Low endotoxin, azide-free bioactive antibodies

​​Antibodies for in vitro and in vivo studies, including neutralization, blocking or activation/proliferation.

​​​​The presence of endotoxin can significantly impact both in vitro and in vivo experiments, causing non specific cellular responses and false readings in cell-based assays. 

Endotoxin is an aggregate of acidic lipopolysaccharides (LPS) that is shed from bacteria and is a heat-stable ubiquitous contaminant. Although bacteria are often removed by using a 0.2 μm sterilizing grade filter, LPS contamination is difficult to eliminate via filtering or autoclaving. Limulus amoebocyte lysate (LAL) assays are the most commonly used endotoxin detection methods.
