Application
Gelatin has received significant attention in the biomedical field due to its inherent bioactivity. Low endotoxin gelatin from porcine skin, gel strength 300 bloom is a high bloom (high molecular weight) gelatin featuring less than 10 endotoxin units (EU) per gram. Endotoxins primarily consist of lipopolysaccharides from the outer membrane of gram-negative bacteria. Once in the bloodstream, endotoxins are capable of eliciting a strong immune response, potentially leading to fever, shock, a drop in blood pressure, and even potentially death. In addition to this immune response, several reports suggest endotoxins may also damage various types of cells. To avoid adverse effects, raw materials should contain the lowest level of endotoxins possible when used in biomedical or regenerative medicine research applications. This low endotoxin gelatin is derived from alkaline-treated porcine skin and has a variety of potential applications in the fields of regenerative medicine, medical devices, and tissue engineering research.

In an effort to decrease deaths from gram-negative bacteremia and endotoxin shock, we treated bacteremic patients with human antiserum to endotoxin (lipopolysaccharide) core. Antiserum was prepared by vaccinating healthy men with heat-killed Escherichia coli J5; this mutant lacks lipopolysaccharide oligosaccharide

Trace amounts of endotoxin (lipopolysaccharide: LPS) are assumed to contaminate commercially available fetal bovine serum (FBS) for tissue or cell culture during the manufacturing process. We examined how cultured cells were affected by the endotoxin and how much endotoxin was
