Our Mission

To create a new era in which the building blocks of life are quantified at high resolution in the anatomical context of intact tissues.


Our Products and Services

Molecular Instruments® (MI) designs and synthesizes kits for multiplexed, quantitative, high-resolution bioimaging in academic research, drug development, and clinical pathology and diagnostics. MI offers custom assay design and development services for life sciences and pharmaceutical laboratories and companies, as well as nucleic acid sequence design and analysis services for agricultural and veterinary enterprises. 

Our Technology

Our hybridization chain reaction (HCR) technology introduced the concept of conditional nucleic acid self-assembly — a foundational principle for the field of dynamic nucleic acid nanotechnology. HCR imaging technologies open a new era for in situ hybridization (ISH) and immunohistochemistry (IHC), enabling simultaneous multiplexed, quantitative, high-resolution RNA and protein imaging in the anatomical context of intact tissues, with 1-step, multiplexed, quantitative, isothermal, enzyme-free HCR signal amplification for all RNA and protein targets simultaneously.
