BioAssay Works assay-development services allow companies to quickly enter a rapid test market with a minimum investment of resources and time. Our services range from a simple assay-feasibility project to a full-scale development project, including custom manufacturing.
We specialize in developing rapid assays utilizing our deep expertise in gold nanoparticles, including:
- Lateral-flow assays (single/multiple analytes)
- Flow-through systems
- Qualitative assays (yes/no)
- Semi-quantitative assays (reader devices)
We have experience working with a large variety of sample types such as saliva, whole blood, serum, tears, urine, feces, biopsy fluids, cell culture supernatant, bacterial broth, etc. and have developed assays for both antibody and antigen detection.
Our Experience Counts
Since 2005, we have successfully developed and manufactured dozens of custom rapid assays for a variety of clients for:
- Human medicine (biomarkers and pathogens)
- Veterinary medicine (infections, fertility)
- Food industry (allergens, bacteria, toxins)
- Pharmaceutical (vaccine production monitoring)
- Industrial monitoring devices
- Biodefense (biowarfare agents)
- Environmental (contaminants)
- Nucleic acid tests
Many of these assays deliver lab-based assay sensitivity in a rapid assay suitable for field or non-laboratory use. We are proud of our track record of developing successful rapid assays for our clients. Let us put this experience to work for you.
Our Technology Makes a Difference
We have four core technologies that we use to help our customers bring lab-based assay sensitivity to point-of-care, rapid assays:
- Ultra-sensitive, concentrated gold-sols that do not use the traditional boiling, reduction process to manufacture the nanoparticles and result in a 15 – 100 O.D. concentrated gold-sol, the foundation for ultra-sensitive assays.
- The unique properties of our concentrated gold nanoparticles enable us to covalently conjugate antibodies, antigens and other ligands. This ensures an optimized and very stable gold conjugate.
- A proprietary gold-ribbon drying process that enhances the release of the gold conjugate from the conjugate pad contributes to an increase in assay sensitivity.
- Our patented C-FLAT® lateral-flow assay platforms (US Patents #7,910,381 and #7,344,893) enable increased assay sensitivity.
Clients are in control of each assay-development project and can choose to continue or end the project at any time. Each project is thoroughly documented to help ensure assays can be reproducibly manufactured at the conclusion of the project.
Every project is unique, but most projects follow our three-stage process. Absent an early determination of infeasibility, most assay-development projects proceed to completion.
|Stage 1 - Feasibility||This stage quickly provides insight into whether a rapid test has a reasonable chance for success.|
|Duration||Normally, 6-10 weeks|
|Client Decision||Proceed to Development, perform additional feasibility work, or end project.|
|Stage 2 - Development||A working prototype assay is developed. Initial optimization of various assay components (membrane, gold conjugate pads, wicks, concentrations of assay reagents) is performed.|
|Duration||Normally, 6-12 weeks|
|Deliverables||Development report detailing assay design, limits of detection, assay duration, and results from testing samples. 50-100 assay prototypes for client use|
|Client Decision||Proceed to Optimization stage, perform additional development work, or end project.|
|Stage 3 - Optimization||The prototypes produced in the Development stage are further optimized and will reflect the insight gained from your evaluation. The process for assay manufacturing is fully documented in preparation for production by BioAssay Works or transfer of non-proprietary components to you for manufacturing.|
|Duration||Normally, 6-12 weeks|
|Deliverables||Optimization report detailing any optimization done to the assay, SOPs for the manufacture and quality control of rapid assays.|
|Client Decision||Who will manufacture test (BioAssay Works, client, third party)?|
