PHAD?-504
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.
