  • Publication number: 20220340617
    Abstract: In situ Raman spectroscopy methods and systems for characterizing or quantifying a protein purification intermediate and/or final concentrated pool during production or manufacture are provided. In one embodiment, in situ Raman spectroscopy is used to characterize or quantify protein purification intermediates critical quality attributes during downstream processing (i.e., after harvest of the protein purification intermediate). For example, the disclosed in situ Raman spectroscopy methods and systems can be used to characterize and quantify protein purification intermediates as the protein purification intermediates are purified, condensed, or otherwise formulated into the final drug product to be sold or administered.

  • Publication number: 20220306686
    Abstract: High resolution affinity chromatography combining affinity resolving and affinity capture processes using a single chromatography matrix results in improved resolution between closely related molecular species and significantly enhances overall product yield for large scale commercial production of heterodimeric proteins such as bispecific antibodies. Moreover, tankage and equipment requirements are reduced via the ability to reduce salt concentration, while increasing product purity and concentration, without the need for dilution, ultrafiltration or diafiltration.
