Our Story

We Built the Platform Cell Therapy Needed to Scale

01We Saw the Bottleneck

Cell therapy was moving from academic breakthroughs to life-altering cures made at scale — and cost-effective, reproducible manufacturing was the bottleneck. We resolved to invent the solution: Vertical-Wheel Technology.

02We Built for Cells’ Unique Needs

Existing platforms designed for monoclonal antibodies production would not provide the gentle, homogeneous environment needed for shear-sensitive cell therapy product development and manufacturing where the Cell is the Therapy.

03Our Mission Goes Beyond Hardware

To successfully bring live-saving cell therapies to market, we would have to invent solutions to our customer's problems before they even became aware of them.  Innovative, novel solutions would have to be married to world-class service and support to fully realize the benefits of those solutions.

Message from Our Leadership

In Our Own Words

While our primary target is drug manufacturers, the end goal has always been about improving patient outcomes.

We develop innovative single-use bioreactors that enable cell therapies to be produced in larger volumes with compressed timelines. Our mission is to enable researchers to develop cell therapy drugs that combat chronic conditions like cancer, diabetes, and heart failure.”

Dr. Brian LeeCTO and Founder, PBS Biotech
At PBS Biotech, we believe breakthrough science only matters if it can be manufactured reliably, consistently, and at scale.

Our mission is to help cell therapy innovators bridge the gap between promising research and commercial reality, accelerating the path from discovery to patient impact.

Commitment to Quality

Built to Carry Your Process Into the Clinic

Every system, vessel, and service we deliver is governed by one quality system, because the process you validate on our hardware has to hold up under audit.

ISO-certified Quality System

Design, manufacturing, service, and document control all run under one certified quality management system.

21 CFR Part 11 Support

Control software and records are built to support Part 11 compliant electronic records and signatures in regulated production.

Controlled-environment Manufacturing

Single-use vessels are produced and packaged under clean-room controls, then released against documented specifications.

A Dedicated Quality Organization

A standing QA/QC team owns supplier qualification, incoming inspection, CAPA and change control, and supports your audits.

Certificates, quality manuals, and audit documentation are available on request.
