Prior to analysis, the samples were centrifuged and washed twice. In the present work, we describe a simple and inexpensive Bradford assay method to determine the HCP content in culture supernatants, which is referred to as residual protein content (RPC). However, in some instances sample availability is limited resulting in samples of very low concentration that require a reporter molecule that is directly proportional to the analyte present thus extending the quantifiable concentration range.

Additionally, both methods are used for cell lysis process monitoring in a recombinant Chinese hamster ovary fed‐batch process. The processes at 31 °C lasted 1.6‐ and 1.3‐fold longer compared to the experiments at 37 °C and 34 °C, respectively, until the stop criterion (viability <70%) was reached (Figure 4A,B).

Sample preparation was performed as previously described for the titer quantification.

Most of these sticky proteins are intracellular proteins.17 Hence, cell lysis leads to an increased level of these proteins in the supernatant, which increases the probability of their association to the mAb and their sticking to the chromatography resins. It was apparent that the impact of the variance of antibody determination was very small and thus did not have a significant influence on RPC estimation.

A serial dilution was then prepared from the stock ranging from 0 to 1,500 μg/mL. Linear regression was obtained for both standards.

The microplate is sealed and allowed to incubate at 37 °C for 30 minutes. Check back often for our latest additions to the Visual Abstract library! Apparently, cell lysis accounted for a maximum of 8.8% of the total produced biomass in the system (Figure 5A), whereas the HCP content reached values up to 500 µg mL−1, corresponding to 50% of total protein in the supernatant for this model process. Bovine serum albumin (BSA) (5000002; Bio‐Rad Laboratories) and IgG (Lot‐No. They will guide you through your decision process and help you select the proper equipment for your application, assist with installation in your lab, and train your staff on the use of the instrumentation.

The BSA concentration was recalculated after subtraction of the resulting absorbance value of a given IgG concentration from the total absorbance (calibrations used are depicted in Figure 2A).

Agilent cell metabolism assays detect discrete changes in cell bioenergetics in real time, providing a window into the critical functions that provide ATP, the energy that cells need for activation, signaling, proliferation, and biosynthesis. Similar to the RPC method, mean deviations (see Equation 1) from the slope k and intercept d were monitored over a time course of over 690 days (Figure 3B,C); both exhibited variation under 20%. The reaction is dependent on the amino acid composition of the measured proteins. The cell line was generated by applying the Rosa26 bacterial artificial chromosome expression strategy20 to a serum‐free adapted host cell line derived from CHO‐K1 (American Type Culture Collection [ATCC] CCL‐61). The Synergy LX Multi-Mode Reader with absorbance monochromators was used to measure absorbance at 280, 320, 900 and 977 nm in a single protocol to allow automated path length correction and protein quantification.
