6 terms

cell-free biomanufacturing medical

"an important validation and de-risking milestone for its cell-free biomanufacturing platform"

Cell-free biomanufacturing makes biological products — like proteins, enzymes or vaccine ingredients — by using the molecular machinery of cells removed from living organisms, rather than growing whole cells. Investors should care because this approach can speed up production, cut costs and reduce contamination risk, making supply chains more flexible and potentially changing how quickly and cheaply biotech products reach the market.

downstream processing technical

"operating the reaction, downstream processing, and analysis independently"

Downstream processing is the set of manufacturing steps that take place after a biological product is made, where the target molecule is separated, cleaned and turned into a stable, usable drug or vaccine form. It matters to investors because these steps determine how much usable product is recovered, how quickly regulators will accept it, and how costly manufacturing will be—like turning raw crops into packaged food, small losses or contamination can sharply affect supply, timelines and profits.

pharma-grade medical

"ultimately producing more than 500 grams of pharma-grade N-trans-caffeoyltyramine"

Pharma-grade describes drugs, raw materials or ingredients manufactured to the purity, quality and documentation standards required for use in medicines and clinical testing. Think of it like food-grade versus industrial-grade: pharma-grade parts are cleaned, tested and certified so they won’t introduce safety or efficacy problems. For investors it signals lower regulatory and supply risk, greater likelihood of approval or sale to healthcare customers, and often higher pricing and margin potential.

conversion rate technical

"the analysis showed over a 99% conversion rate"

Conversion rate is the proportion of items, people or contracts that take a desired action out of the total possible — for example the share of website visitors who make a purchase, or the number of convertible bonds that are exchanged for shares. Investors care because it measures how effectively a business or financial instrument turns opportunity into real outcomes, like sales or share issuance, which directly affects revenue, cash flow and ownership dilution.

biocatalysis medical

"I’ve performed a lot of cell-based enzymatic biocatalysis over the years"

Biocatalysis is the use of natural catalysts—usually enzymes or whole cells—to speed and steer chemical reactions in making molecules like drugs or specialty chemicals. Think of enzymes as skilled workers on an assembly line that can make the process faster, cleaner and more precise than traditional chemistry, which can lower production costs, reduce waste and create competitive advantages or regulatory benefits that matter to investors assessing manufacturing efficiency and long-term margins.

pilot scale technical

"successfully ran eXoZymes' technology at pilot scale and achieved results"

Pilot scale is a small, controlled version of a production process used to test whether a product and its manufacturing method work reliably before investing in full-scale facilities. Think of it as a test kitchen or a mini factory where engineers check yields, costs, and unexpected problems; successful pilot runs reduce technical and financial risk and give investors a clearer sense of timelines, likely production costs, and remaining obstacles to commercial sales.

LOS ANGELES, CA / ACCESS Newswire / March 18, 2026 / Today, eXoZymes Inc. (NASDAQ:EXOZ) ("eXoZymes") - a pioneer of AI-enhanced enzymes that transforms abundant feedstock into valuable nutraceuticals and novel medicines - announced an important validation and de-risking milestone for its cell-free biomanufacturing platform: An independent partner, Cayman Chemical, successfully ran eXoZymes' technology at pilot scale and achieved results consistent with - and in some cases exceeding - earlier internal runs.

Using eXoZymes' tech transfer package, Cayman Chemical advanced the protocol from a one-liter setup to a 100-liter pilot run, operating the reaction, downstream processing, and analysis independently. During the run, the team encountered real-world conditions - including pH variation and precipitation - which often cause enzyme-based processes to fail. Despite this, the reaction continued to perform reliably and delivered strong results, ultimately producing more than 500 grams of pharma-grade N-trans-caffeoyltyramine (NCT) at 99.6% purity, a result that is difficult to obtain in biomanufacturing without extensive purification steps. Additionally, the 99% conversion of feedstock to end product highlights a level of efficiency that is challenging to achieve and maintain in traditional biomanufacturing.

For Cayman Chemical, the outcome stood out based on prior experience as highlighted by Patrick Westcott, Director of Catalog Chemistry Production at Cayman Chemical: "I've performed a lot of cell-based enzymatic biocatalysis over the years; it is a critical component of what we do at Cayman. One common aspect of this work is a drop in efficacy during scale-up. Anytime you move up in scale orders of magnitude, a process changes enough that it is considered a different process altogether."

Westcott, continues, "During the experiment, from the first sample that we took the analysis showed over a 99% conversion rate. There was some concern because I thought that that maybe was a little bit too high. So, we decided to take a second sample to see if it maintained a similar conversion rate. And we were a little surprised to find out that we actually did achieve this 99% conversion in our first 100-fold scale up of their process. That was very much an aha moment for us!"

"This pilot run is an important validation of our cell-free platform, demonstrating that it performs reliably at scale and delivers strong results in the hands of an external partner. The fact that this project reached pilot scale in less than a year underscores our ability to move R&D at a disruptive pace - and just as importantly - it meaningfully reduces platform execution risk by showing that our technology can be transferred and operated successfully beyond our own labs." states Chief Commercial Officer at eXoZymes, Damien Perriman, and continues, "With more than 500 grams of pharma-grade NCT now available from this run, we are actively engaging partners interested in evaluation, formulation development, and potential commercialization."

Formulation can be shipped to partners
