Our Process

Processing of whole blood samples happens directly from numerous accredited clinical sites. Isolation of cells follows either sponsor-directed operative procedures or an in-house protocol, available upon request. The average cell viability across all PK4 sites and studies stands at >96%.


Each site within the PK4 Laboratory network holds a -20°C, -80°C, and LN2 freezer for storage, whether short-term or long-term. Shipping is scheduled based on client requirements.
