Moreover, MEM-\u03b1-N-HBSS is widely used for a variety of suspension and adherent cells. Calcium, however, plays a crucial role in media as eliminating this ion facilitates the growth of cells in suspension cultures.<\/p>\n<h2>Ingredients<\/h2>\n<p>MEM-\u03b1 with nucleosides is basically the modified version of MEM-\u03b1 and contains:<\/p>\n<ul>\n<li>Ribonucleosides<\/li>\n<li>Deoxyribonucleosides<\/li>\n<li>Non-essential amino acids.<\/li>\n<li>Sodium pyruvate.<\/li>\n<li>Lipoic acid.<\/li>\n<li>Vitamin B12.<\/li>\n<li>Biotin and,<\/li>\n<li>Ascorbic acid.<\/li>\n<\/ul>\n<h2>PurMa\u2122 MEM-\u03b1-N-HBSS contains HBSS buffer<\/h2>\n<p>The composition of HBSS buffer:<\/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<p>Additionally, MEM \u03b1-Modification with Nucleosides in Hanks\u2019 Buffer also Contains:<\/p>\n<ul>\n<li>Low level of glucose (1.00 g\/ liter)<\/li>\n<li>Sodium bicarbonate (0.35 g\/L)<\/li>\n<li>2 mM L-glutamine (292 mg\/L)<\/li>\n<\/ul>\n<p>PurMa Biologics manufactures 119 types of MEM-\u03b1-N-HBSS<\/p>\n<h2>Why PurMa Biologics? 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>Application<\/h2>\n<p>Furthermore,\u00a0 MEM-\u03b1-N-HBSS is used for various cell types such as keratinocytes, primary rat astrocytes, as well as human melanoma cells. Also, MEM-\u03b1-N-HBSS has been used for the isolation of mesenchymal stem cells, adipose-derived stem cells, and osteoblasts. Moreover, MEM \u03b1-Modification is widely used for primary osteoblast cultures.<\/p>\n<h2>Formulation<\/h2>\n<p>For complete formulation\u00a0 click here as well as &#8221; formulation Tab : <span style=\"color: #0000ff;\"><strong><a style=\"color: #0000ff;\" href=\"https:\/\/purmabiologics.com\/blog\/wp-content\/uploads\/2023\/06\/MEM-alpha-with-Nucleosides-Formulation-in-Hanks-Buffer-HBSS-P3S410124.pdf\" target=\"_blank\" rel=\"noopener\">MEM alpha with nucleoside in HBSS Buffer Formulation<\/a><\/strong><\/span><\/p>\n<h2>References<\/h2>\n<ol>\n<li><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21835026\/\" rel=\"nofollow noopener\" target=\"_blank\"><span style=\"color: #0000ff;\">A previously functional tetracycline-regulated transactivator fails to target gene expression to the bone<\/span>. <\/a>Schmidt et al.
