CrisBio is the name given to the expression platform, a technology first worked on at Algenex from 2005 and carried into a separate company through a 2022 spin-off, followed by a 15 million euro Series A the next year. Catalog enzymes currently include T4 DNA Ligase and Thermostable Inorganic Pyrophosphatase, both aimed at in vitro transcription workflows. Custom projects open with a three-month proof of concept covering gene synthesis, tailored baculovirus production, expression in inoculated chrysalises, and a purification strategy reported with preliminary yield, purity and concentration; scaling up for industrialization takes a further four to six months and steps from one liter through ten liters to batches of 50 to 400 liters. Manufacturing sits in the Bizkaia science and technology park at Derio, near Bilbao, where 2,300 of 4,000 square meters are given to production under GMP guidelines, with a separate R&D laboratory in Madrid.
