Minimum Essential Media (MEM) In Hanks’ Buffer
Minimum Essential Media (MEM) In Hanks’ Buffer is a modification of Basal Medium Eagle. This media includes higher concentrations of amino acids making it suitable for cultured mammalian cells. Moreover, PurMa Biologics manufactures two types of media, MEM in hanks buffer as well as MEM with Earle’s buffer for use in a CO2 incubator, or with Hanks’ salts for use without CO2.
- ✓Proudly made in the USA, manufactured in house
- ✓Certificate of Analysis available for every lot
- ✓Backed by decades of cell culture and protein biochemistry expertise
- ✓Bulk pricing, purchase orders, and custom formulations welcome
Description
Background
Minimum Essential Media (MEM) In Hanks’ Buffer is a modification of Basal Medium Eagle. It was originally developed by Harry Eagle for specific 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’s buffer for use in a CO2 incubator, or with Hanks’ salts for use without CO2.
PurMa™ MEM media in Hank’s buffer includes Hank’s buffer
Hanks buffer, it contains:
- Potassium Chloride
- Potassium Phosphate, monobasic
- Sodium Bicarbonate
- Sodium Chloride
- Sodium Phosphate, dibasic
Additionally, Minimum Essential Media (MEM) In Hanks’ Buffer contains:
- Low level of glucose (1.00 g/ liter)
- Sodium bicarbonate (0.35 g/L). If , however, higher than 5% CO2 is used, a higher % of sodium bicarbonate is needed.
- 2 mM L-glutamine (292 mg/L)
Moreover, PurMa Biologics manufactures 122 types of MEM including several types of essential media MEM in Hanks’
Why PurMa Biologics? Why we stand behind our cell culture media
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.
Applications
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).
