Gibco CHO Media offer high performing options in multiple formats designed to optimize your workflow. We have extended our portfolio to include our newest media formulations: Gibco Efficient-Pro™ Medium and Gibco Efficient-Pro™ Feeds 1 and 2 designed for use with a range of CHO cells. This complete collection provides a range of options for optimal CHO cell culture including High-Intensity Perfusion (HIP) CHO Medium, and Gibco ExpiCHO Stable Production Medium (SPM).
What's new—Gibco Efficient-Pro Medium & Feeds help enhance CHO cell protein quality and productivity
Gibco Efficient-Pro Medium and Gibco Efficient-Pro Feeds 1 and 2 help deliver superior product performance, improved product titer, better protein quality and lot-to-lot consistency, which provides more control and predictability. Each medium is chemically defined, completely scalable and available as Gibco Advanced Granulation Technology (AGT) formats for sustained cell viability. The AGT dry media format enables a simple and scalable reconstitution process. These formats help maximize process efficiency with simplified preparation. Customers with larger-scale operations will benefit from longer bioreactor runs, reduced risk in reconstitution and flexibility to support these CHO cell lines.

High-Intensity Perfusion CHO Medium
Gibco High-Intensity Perfusion (HIP) CHO Medium can be used at multiple concentrations to support your process from seed train to production.
Just as it can be used at multiple concentrations, it can be used in multiple perfusion processes: N-1 and seed train, intensified fed-batch, concentrated fed batch, and continuous perfusion. Numerous CHO cell lines (CHO-S, CHO-DG44, CHO-GS, CHO-K1) have been tested in these perfusion processes with HIP CHO Medium.
In addition, the medium supports high cell densities at low medium exchange rates, which improves process efficiency, as low as 1 vessel volume/day (VVD).

Find your optimal match with Gibco cell culture media
There are several pathways to find the right media or media and feed solution for CHO cell cultures. These pathways include selecting a standard or off-the-shelf media, our CHO media test panel, or a media development or optimization service. In order to find the right path, we need to remove the biggest obstacle; luck.
Often time, your goals on what you want to accomplish will narrow down the best selections for you.
Questions to consider:
- What are you hoping to accomplish?

Frequently, cell line specific component dependencies, like insulin and other growth factors, are missed when evaluating media. These are components that are needed for your cell line to thrive (growth, productivity) and if they are not present in the tested media, you may miss out on the optimal solution.
Matching media to your cell line should include an evaluation of whether these dependencies are in the media of choice or not (Tables 1 and 2) to determine whether you need to add them in or not.
Even with the cell line dependency component, in most cases, adaptation is required to see optimal results.
Additional components may also need to be considered for an optimal outcome (Table 3).
Questions:
- Do you know if your cell line has any dependencies?
- Are you planning on adapting the cells to the media?
- Are other considerations necessary for the best result?
Standard catalog media | Media test panel | Development or optimization service | |
Dependencies | Table 1 lists media containing growth factors Table 2 lists media without growth factors | Our media test panel does not contain typical cell line dependencies by default and can be added in as requested. | Our service offerings will evaluate these factors and other factors as specified. |
