πŸ“° "The Difference Between Sterilizing Fluids and Endotoxin Removal"

You've sanitized your system. You have sterilizing grade filters installed at key points in your process. Your bioburden measurements are low, but you still have endotoxin issues. What's going on? Endotoxins or lipopolysaccharides (LPS) are released into the environment during active growth, mechanical damage, lysis, and death of gram-negative bacteria cells. Therefore, endotoxins will be likely present in your process stream coming from the original water source. Sterilization processes can release endotoxins in case when gram-negative bacteria are destroyed.
Considering the intrinsic pyrogenicity, endotoxin concentrations need to be reduced to the lowest level possible. Endotoxins are heat stable and persist even after bacterial death. These cell fragments are typically smaller than 0.01 micron, and will not be removed by a 0.22 or even a 0.10-micron sterilizing filter.

πŸ“° "Bioburden Failures in Sterilizing Filtration"

Sterile filtration is employed at various stages of biopharmaceutical manufacturing, such as solution clarification, bioburden reduction, particulate removal, and mycoplasma reduction, prior to drug-product filling. It is particularly well-suited for products that are sensitive to heat or radiation.

πŸ“° "Filter Integrity Testing Without Capital Expenditure"

For many filter users, it's crucial, if not essential, to have a method for testing your filters to ensure their proper functioning. This test can be conducted before filtration to verify that the process will operate as intended, or after filtration to check for any issues that may have arisen during processing. In some critical applications, it may be beneficial to perform both types of tests. The most prevalent method involves conducting a filter integrity test.
