BioLegend Ultra-LEAF Products
Biofunctional antibodies can either mimic or interrupt the natural biologic effects associated with ligand-receptor interactions, or have a physiological effect on a target cell or molecule. They may be used in several functional assays, including depletion, activation, neutralization, or blocking experiments. BioLegend offers antibodies in multiple formats for in vivo and in vitro assays. We are also committed to provide the highest quality and standards. That is why we are transitioning our LEAF™ (Low Endotoxin, Azide-Free) purified antibodies to Ultra-LEAF™ formulation. Contact our sales team for quotes on custom and bulk orders.

While ELISAs and flow cytometry are useful tools for scientific analysis, in vivo and in vitro functional assays can provide a unique set of answers. For these types of experiments, BioLegend has been providing 0.2 micron sterile-filtered, Low Endotoxin, Azide-Free (LEAF™) and Ultra-Low Endotoxin, Azide-Free (Ultra-LEAF™) antibody formulations, which eliminate unwanted effects from endotoxin and sodium azide. The major difference between these two formulations was the guaranteed endotoxin content. As we continue to increase our rigorous standards, LEAF™ products will be gradually replaced by Ultra-LEAF™ equivalents. Please contact our technical service group if you have any questions.
