Earle’s Balanced Salt Solution (EBSS)
Earle’s Balanced Salt Solution (EBSS) is an isotonic buffer solution. It is however, composed of inorganic salts and carbohydrates as an energy source designed for the short-term maintenance of mammalian cells in a CO2 environment.
Description
Background
Earle’s Balanced Salt Solution (EBSS) is an isotonic buffer solution. It is however, contains inorganic salts and carbohydrates as an energy source designed for the short-term maintenance of mammalian cells in a CO2 environment. The solution additionally provides an ideal environment to preserve the structural and physiological integrity of cells invitro by maintaining pH as well as the balance between intra and extracellular osmotic pressure.
General Features
- It is cost effective.
- Cell Culture Suited
- This buffers maintains the cell integrity of cells or tissues during irrigation, transportation, or dilution.
- Provides an consistent environment during the washing and re-suspend cells
- PurMa Biologics offers EBSS in three pH formats, pH 7.2, 7.4, and pH 7.6.
Specific Features
- Glucose maintains the intra and extracellular osmotic pressure as well as provides the principal source of energy for cellular metabolism.
- EBSS Provides water and important inorganic ions necessary for cellular metabolism.
- This buffer Provides a buffer solution to maintain a medium in physiological pH (7.2-7.6)
- PurMa Biologics rigorously depletes Mg2+ and Ca 2+ from the buffers
- Free of RNAse /DNase
- Free of Proteases. It is rigorously tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity.
- It is rigorously tested for contamination of endotoxin and mycoplasma.
- Is manufactured in three pH: 7.2 ± 0.01, pH: 7.4 ± 0.01, and 7.6 ± 0.01 at 25°C.
- Sterile filtered by 0.22µm membrane (in case of endotoxin-depleted EBSS by 0.1µm)
- As it is packed under N2, the pH won’t change over time before opening the bottle.
Application
EBSS is especially has an excellent role in protocols requiring the use of consistent conditions such as crosslinking, biotinylation, and fluorescent labeling reactions which require an amine-free buffer.

PurMa Biologics Manufactures Several Grades of Buffers
Regular Grade Buffer
PurMa Biologics manufactures Regular grade of buffer by using: PurMa™ Cell Culture Suited Water (Cat# P3W110101)
We sterilize the buffers by autoclaving the solution. Finally we pack the buffer in our Class 100 Aseptic Facility.
Cell Culture Suited Grade Buffer
PurMa Biologics manufactures this grade of buffer by using :PurMa™ Cell Culture Suited Water (Cat# P3W110101)
After adjusting the pH, we finally, sterilize the buffer by 3 times passing through 0.2 µm filters. Additionally, We pack the buffer under N2 gas in our Class 100 Aseptic Facility.
RNase and DNase Free Grade Buffer
PurMa Biologics manufactures this grade of buffer by using :PurMa™ Ultra-Pure Cell Culture Suited Water (Cat# P3W110102)
We sterilize the buffers by autoclaving the solution. Additionally, we pass the buffer three times through 0.1 µm filters, and finally pack it under N2 gas in our Class 100 Aseptic Facility.
Cell Culture Suited / Endotoxin Depleted Grade Buffer
PurMa Biologics manufactures this grade of buffer by using: PurMa™ Ultra-Pure Cell Culture Suited Water (Cat# P3W110102)
After depleting the endotoxins (see below for more details), we sterilize the buffer by 3 times passing through 0.1 µm filters and pack under N2 gas in our Class 100 Aseptic Facility
The Endotoxin Removing Procedure from Buffer
PurMa Biologics has the most sophisticated endotoxin removal procedure. To remove this pathogen, we pass the buffer through the PurMa™ Endotoxin Elimination Column (Cat# P6H1216251). Furthermore, in our proprietary column, we covalently conjugate Sepharose 6B to an endotoxin-specific absorbent. We finally eliminate the endotoxin residual by passing the unbound fraction three times through 0.1µm filters.

Review: I have worked directly with PurMa biologics on a number of projects ongoing in my lab. I find the media and the specialty Lipid Depleted Serum to be high quality and very consistent among batches, which is critical to our adipogenesis projects using primary stem cells. Also, the service from PurMa is outstanding for my lab.

Review: I started my lab using the regular Gibco media components. We have shifted to Purma past 6 months and see no difference in the quality of our cell culture. Simply saying that Purma is cheaper, quicker to deliver and as good as Gibco. The best part was that Purma customized several media for our fish cell lines which was really helpful. Lastly, Seif walked through the customization of media over Zoom, that gave a lot of confidence for using those media solutions.

Review: We bought Premium FBS and DMEM cell culture media from PurMa Biologics. We are using them for several mammalian cell line and primary cell culture and the cell growth is perfectly fine. We are totally satisfied with the product quality. Importantly as local vendor, we can have the product available as per our demand ASAP.

Review: Reliable and dependable products. We purchased lipid-depleted FBS (LD-FBS) from PurMa Biologics and it worked great. We cross-checked the lipid content in the serum by GC-MS and Triglyceride assay and as advertised, did not find any lipids in the FBS.
