DMEM, High Glucose, GlutaPlus, No Leucine

Dulbecco's Modified Eagle Medium (DMEM), is a modified medium based on MEM, is a widely used basal medium for supporting the growth of many different mammalian cells. Cells successfully cultured in DMEM include primary fibroblasts, neurons, glial cells, HUVECs, and smooth muscle cells, as well as cell lines such as HeLa, 293, Cos-7, and PC-12.

The mammalian target of rapamycin (mTOR) complex 1 (mTORC1) plays an important role in cell growth and metabolism. In recent years, Leucine (Leu) activation of mTORC1 has become more of a research hotspot (Appuhamy et al., 2012; Averous et al., 2016; Dai et al., 2015; Gu et al., 2022; Kim et al., 2017; Son et al., 2019; Takayama et al., 2018). Therefore there is a need for leucine-deficient cell culture medium for basic research at the cellular levels.
