Legal

Most products require no additional agreements. Cell lines and certain biological materials require a Material Transfer Agreement (MTA) on first purchase from each supplier. We handle this digitally - both parties sign online before shipment. Subsequent orders from the same supplier proceed immediately.

Support

KCell provides direct post-sales support including troubleshooting, process optimisation, and protocol guidance. Batch-specific documents available on request.

KCell Leibovitz’s L-15 Medium is formulated for the cultivation of cells in non-CO₂ environments. It replaces sodium bicarbonate with phosphate buffering and uses free-base amino acids to maintain physiological pH, allowing cultures to thrive in sealed or open-air conditions. L-15 supports a wide range of mammalian cell types, including fibroblasts, epithelial cells, and tissue explants, and is particularly suited to field or transport applications where CO₂ control is limited.

Produced under ISO and cGMP standards, KCell Leibovitz’s L-15 offers reliable composition and batch reproducibility. It is supplied in liquid or powder form, with optional inclusion of L-glutamine, phenol red, and sodium pyruvate to accommodate different experimental setups. Each batch is validated for sterility, pH stability, and osmolarity before distribution.

The medium’s self-buffering chemistry provides stable pH and nutrient conditions across extended culture periods, making it ideal for cultivated-meat, tissue-engineering, and general mammalian cell-culture workflows performed outside conventional incubator environments.
