General description

Modification of the original MEM formulation. Earle′s salts have been replaced with Hanks′ salts. Since the bicarbonate concentration is substantially lower, this medium has a substantially reduced buffering capacity.

Quantity

Formulated to contain 10.6 grams of powder per liter of medium.

Reconstitution

Supplement with 0.35 g/L sodium bicarbonate.

Storage Class Code

13 - Non Combustible Solids

The signaling cascade initiated in response to DNA double-strand breaks (DSBs) has been extensively investigated in interphase cells. Here, we show that mitotic cells treated with DSB-inducing agents activate a "primary" DNA damage response (DDR) comprised of early signaling events...

Through negative regulation of gene expression, microRNAs (miRNAs) can function as oncosuppressors in cancers, and can themselves show altered expression in various tumor types. Here, we have investigated medulloblastoma tumors (MBs), which arise from an early impairment of developmental processes...

MEM (Minimum Essential Medium Eagle)

A large selection of MEM formulations. Minimum Essential Medium (MEM), developed by Harry Eagle, is one of the most widely used of all synthetic cell culture media.

Protocols

Powdered Media Preparation Instructions

Powdered media and salt mixtures are extremely hygroscopic and should be protected from atmospheric moisture.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
