Learn how our GMP and commercial services group can work with your development teams to design and deliver individual custom, critical oligonucleotide components or fully finished diagnostic kits. Biosearch Technologies provides synthesis, formulation and packaging to accelerate assay development from conception to commercialisation. We can satisfy all your dye selection, oligo modification and special manufacturing demands for high quality IVD oligo components.

Trusted oligonucleotide component manufacturer for diagnostic assays

With over 20 years of experience in oligonucleotide synthesis, chemistry manufacturing and instrumentation, Biosearch Technologies has established itself as a reliable business partner for providing oligo components for in vitro diagnostic suppliers. Our state-of-the-art laboratories, superior quality reagents, ISO 13485 compliant standards and fully customisable, yet consistent production processes, make Biosearch Technologies the partner of choice for diagnostic test manufacturers.

Benefits and features that Biosearch Technologies has to offer:

  • Simplify technology licensing requirements
  • Choose from the largest selection of oligonucleotide modifications available 
  • Minimise large and multiple capital investments 
  • Scalable manufacturing tailored to your needs
  • Rely on Biosearch Technologies’ extensive experience across all phases of manufacturing
  • Manage regulatory constraints
  • Accelerate the development of your molecular diagnostic project 

Project management

Biosearch Technologies has a project management team dedicated to providing personal consultation and support through every phase of your diagnostic product. For each product, we can:

  • Discuss product details such as sequences, purity, synthesis scales and delivered amounts, chemistry, manufacturing and QC specifications, regulatory requirements, lead time, IP, etc.
  • Support your quality and regulatory staff with FDA submissions by assisting with risk assessment, documentation, stability studies, etc.
  • Provide help with oligonucleotide design, assay development, or application usage
  • Give regular updates on the current production status

Dyes and quenchers

Since our introduction of the Black Hole Quencher™ (BHQ™) dyes in 2000, BHQ dyes have become the dark quencher of choice in the DNA marketplace. Other proprietary dyes include the CAL Fluor™ and Quasar™ dyes, which are vibrant, high performing fluorophores designed to perfectly complement the BHQ dyes. Biosearch Technologies can also manufacture many other dyes such as FAM, TET, HEX, JOE, etc., to supply any combination of fluorescence-quenched probes.

Biosearch Technologies offers flexible and different levels of licensing programs that can be tailored to the terms of your project. Partner with Biosearch Technologies so you can consolidate your oligo supply and dye licensing needs. Contact licensing@biosearchtech.com with any related questions.

GMP Product Development


State-of-the-art production facilities

A vertically integrated structure allows Biosearch Technologies to precisely control the raw materials and manufacturing process, reducing costs and turnaround time. These advantages and Biosearch Technologies’ ability to manufacture diagnostic components containing BHQ dyes make use the ideal partner for medical device development.

DNA Synthesis
IVD Purification Lab

Our synthesis skill set includes:

  • Fluorogenic probes and primers to fuel various platforms such as: real-time qPCR thermal cyclers, Luminex®-based systems and isothermal amplification
  • Synthesis scales ranging from 25 nanomoles to several millimoles
  • Unmodified oligos as long as 200 bases
  • Synthesis of oligos with a vast selection of modifications, RNA, DNA-RNA hybrids, and other complex and rare specialty bases

Whether you need HPLC purified oligos mixed and normalized in custom buffers, or bulk oligos, Biosearch Technologies can deliver. We offer a variety of purification options and highly customisable formulation and delivery specifications tailored to your product requirements.


Quality management

The Biosearch Technologies Quality Management System (QMS) within IVD oligo production is designed for compliance to ISO 13485:2016 and the requirements of 21 CFR Part 820 (as applicable). Our QMS documentation results in reproducible components that consistently meet the needs of our clients. Our production batch records provide full process traceability and undergo systematic scrutiny during Quality Assurance review and release.
