Controlled production.
Liquid-culture production under documented quality controls, batch tracking, and release criteria.
Where a selected culture becomes a defined batch.
Selection decides what to grow. Production grows it the same way twice, in quantities a field program can draw on, with a written record of what each batch is and whether it was fit to leave.
The South San Francisco facility is secured for buildout and is not operating. Nothing on this page describes production capacity in place, commissioned equipment, or output.
Liquid culture makes it produceable.
Growing the culture in liquid gives us defined batches and something a field crew can carry and apply across terrain. That is why the platform is organised around production runs instead of individually prepared material.
Controls have to be written down.
Controls that exist only as practice cannot be reviewed by a customer, an agency, or the company itself. Write them down and a reviewer can check a run against a standard instead of against somebody's recollection.
Every batch stays identifiable.
Batch tracking carries the identity established at selection forward through production, so that what was applied at a site can be traced back to what was made and when. Monitoring at step 05 is only interpretable if that thread holds.
Release is a check, not a call.
Release criteria are the conditions a batch has to meet before it can go to the field. We define them in advance so nobody has to make the call under schedule pressure.
This describes the production process the platform is being built to run. It is not a statement of installed capacity, and no output, throughput, or performance figure is claimed.
