PHAD™-504 A89810 (Previously 699810) Monophosphoryl Lipid A-504
PHAD™-504 was designed as a synthetic structural analog of detoxified MPLA derived from E. coli lipopolysaccharide (LPS). It is structurally similar to PHAD™, differing only in the length of a single fatty acid chain. As expected, the activity of PHAD™-504 is quite similar to that of PHAD™, making the two products interchangeable as adjuvants in vaccine or immunotherapy formulations.
