Basal Medium Eagle (BME) in Earle’s Buffer
Basal Medium Eagle (BME) in Earl’s Buffer developed by Harry Eagle, and certainly is one of the most widely used of all synthetic cell culture media. BME has demonstrated widely applicable for supporting monolayer cell growth in wide variety of normal as well as transformed cell lines.
Description
Background
Basal Medium Eagle (BME) in Earle’s Buffer originally developed by Harry Eagle. This media is one of the most widely used of all synthetic cell culture media. Furthermore, Basal Medium Eagle (BME) in Earle’s Buffer, when properly supplemented, has demonstrated wide applicability, for supporting monolayer growth of a wide variety of normal and transformed cell lines. Moreover, PurMa Biologics manufacturers BME with Earle’s as well as in Hanks’ salts for use without CO2.
Ingredients
PurMa™ Basal Medium Eagle (BME) in Earle’s Buffer contains:
Earl’s buffer includes:
- Calcium chloride
- Magnesium sulfate
- Potassium chloride
- Sodium bicarbonate
- Sodium chloride
- and lastly, Sodium Phosphate, monobasic
PurMa Biologics so far, manufactures 109 types of BME in Earle’s buffer.
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. Undoubtedly, considering the highest quality, our prices certainly are extremely reasonable.
Application
Basal Medium Eagle (BME) in Earle’s Buffer provides an excellent nutritional capacity for suspension and adherent mammalian cells, including HeLa, BHK-21, 293, HEP-2, HT-1080, MCF-7, fibroblasts as well as primary rat astrocytes.

What our customers say about PurMa Biologics
Feedback from labs we supply, across our full catalogue.
Very fast, efficient, and economic service. Great for new PIs like me.
it is reliable vendor!
We always buy our agarose from PurMa and have never been disappointed.
I recently had the pleasure of interacting with Dr. Seif Azadi from Purma Biologics, and I cannot thank him enough for his expertise and prompt assistance. His deep knowledge and dedication were instrumental in meeting our laboratory’s needs with remarkable efficiency. We ordered FBS, DMEM, and Trypsin from Purma Biologics, and I’m thrilled to report that all the products have performed exceptionally well. They consistently deliver reproducible results, significantly enhancing the reliability of our experiments. Thank you, Team Purma Biologics, for your good products and support!
It’s been a pleasure working with PURMA Biologics. Their service is efficient, delivery is fast, and the quality of their products has met our expectations consistently. Very smooth collaboration overall.
PurMa products are of excellent quality and highly reliable.
Frequently asked questions
How should I store Basal Medium Eagle (BME) in Earle’s Buffer?
Store at 2 to 8 degrees C, protected from light, and do not freeze unless the label states otherwise. Freezing can precipitate salts and degrade light sensitive components such as riboflavin and folic acid. Always follow the storage line on the Certificate of Analysis for the specific lot.
What is the shelf life once opened?
Unopened and correctly stored, the typical shelf life is 12 months from manufacture. Once opened, use within about four weeks and always handle in a laminar flow hood, since the practical limit after opening is contamination risk rather than chemical stability.
Is it sterility and endotoxin tested?
Yes. Every lot is sterile filtered and tested for sterility and endotoxin, and a Certificate of Analysis is issued for each lot. The COA is available on request for any catalogue number.
Do I need to add L-glutamine?
It depends on the formulation you order. Standard formulations may contain free L-glutamine, which degrades in solution over time, while MAX formulations use a stable L-alanyl-L-glutamine dipeptide that does not require fresh supplementation. Check the option you have selected before adding more.
Can I order this in bulk or as a custom formulation?
Yes. Bulk volumes and custom formulations are made to order, including adjusted glucose, bicarbonate, buffering and cation content. Use the request bulk pricing button on this page and include the specification you need.
