What Conju-Probe does
Conju-Probe, LLC is a privately-held specialty chemistry company founded in 2013 and headquartered in San Diego's biotech cluster (10054 Mesa Ridge Ct, Suite 108). The company develops and sells bioconjugation reagents — including copper-free click chemistry reagents (DBCO, BCN, tetrazine, TCO, PTAD, cyclopropene), PEG linkers, biotinylation reagents, fluorescent dyes, ADC linkers with cleavable bonds, and specialty compounds such as steroid conjugates — for laboratory research use. Underlying capabilities rest on bioorthogonal chemistry, where reactions proceed selectively in complex biological environments without copper catalysts, and on a team of synthetic organic chemists with bioconjugate experience who design and execute multi-functional heterotrifunctional and heterotetrafunctional linkers.
The company operates a catalog sales model with per-unit pricing ranging from approximately $30 to $1,350 depending on product and quantity, paired with a custom synthesis service that includes free technical consultation on design and application. There is no minimum order requirement, payment terms are net 30 days, and orders are accepted via phone, fax, mail, and email. Internationally, Conju-Probe distributes through at least eight regional channel partners across South Korea, Japan, China, and Germany. Customers are segmented horizontally across academic and industrial life science researchers, pharmaceutical and biotech companies developing therapeutics and ADCs, and diagnostics developers building imaging and assay reagents.
Conju-Probe is a micro-organization with a reported headcount in the 1–10 range, no disclosed funding rounds, no named executive team, no issued patents or trademarks, and no public revenue figures. Its competitive position is grounded in synthesis expertise and catalog breadth across bioorthogonal chemistries rather than in formal IP or platform technology.
