Gibco Bioproduction Services (GBS) media panel Our GBS media panel consists of 5 diverse chemically defined formulations (Table 1) produced using animal origin-free components. These formulations can be further supplemented with growth factors upon request.* The Gibco CD CHO Media Test Panel Consultation Service offers rapid access to a media library along with consultative technical support for customers wishing to test and compare multiple formulations. Our experienced technical support team can help you save time by assisting you in planning your experiment and analyzing your...

These 5 formulations can be mixed to produce multiple conditions to test, depending on your resources and system capabilities (Table 2). No matter the number of conditions tested, our scientists and technical engagement team will be available at every step to assist and answer questions to help shorten your time-to-market. Table 2. Example of media mixing design strategy to produce 21 test conditions.

Your local Field Application Scientist will discuss with you how to test the panel based on your available resources and equipment: • For labs that may have limited time, personnel, lab space, and resources, your best option is to test the panel as is. • For those with additional time and space available, moderately complex media mixing with more test conditions, as shown in Table 2, is ideal. Upon completion of your experiment, your FAS and our internal R&D team will review the results and determine the best path forward. In this consultation, we will cover the following: • Review growth,...

Improved titers Customizing your media for your specific cell line using our chemically defined (CD) CHO test panel media provides higher titers compared to catalog media on the market. Gibco™ CHO-S™ and DG44 cell lines, when tested using the CD CHO test panel media, were shown to have higher titers than in the control medium (catalog product) (Figure 1).

Upon further development, tests were performed with chemically defined CHO panel medium 4 (GBS 4) on 2 cell lines that were responsive to LONG™ R3 insulin-like growth factor-1 (IGF-1) supplementation (Repligen). We observed a 30% increase in titer in both cell lines compared to that in catalog media conditions, when IGF-1 was used (Figure 2).

When CHO-S cells grown in CHO panel media were fed with 2X Gibco™ EfficientFeed™ C+ Supplement (2% daily, day 3–12), higher titers were observed compared to cells grown in catalog media under the same feeding conditions (Figure 3).

When chemically defined CHO panel medium 4 (GBS 4) was supplemented with LONG R3 IGF-1 in addition to feeding with EfficientFeed C+ Supplement, DG44 cells were positively affected (Figure 4).

Supplementation of fed-batch culture of DG44 cells with LONG R3 IGF-1 increases productivity. Not all cell lines will be responsive to addition of growth factor.
