Abstract
In this study, we investigated the effect of adenosine and its derivative cordycepin on the production yield of a recombinant human monoclonal antibody (adalimumab) in two commonly used Chinese Hamster ovary (CHO) cell lines that have different gene amplification systems, namely CHO-DHFR- and GS-CHO knockout (GS-KO CHO) cells and that were grown in batch culture, with and without glucose feeding. The results showed that adenosine suppressed the cell growth rate and increased the fraction of cells in S phase of the cell cycle for both CHO cell lines. Different concentrations and exposure times of adenosine feeding were tested. The optimal yield of adalimumab production was achieved with the addition of 1 mM adenosine on day 2 after start of the batch culture. Adenosine could significantly improve antibody titers and productivity in both CHO cell lines in cultures without glucose feeding. However, upon glucose feeding, adenosine did not improve antibody titers in CHO-DHFR- cells but extended culture duration and significantly increased antibody titers in GS-KO CHO cells. Therefore, adenosine supplementation might be useful for antibody production in GS-KO CHO cells in medium- to large-scale batches. In case of cordycepin, a derivative of adenosine, CHO-DHFR- cells required higher concentration of cordycepin than GS-KO CHO cells around 10 times to display the changes in cell growth and cell cycle. Moreover, cordycepin could significantly increase antibody titers only in CHO-DHFR- cell cultures without glucose feeding.

Abstract
Antibody titer and viable cell density (VCD) are two important parameters that need to be closely monitored during the process of cell line development and manufacturing of therapeutic antibodies. Typically, determination of each parameter requires 10–100 μL of supernatant sample, which is not suitable for small scale cultivation. In this study, we demonstrated that as low as 2 μL of culture supernatants were sufficient for the analysis using UV-Vis spectrum assisted with partial least squares (PLS) model. The results indicated that the optimal PLS models could be used to predict antibody titer and VCD with the linear relationship between reference values and predicted values at R2 values ranging from 0.8 to > 0.9 in supernatant samples obtained from four different single clones and in polyclones that were cultured in various selection stringencies. Then, the percentage of cell viability and productivity were predicted from a set of samples of polyclones. The results indicated that while all predicted % cell viability were very similar to the actual value at RSEP value of 6.7 and R2 of 0.8908, the predicted productivity from 14 of 18 samples were closed to the reference measurements at RSEP value of 22.4 and R2 of 0.8522. These results indicated that UV-Vis combined with PLS has potential to be used for monitoring antibody titer, VCD, and % cell viability for both online and off-line therapeutic production process.
