P1 synthetic microcarriers are designed for scalable adherent cell culture, providing a fully defined and consistent surface for reliable cell attachment and expansion.
Available in both Research Grade and GMP Grade, P1 microcarriers are manufactured in line with USP <1043> guidance for ancillary materials, supporting regulated cell culture and biomanufacturing applications.
Available in Soft, Medium, and Hard stiffness profiles, P1 microcarriers can also be customised in particle size, surface charge, and coating to suit different cell types and process requirements. Their stable, non-dissolvable design is compatible with standard cell harvesting workflows.

P1 synthetic microcarriers have been evaluated in adherent cell culture using HEK293T cells across both static and bioreactor conditions.
P1 provides a stable, non-dissolvable microcarrier platform for processes where controlled surface properties and standard cell harvesting workflows are preferred.
P1 microcarriers are used in microcarrier-based cell culture where strong cell attachment and surface control are required. The positively charged surface supports adhesion of a range of cell types, including those that are more difficult to culture.
As a non-dissolvable platform, P1 remains stable throughout the culture process and can be removed using standard separation methods. The surface can also be modified or coated by the user to match specific process requirements.
P1 microcarriers can support research, process development, and GMP-grade manufacturing where traceability and quality documentation are required.
These microcarriers for cell culture are suitable for:
