Custom Assay Manufacturing Services

We work with you to identify your needs to give your reagents and components for your testing

Gold conjugates - A wide range of custom services for conjugating antibody, antigen, or DNA oligo to high quality gold nanoparticles through classical adsorption approach and/or covalent reaction. The antibody or antigen of interest can be provided or selected from Bio-Techne extensive list of paired antibodies, antigens, and other proteins.

Test strips or dipsticks  - Bio-Techne offers custom stripping of antibody, antigen, or other capture agents to lateral flow nitrocellulose membrane and spraying and drying the gold conjugate pads, strip assembly and slitting into the strip or dipstick and packaging based on customer’s needs.

Assay run buffer development and bottling - blocker selection, interferant and non-specific binding.
