Why Is Sterility Important in PBS Formulation?

Phosphate-buffered saline (PB) is a common solution in life sciences research, clinical biochemistry, and cellular processes. Difficulties may arise when unsterile PBS is employed as a washing buffer, diluting certain chemicals, or as a storage medium. So why is it that important? What are the risks of using unsterile PBS in cell cultures? Let us discuss the importance of using sterile PBS in biology.

What Happens When PBS Formulation Isn’t Sterile?

PBS is a common reagent in cell culture, molecular biology, and diagnostic assays. If unsterile PBS is used, it will cause contamination, giving inaccurate results. This remains the same for failed experiments. Bacteria, fungi, or other organisms may change the pH and chemical composition of the PBS formula, thereby influencing cell viability or biological sample stability. This may have heavy consequences, particularly in vaccine development, production, pharmaceutical research, and clinical evaluation.

How Does Sterility Affect PBS in Biology?

Sterility in biological applications ensures that PBS does not introduce contaminants into a controlled environment. Contamination in the PBS formulation can harm living cells, such as undesired microbial growth, cell death, or even the death of cultures. In molecular biology, non-sterile PBS can inhibit the function of enzymes, thus hampering the generation of reliable results in very important and sensitive assays such as PCR or Western blotting. Researchers and laboratories invariably rely on high-quality sterile PBS to preserve the integrity of their work.

What Are the Best Practices for Maintaining PBS Sterility?

To maintain sterility, high-purity water, and sterile equipment are required for achieving sterility in aseptic techniques in preparing PBS. In addition, PBS is filtered through a 0.2-micron filter or pasteurized to eliminate potential contaminants. After preparation, store the prepared solution in sterile, sealed containers to prevent any microbial contamination, as airborne microorganisms may find access.
