Serox BHK is a serum-free cell culture medium, formulated without any animal-derived component and optimized for the culture of suspension BHK21 cells at high-density and viability and efficient propagation of viruses. Serox BHK has been shown to be an optimal formulation for the growth and maintenance of BHK21 suspension cell lines used for viral vaccine production, and qualified for instance for the production of Foot and Mouth Disease virus (FMDV).

Glasgow MEM (GMEM) was originally formulated for growing BHK 21 cells. The original formulation is an Eagle's Basal Medium modified to contain two times the normal concentration of amino acids and vitamins. It is intended for use with adherent cell lines.

The GMEM was developed as a modification of BME to culture primary baby hamster kidney(BHK) cells. This version has twice the concentration of vitamins and amino acids
