Description
Dulbecco’s Phosphate Buffered Saline (DPBS)
Background
Dulbecco’s Phosphate Buffered Saline (DPBS) is a balanced salt solution. It is particularly used to maintain viability of cells for a short time instead of promoting their growth. During interval period we maintain osmotic balance and physiological pH to protect cellular integrity. So, DPBS serves as an isotonic saline solution or buffer for washing cells and tissues like in chromatographic procedures where incubation is not necessary.
Grades of Phosphate Buffered Saline (PBS)
Regular Grade Buffer
PurMa Biologics manufactures Regular grade of buffer by using: PurMa™ Cell Culture Suited Water (Cat# P3W110101)
we finally sterilize the buffers by autoclaving the solution and and packding 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)
In our Class 100 Aseptic Facility we Buffer will finally sterilize the buffer by 0.2 µm filter and pack under N2
RNase and DNase Free Grade Buffer
PurMa Biologics manufactures this grade of buffer by using :PurMa™ Cell Culture Suited Water (Cat# P3W120103)
In our Class 100 Aseptic Facility we Buffer will finally sterilize the buffer by 0.2 µm filter and pack under N2
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)
In our Class 100 Aseptic Facility we Buffer will finally sterilize the buffer by 0.1 µm filter and pack under N2
The Endotoxin Removing Procedure from Buffer
PurMa biologics has the most sophisticated endotoxin removal. For that we pass the buffer through the PurMaTM Endotoxin Elimination Column (Cat# P6H1216251). Furthermore, in our proprietary column we covalently conjugate Sepharose 6B to an endotoxin-specific absorbent. we finally eliminate the residual endotoxin by passing the unbound fraction three times through 0.1µm filters.
General Feature
- PurMa Biologics manufactures this buffer in two pH: 7.4 ± 0.01 and 7.2 ± 0.01 at 25°C.
- We rigorously sterilize it by 0.22µm membrane.
- Additionally, it is a cost-effective balanced salt solution used for a variety of biochemical applications.
- PurMa Biologics packs all our buffer under N2, as a result, the pH wont change over the time before opening the bottle.
Specific Feature
- Cell Culture Suited
- We deplete Mg2+ and Ca2+ ions
- Our manufacturing process removes RNAse /DNase
- Free of Proteases.
- PurMa Biologics rigorously test for contaminating, nonspecific endonuclease, exonuclease, as well as RNase activity.
