HNE substrate inhibition. Detection of SLPI inhibition of HNE activity was performed with (A) free SLPI compared with SLPI:FWF, SLPI:UFWF, and SLPI:Fe2O3 protein corona complexes and (B) nasal lavage protein (NL, which contains endogenous SLPI) compared with NL:FWF, NL:UFWF, and NL:Fe2O3 protein corona complexes.
