Harvest RC Advanced Harvesting Technology:
The first step of the separation and purification process of recombinant biotherapeutic drugs is to harvest the cell culture solution containing the target product. Traditional operation methods of this unit involve depth filtration, centrifugation, and membrane filtration. The separation and purification principles of these technologies are mostly based on the density and size differences of particles. With the continuous improvement of cell culture technology, cell density and product titer are also increasing. However, how to achieve efficient, stable and large-scale cell culture fluid harvesting is quite challenging.
Harvest RC Chromatographic Clarifier is a fibrous product with anion exchange (AEX) chromatography function, whichcan effectively separate cells, cell debris, and DNA from the harvest solution containing the target product. It combines functionalized polypropylene fiber with quaternary ammonium group (Q) with 0.2μm PES membrane, which provides a predictable scaling from drug discovery to manufacturing.
Harvest RC Chromatographic Clarifier is aninnovative and fully synthetic single-stage single-usechromatographic clarification solution. This new generation of harvesting and clarification technology can streamline the upstream processes by replacing centrifugation and/or depth filtration steps while improving the yield of monoclonal antibodies (mAb).
Key Features of Harvest RC:
-
The capsule type can make the product recovery rate reach 95+%;
-
Replacement of primary, secondary, and guard membrane clarification stages;
-
Based on stable clarification and cell loading capacity, the product specifications required from drug discovery to manufacturing can be predicted;
-
Capsules fit into laboratory to manufacturing scale workflows;
-
Lower total cost of manufacturing compared to centrifugation and depth filtration;
-
No need for cleaning after use, which means there is no need to use online cleaning CIP agents that are corrosive or potentially toxic;
-
Lower consumption of buffer and water compared to depth filtration.
Harvest RC Innovative Design and Performance
Harvest RC Chromatographic Clarifier encapsulates innovative synthetic fibrous anion exchange (AEX) chromatography media and a 0.2 µm polyether sulfone (PES) membrane. This enables a single-stage clarification process of low to high-density cell culture (>40×106cells/ml) with high recovery, and high fidelity of soluble and insoluble contaminant separation.
Cells are bound inside the media by electrostatic charge interaction with the AEX chromatographic fibers. This results in the efficient retention of large and small particulates without developing a surface cake layer. The media can also remove soluble impurities which results in cleaner effluent than centrifugationor depth filtration.

Harvest RCPerformance Data
mAb product recovery
Harvest RC Chromatographic Clarifier is a single stage chromatography solution that effectively clarifies Chinese Hamster Ovary (CHO) harvest cell culture fluid (HCCF) across a wide range of cell densities, packed cell volumes (PCV), and turbidities.
3M Harvest RC Chromatographic Clarifier capsules consistently provide >95% mAb product recovery for high cell density cultures from the laboratory to the manufacturing scale.
Turbidity reduction
Harvest RC Chromatographic Clarifier provides consistent separation of cells, cell debris, and DNA from the target protein. Clarified cell culture fluid (CCCF) has low turbidity, typically <15 NTU. Additionally, consistently low acidified turbidity of CCCF indicates significant reduction of DNA in the clarified material. Low acidified CCCF turbidity is a measure of the amount of DNA present in the cell culture fluid.
Scalability
Harvest RC Chromatographic Clarifier capsules scale linearly across laboratory, pilot, and manufacturing scales. Fibrous chromatographic clarification assures scalable performance from discovery to manufacturing scales. Performance is consistent from laboratory capsules (BC4 and BC25), scale-up capsules (BC340 and BC1020), to production capsules (BC2300 and BC16000) within ±20% of BC25 throughput.
Throughputs of Harvest RC Chromatographic Clarifier capsules are scaled by area based on packed cell volume.
Cell loading capacity
Harvest RC Chromatographic Clarifier utilizes advanced Q functionalized fibrous chromatography media to achieve single-stage clarification, enabling predictable and consistent cell loading capacity for CHO cell culture fluid for a wide range of packed cell volumes.
Cell shear
The low-pressure chromatographic clarification relies on charge rather than size or density. This results in minimal cell shear compared to conventional depth filtration processes even at medium and high cell densities. Cell shear was evaluated by lactate dehydrogenase (LDH) assay.
Robust sterile filter protection
Due to the highly effective chromatographic reduction of soluble and insoluble contaminants, Harvest RC Chromatographic Clarifier enables efficient clarification, and is capable of effective protection of final sterilizing grade membrane filter down to 0.1 µm pore size.
