Hybridoma Cell Medium

Hybridoma Cell Medium

Hybridoma Cell Medium, particularly formulations enriched with hypoxanthine and thymidine (HT), plays a pivotal role in the cultivation and maintenance of hybridoma cells post-HAT (hypoxanthine-aminopterin-thymidine) selection. These specialized media are meticulously designed to support the recovery and proliferation of hybridoma cells by providing essential nutrients and components that facilitate DNA synthesis through the salvage pathway. This is crucial after aminopterin in the HAT medium has inhibited the de novo nucleotide synthesis pathway, ensuring only hybrid cells with functional salvage pathways survive and thrive.

The Hybridoma Growth Medium with HT exemplifies such a specialized formulation. It is a chemically defined, animal component-free liquid medium containing hypoxanthine, thymidine, L-glutamine, gentamicin, and phenol red. This composition not only supports the high-yield growth of hybridoma cells but also ensures consistency and reproducibility in monoclonal antibody production. The absence of animal-derived components reduces the risk of contamination and variability, making it suitable for both research and therapeutic applications.

For optimal use, the medium should be thawed at room temperature or overnight at 2–8°C, avoiding thawing at 37°C to maintain its integrity. If not used immediately, it can be stored at 2–8°C for up to two weeks or aliquoted and stored at -20°C until the expiration date. This medium has been validated for the development of mouse and rat hybridomas and is instrumental in supporting hybridoma growth and expansion following HAT selection, thereby facilitating efficient monoclonal antibody production.
