It is important to ensure that testing services meet applicable regulatory standards necessary to support investigational new drug (IND) applications, the clinical development life cycle, and commercialization. However, monitoring and — when possible — anticipating the ever-changing regulatory landscape is a challenge. Yet, the failure to do so can negatively affect both the cost and time needed to move a product from development through to commercialization. This article describes BioReliance’s position concerning anticipated regulatory changes over the next three to…

Both industrial and research scale protein purification require the development of superior procedures for increasing recovery yields. This places an emphasis on maintaining proteins in fully reduced states to solubilize inclusion bodies, while increasing the recovery of active proteins through improved protein-folding technologies. These concerns have a common theme: the ability to maintain the disulfide bonds in the protein in a sufficiently reduced state so as to facilitate correct folding while simultaneously avoiding protein aggregate formation. Dithiothreitol (DTT) is still…

Vaccine engineering, antibody quality screening, and glycosylation profiling processes can generate large quantities of protein samples that must be analyzed in a timely manner. Generation of high-quality data and rapid, quantitative analyses are mandatory to determine next steps. Although still heavily relied upon, sodium dodecyle sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is labor-intensive and only semiquantitative, and its throughput capacity is limited. Quantitative analysis techniques such as capillary electrophoresis (CE) and high-performance liquid chromatography (HPLC) do not provide the throughput necessary…

Successful cryopreservation of hematopoietic progenitor cells (HPC) depends on a number of factors: biopreservation media, freezing rates, and storage using sterile, cryogenically durable storage bags. Cell-Freeze® cryogenic storage containers are 510(k) cleared for storage, preservation, and transfer of hematopoietic progenitor stem cells (HPCs). These bags are made from a unique polyolefin film that offers excellent durability while remaining flexible when stored at ultralow temperatures (−196°C). Their proprietary membrane port design offers thinner walls for increased flexibility, and an industry-standard label…

          The standard cell line development pathway at many contract service organizations is based solely on selecting clones by growth and productivity with little or no analytical characterization of the expressed protein. The use of protein analytics to support selection of clones that match desired product quality is important for second-generation processes and will be of utmost importance for biosimilar development. CMC Biologics performs sophisticated protein characterization using state-of-the-art analytical equipment combined with our robust cell…

As single-use systems (SUS) continue to be incorporated throughout bioprocess manufacturing, a wider range of solutions and flexibility is being requested of the connections currently used in single-use systems. Colder Products Company, the leader in single-use connection technology, has been listening to the trends in the marketplace and has responded by expanding its product offering to incorporate a wider range of connections options for the single-use market. AseptiQuik® DC is the first all-in-one sterile connection technology to offer both a…

In the development of a new biological product, it is important to remember that a successful R&D development project needs to be converted from a bench-scale concept to a bioproduction platform. This process development stage requires identifying ways to increase cell numbers to meet annual dosage demands, as well as to minimize direct contact with the cell product by developing a closed system for all culture manipulations. identifying a bench-scale platform that can scale to CGMP production scale eases the…

Product recovery is a lengthy and costly procedure consisting of centrifugation and depth filtration steps to remove the cells (clarification), followed by multiple cycles of packed-bed chromatography that bind and separate the target molecule from cell culture medium components (capture). The Rhobust® Technology is a second generation expanded-bed adsorption (EBA) technology that provides an elegant solution to using multiple process steps by combining clarification and product capture into one single step in the first downstream process unit operation. The Rhobust®…
