It was originally developed by Harry Eagle for specific\u00a0 requirements of certain subtypes. Additionally, it includes higher concentrations of amino acids which is more suitable for cultured mammalian cells. Moreover, PurMa Biologics manufactures MEM with Earle\u2019s buffer for use in a CO<sub>2<\/sub>\u00a0incubator, or with Hanks&#8217; salts for use without CO<sub>2<\/sub>.<\/p>\n<h2>PurMa<sup>\u2122<\/sup> MEM media in Hank\u2019s buffer includes Hank&#8217;s buffer<\/h2>\n<p>Hanks buffer, it contains:<\/p>\n<ol>\n<li>Potassium Chloride<\/li>\n<li>Potassium Phosphate, monobasic<\/li>\n<li>Sodium Bicarbonate<\/li>\n<li>Sodium Chloride<\/li>\n<li>Sodium Phosphate, dibasic<\/li>\n<\/ol>\n<h2>Additionally, Minimum Essential Media (MEM) In Hanks\u2019 Buffer contains:<\/h2>\n<ul>\n<li>Low level of glucose (1.00 g\/ liter)<\/li>\n<li>Sodium bicarbonate (0.35 g\/L).

Why we stand behind our cell culture media<\/h2>\n<p>Our products are the outcome of 30 years of experience in cutting edge science. We routinely manufacture over 1500 media. We have the most comprehensive collection of cell and tissue culture media. Moreover, We utilize 99% pure amino acids. This will significantly increase the consistency among your experiments. Considering the highest quality, our prices certainly are extremely reasonable.<\/p>\n<h2>Applications<\/h2>\n<p>Minimum Essential Media MEM has been used for the cultivation of a wide variety of cells grown in monolayers attached or in suspension cell lines such as HeLa, BHK-21, 293, HEP-2, HT-1080, MCF-7, and fibroblasts as well as primary rat astrocytes. MEM contains no proteins, lipids, or growth factors. Therefore, MEM requires supplementation, commonly with 10% fetal bovine serum (FBS).<\/p>\n<h2>Formulation<\/h2>\n<p>Complete formulation click here as well as in Formulation Tab: <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/purmabiologics.com\/blog\/wp-content\/uploads\/2023\/06\/MEM-HBSS-Formulation-in-Hanks-Buffer-P3S410122.pdf\" target=\"_blank\" rel=\"noopener\"><strong>MEM (HBSS) Formulation in Hanks&#8217; Buffer<\/strong><\/a><\/span><\/p>\n<h2>References<\/h2>\n<ol>\n<li><span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/3401543\/\" rel=\"nofollow noopener\" target=\"_blank\">Culture of granulosa cells in collagen gels: the influence of cell shape on steroidogenesis. <\/a><\/span>Carnegie et al.
