(A) Dose- response curves of cumulus cell and granulosa cell extracts in the BMP15 ELISA are non-parallel with human pro-BMP15. (B) Similar in the GDF9 ELISA, human GDF9 is non-parallel with cumulus cell and granulosa cell. (C,D) Extraction of proteins and DNA from cumulus cells was optimised using a range of sodium chloride concentrations. Data are presented as means of duplicate measures (black dots). The horizontal dotted line refers to the level of detection.

Figure Lengend Snippet: Fig. 2. BMP15 and GDF9 structure and Western blot analysis of cumulus and granulosa cell extracts. Sequences of human pro-BMP15 (Panel A) and pro-GDF9 (Panel D). The pro- (roman text) and mature- (bold text) domains of human BMP15 and human GDF9 are shown. The residues are numbered according to the first residue of the signal peptide. Known and putative cleavage sites are depicted above the sequence. N- and O-linked glycosylation sites are also indicated (shaded in pink). The peptide sequences used to raise the BMP15 mAb#28A (A) and the two GDF9 mAbs#72B and #53/1 (D) are presented, as well as the mapped binding epitope of mAB#53/1 (D). Panel B: Western blots using biotinylated mAb#28A for detection of human pro- BMP15 and granulosa cell (GC) extracts. Each membrane was probed without or with immuno-neutralised mAb#28A using a spe cific neutralising peptide. Panels C,F: Quan tification of WB grey scale intensity and molecular weight calibrated to standard curves, without (solid lines) and with (dotted lines) antibody peptide neutralisation. Numbers on peaks correspond to the calcu lated molecular weights of bands. Panel E: Western blots using biotinylated mAb#72B for detection of human GDF9, pro-GDF9 and GC extracts. Each membrane was probed without or with immuno-neutralised mAb#72B using a specific neutralising pep tide. Red stars depict the bands which were fully neutralised in the GC extract samples.
