Activated B-Cell Discovery with Cellestive
Harness Hybridomas to Your Advantage
Activated B-cells immortalized as hybridomas have, time and again, proven their mettle in generating effective antibodies against targets of interest. In short, they have been – and remain – robust, dynamic and dependable sources for antigen-specific antibodies.

It Offers Time Tested Technology
Hybridomas have existed for decades, giving rise to more research, reagent, and therapeutic antibodies than any other technology. When used strategically, a robust hybridoma program can quickly and easily deliver monoclonal antibodies to a target.
It Captures Antigen- Activated Cells
Hybridomas immortalize activated B-cells in response to direct antigen challenge, making them highly selective for rare antigen-specific B-cells. They generate populations of cells with the highest percentage of monoclonal antibodies binding to antigen.
It’s Stable
and Robust
Hybridomas create stable cell lines that secrete functional antibodies from the start. This enables early testing without recombinant expression, saving both time and resources. They also self-select for monoclonal antibodies that are natively folded and actively secreted by mammalian cells.
Proven Success from a Proven Partner
At Antibody Solutions, we know how to get the most out of hybridomas and we've been doing it for three decades. More importantly, we know how to successfully apply its strengths to your program.
Harness Flexibility
Our exclusive Hybridoma Library™ process offers the flexibility to screen your hybridomas through multiple formats. These include conventional plating, AI-powered xPloration® from OmniAb®, or antigen FACS sorting. Choose one or more formats to suite your discovery project’s unique needs and budget.
Harness Control
Our Hybridoma Library™ process uses proprietary growth and cloning factors to ensure recovery and outgrowth of activated B-cells. Cryopreservation of libraries and clones are offer natural testing and decision points in each program. This way, you’re not locked into potentially unproductive efforts, while giving you the opportunity to revisit your cells’ potential later.
Harness Speed
Put efficiency to work using high-throughput flow cytometry sorting to screen and clone single cells without the need for multiple rounds of sub-cloning. Or use xPloration® to screen hundreds of thousands of antibody-secreting cells in a single run with sequencing. Either way, you get valuable results fast.
Harness Clarity
Our activated B-cell pathways — either FACS sorting or xPloration — ensure antibody monoclonality while cutting down risks of false positives and the need for sub-cloning. They deliver rich, functional data and, almost equally important, they do it early. This allows you to focus on the sequences that are most likely to deliver your desired results.
Joined to a Common Goal: Your Success
Hybridoma capture of activated B-cells uses natural collaboration to win. Appropriately, our team can do exactly the same for your target. Let’s discover together if our activated B-cell pathway is an ideal match for your antibody discovery program.
Capitalize on Antigen Activation
Activated B-cells sit squarely in a useful “sweet spot,” delivering a valuable mix of both relative affinity and diversity among antibody immune repertoires. Our Hybridoma Library approach is time-tested and offers the broadest number of formats for screening. It can be of substantial benefit to discovery projects of any size, regardless of time or budget limitations. Combined with our scRNA sequencing and Rapid RecAb expression, we can directly express your hits in a fit-for-purpose format.

But, targeting activated B-cells is just one of the pathways that may meet your project or target goals. That’s why Antibody Solutions’ Cellestive platform provides a cost- and time-efficient way to navigate multiple pathways, in parallel, with your primary route. For instance, if your project calls for a larger number of diverse hits across a range of affinities, adding our plasma B-cell and memory B-cell discovery pathways to your discovery program can deliver a broader set of antibodies.
Activated B-Cell Discovery Services with a Bias Toward Action
You may have questions about how to maximize an activated B-cell approach to its full potential. Or you might have already decided that the parallel discovery paths offered by the Cellestive platform are perfect for your project. Either way, we’d love to hear from you and take the next step together.
