Clone 28A used to detect prodomain mutations in human MBP15 biosynthesis by Western Blot

Samples were detected under reduced conditions using a human-specific BMP15 mAb (A) or an anti-FLAG M2 antibody (B). C, Five nonconserved residues (boldface type, underlined) within the α1-helix of the hBMP15 prodomain (Leu44, Glu46, Glu47, Leu49, and Glu50) were substituted with the corresponding mBMP15 residues (Ser43, Leu45, Asp46, Ala48, and Lys49) using site-directed mutagenesis. (Al-Musawi, S et al.)

Clone 28A used to purifiy and quantify human BMP15 by Western Blot

B. The processed mature region of pro-mature BMP15 was quantified by Western blotting [mab28 monoclonal antibody [42]] using the mature region of hBMP15 (R&D Systems) as a standard. Lanes 1–4: mature region of BMP15 (R&D Systems); 200, 100, 50 and 10 ng, respectively. Lanes 5–7: decreasing doses of the purified BMP15 pro-mature complex. (Sudiman, J et al.)

Clone 28A used to detect BMP15 in HEK-293T cell lines by Immunoblotting

Image caption: (B) Recombinant proteins produced from stable HEK-293T cell lines and subjected to SDS–PAGE immunoblotting (ECL). 1: BMP15wt, 2: BMP15 form 1, 3: BMP15 form 2 (with C-terminal Flag tag), 4: GDF9 wt (recognised by the GDF9 specific mAb-53 (Gilchrist et al., 2004b)), 5: TGF-β 200 ng. All samples were reduced with 10 mM DTT before running into the gels. The specific BMP15 mAb-28 reveals the 16–17 kDa mature human BMP15 protein. The mAb-28 does not cross-react with GDF9, showing the specificity of the antibody to BMP15. (Pulkki M,M et al.)
Dilution used: 1:10000
