Removal of Endotoxin from Protein in Pharmaceutical Processes

Bacterial endotoxin is the lipopolysaccharide component of the cell wall of Gram-negative bacteria, together with other cellular material that combines to form an endotoxin complex. Endotoxin is pyrogenic and it presents a risk to patients who are administered intravenous and intramuscular preparations.1Thus bacterial endotoxins pose a risk to many pharmaceutical processes and, where not controlled, to the finished products. There are different methods for endotoxin removal. These include depyrogenation,2 such as dry-heat processes applied to glassware, and rinsing,3 as might be applied to closures. These areas receive reasonable coverage within the pharmaceutical sector. Areas that are actively discussed within biotechnology fields but which receive less attention in the wider pharmaceutical context are steps to remove endotoxin bound to protein. This article considers some of the biotechnological applications for endotoxin removal.
