MEM was developed by Harry Eagle based on his early Base Eagle Medium (BEM) formulation, and many other modifications have since been made to MEM, including alpha-MEM, EMEM, GMEM and Temin’s modified media. JSBio offers a range of improved MEM that can be customized to your needs.

DMEM (Dulbecco's Modified Eagle Media) is a widely used basal medium for supporting the growth of many different mammalian cells. At present, DMEM is the preferred media for primary fibroblast, neuron cell, glial cell and smooth muscle cell, hybridoma cell, HeLa cell, COS-7 cell, HEK293 cell and other cells.

Phosphate-buffered saline (PBS) is a balanced salt solution that is used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue samples, diluting cells for counting, and preparing reagents.

Celsource® Feed B is a feed reagent for improving protein expression in mammalian cells, which is animal component free, chemically defined, protein-free, without hydrolysate. The Celsource® Feed B（100X）combine use with CHO and HEK293 Transfection Feed in the HEK293 transient transfection expression platform can further increase the protein expression after transfection.
