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.

Dr. Harry M.T. Choi

Founder & CEO

Harry Choi co-founded Molecular Instruments (MI) in 2018, serving as the CEO since its inception. Prior to founding MI, Harry was the lead researcher for three generations of HCR technology development at Caltech (v1.0 in 2010, v2.0 in 2014, v3.0 in 2018), exploiting new concepts from dynamic nucleic acid nanotechnology to overcome multi-decade challenges to multiplexed quantitative bioimaging in thick autofluorescent samples. Harry served as Director of the HCR technology resource within the Beckman Institute at Caltech from 2010–2018, supporting research labs around the world. Harry received a BS in Bioengineering with honors from UC Berkeley and a PhD in Bioengineering from the California Institute of Technology.
