Rapid Cell Line Development with Integrated Protein Analysis

          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…

Eshmuno™ Resins for Biochromatography

          Eshmuno™ is a new and unique family of ion-exchange resins that are designed specifically for highly productive downstream bioprocessing.

New Protein G Biosensor Brings “Out-of-the-Box” Detection of Diverse Mammalian Antibodies

Today’s antibodies are sourced from a diverse set of mammalian hosts whose isotypes have different affinities for protein A and protein G. ForteBio’s new protein G biosensor provides an “out-of-the-box” solution for direct quantitation of the mammalian immunoglobulins that do not bind to protein A. Readings can be performed in buffer, chromatography eluents, conditioned medium, and cultured lysates using a convenient 96- or 384- well microplate format. Assay parameters can be adjusted to detect concentrations from 0.05 µg/ml to 2,000…

Biases in the Bacterial Endotoxin Test

          The bacterial endotoxins test (BET) is unique because of its biases. Several biases in the BET are caused by the variability of standard endotoxin dilutions and the methodologies of the Limulus amebocyte lysate (LAL) test. The purpose of this study is to clarify those biases.   Bias from the Standard Endotoxin Dilutions   Operators for the BET often encounter variability of the potency in the standard endotoxin dilutions. To clarify the practical variability of the…

Ready-to-Use Solutions Speed Up MAb Bioprocessing

  Summary   Comparison of a complete MAb purification process from a 100-L cell culture volume demonstrated a 50% reduction in process time using the ReadyToProcess platform instead of traditional process equipment. The decrease was made possible by elimination of column packing and testing, membrane wetting and rinsing, system cleaning, cleaning validation, and so on. Additionally, the ReadyToProcess run required less hardware and thus generated a smaller footprint. Both chromatography steps were run on one system using disposable, exchangeable flow…
