The Biomanufacturing Bottleneck

The cold-chain can still be a major source of loss.

Cryopreservation is central to the storage and distribution of advanced therapy medicinal products, including engineered immune cells, stem-cell-derived materials, and other cold-chain-sensitive biologics. However, freezing and thawing can introduce severe cellular and formulation stress.

Standard protocols often depend heavily on DMSO and related cryoprotective strategies to suppress lethal ice formation. While effective, higher cryoprotectant loading can also contribute to toxicity, osmotic stress, workflow complexity, and added pressure on post-thaw handling.

Temperature fluctuations during storage, transport, or thaw can also trigger ice recrystallisation, increasing the risk of mechanical damage, membrane disruption, and reduced post-thaw recovery of the intended therapeutic dose.

The Engineering Approach

Reducing damage at the ice interface.

IBP Ventures evaluates ice-binding proteins that act directly at the ice-water interface, providing a different mechanism for managing freeze damage during the cryopreservation cycle.

Recrystallisation inhibition Candidate proteins are assessed for their ability to reduce crystal growth during thawing and cold-chain excursions.
Potential reduction in DMSO reliance More effective interfacial control may support future formulation strategies that reduce dependence on highly loaded bulk cryoprotectants.
Support for viable recovery The objective is to reduce freeze-related damage and assess whether post-thaw recovery and consistency can be improved in relevant workflows.
Why It Matters

Protecting the integrity of the therapeutic dose.

In cell therapy manufacturing, post-thaw losses are not just a storage issue. Reduced viability or recovery can affect dose consistency, downstream handling, and the practical performance of a valuable therapeutic product.

Improving cryopreservation is therefore not only about long-term storage. It is about preserving intended potency, supporting functional recovery, and reducing avoidable stress on clinical or manufacturing teams handling sensitive material after thaw.

Commercial Relevance

A focused evaluation pathway.

IBP Ventures offers defined feasibility pilots to assess whether ice-binding proteins can integrate into and improve specific cell therapy or biologics cryopreservation workflows.

ATMP and biologics focus Evaluate workflows where post-thaw recovery, viability, or DMSO-related constraints may be affecting product performance.
Decision-oriented output Generate specific data on post-thaw recovery, viability, and workflow compatibility before larger development work.
Formulation compatibility Assess technical fit within existing cryopreservation, excipient, and handling frameworks.
Why This Matters in Practice

Small improvements can have outsized operational value.

In high-value cell therapy workflows, even modest improvements in post-thaw recovery, viability, or robustness may translate into better batch consistency, less process waste, and lower pressure on tightly controlled downstream handling.

For therapy developers and manufacturing teams, the key question is not whether cryopreservation is already functional, but whether it could perform more reliably in a way that is technically meaningful and commercially justified.

Feasibility Logic

A practical first step before larger commitments.

The objective of a feasibility pilot is to determine whether the ice-binding protein approach merits further formulation work, scale-up attention, or integration into a more formal development pathway.

Defined scope Focus on one workflow, one material type, and one practical performance question at a time.
Evidence before expansion Use early technical evidence to support a clearer go / no-go decision.
Commercial realism The purpose is not open-ended experimentation, but decision-grade output relevant to a real bioprocess.
Wider Cryopreservation Context

Where this fits within our broader cryopreservation capabilities.

While this page focuses on cell therapy and biologics, the same underlying challenge of freeze damage, recrystallisation, and post-thaw recovery also appears across other high-value biological systems.

Cell therapy and biologics

Sensitive therapeutic cells and formulations where freeze–thaw recovery, viability, and handling robustness are commercially important.

IVF and reproductive workflows

Embryo and oocyte cryopreservation where post-thaw survival and warming-stage damage are critical constraints.

Biobanking and research preservation

Sample storage workflows where reduced preservation loss and improved long-term consistency may be valuable.
