A Western blot appearance of wild-type and mutant prostasin in kidney tissue as well as a recombinant truncated murine prostasin (amino acids 30-289, predicted mass 28 kDa) with or without deglycosylation by PNGaseF. Note that deglycosylation leads to single clear bands, compatible with glycosylation of prostasin in vivo.
B Expression of prostasin as analyzed by Western blot from kidney lysates treated with PNGaseF for deglycosylation. Representative lanes with n=3 for each genotype.
C Densitometric analysis of the obtained bands from two Western blots with n=5-6 for each genotype.
D Urinary excretion of prostasin measured with an ELISA in 24 h urine samples.
