Antisera were raised against synthetic peptides from the prosegment of
human prorenin. The use of each of these for detection of the appropr
iate prosegment region of prorenin was validated by development of an
ELISA protocol standardised with recombinant prorenin present in cultu
re medium conditioned by myeloma cells transfected with a prorenin exp
ression plasmid. Detection of the respective epitopes in the prosegmen
t required prior exposure of the prorenin in the medium to acid pH in
order to partially unfold the prorenin molecule by dislodging the pros
egment from the main body of the protein. By these ELISA protocols, th
e form of latent renin present in representative samples from ovarian
cyst and follicular fluids was analysed; one follicular cyst fluid was
found to contain full-length prorenin whereas the fluid from a benign
cyst and ovarian follicular fluid samples contained the precursor in
truncated form.
