Antibody Production Services

At Bio X Cell, we know that growing hybridoma cells and purifying antibodies in large quantities with low endotoxin levels can be technically challenging and time-consuming.

Enlist our experienced team to do this for you! Bio X Cell’s optimized fermentation process produces more antibody in less time than traditional methods. A technical project manager will guide you through the process, providing recommendations and updates along the way.
