    Bethyl anti mad2 rabbit antibody
    A. Stable inducible RPE-1 GFP-hSpindly cells were treated or not with doxycycline (DOXY). Cell extracts were prepared and immunoblotted with the indicated antibodies. In Wb hSpindly, GFP-hSpindly is the upper band and hSpindly endogenous is the lower band. B. Representative images of hSpindly levels at kinetochores of RPE-1 GFP-hSpindly treated or not with DOXY in the presence of 3.3µM nocodazole (NZ). Endogenous or exogenous hSpindly were visualized by hSpindly antibody or GFP, respectively. Bub1 or CENP-C antibodies were used as kinetochore markers, and DAPI to visualize the DNA. Scale bar: 10μm; insets, 2x zoom. C. Violin plots representing intensity or total area of hSpindly ENDO , hSpindly EXO and Bub1 at kinetochores from the experiment shown in panel B. Lines indicate mean or standard deviation. Statistical analysis was performed with a non-parametric t-test comparing two unpaired groups (***, p<0.001). D. RPE-1 GFP-hSpindly cell extracts after NZ and DOXY treatment for 24 hours were immunoprecipitated with anti-hSpindly (I) or normal mouse serum (PI) as control. Immunoprecipitated materials were analyzed by western blot using the antibodies indicated. E. Stable inducible RPE-1 GFP-hSpindly cells were treated with DOXY and NZ for 24 hours. Before collecting, mitotic cells were incubated with 0.5μM hesperadin or 1μM reversine in the presence of 20μM proteasome inhibitor MG132 for 90 minutes. Cell extracts were used to immunoprecipitate as in D. F, G RPE-1 GFP-hSpindly cell extracts treated with NZ and DOXY for 24 hours were immunoprecipitated using anti-Mad1 or <t>anti-Mad2</t> antibodies (I), with normal mouse serum used as a control (PI).

    A The blot of siRNA BAG2 and MDK, C the blot of siRNA MAD2L1. β-Tubulin was used as a loading control and GAPDH was the positive control of the siRNA transfection. As shown in the blots and also in graphs ( B ) and ( D ) there was a significant reduction of the protein level in the silenced cells, as compared to the negative CTRL. E Graph showing the comparison of protein expression in MeT-5A and MSTO cell lines of BAG2, MAD2L1, and MDK (Mann–Whitney test; p value < 0.05 were considered significant, p value = 0.0332(*), 0.0021(**), 0.0002(***), <0.0001(****)).

    A – D Representative BAG2 immunostainings in RMP, EMM, BMM, and SMM, respectively. Moderate to strong expression in the three types of MPM, while no expression is visible in the hyperplastic mesothelium in RMP (red arrow). E – H Representative MAD2L1 immunostainings in RMP, EMM, BMM, and SMM, respectively. Strong expression is present in the three types of MPM, but there are areas of discernable expression in the mesothelial cells on the pleural surface in RMP as well (blue arrow positive mesothelial area, red arrow negative area). I – L Representative MDK immunostainings in RMP, EMM, BMM, and SMM, respectively. Strong expression is seen in the three types of MPM; however, some focal expression is also detectable in the mesothelial cells on the pleural surface in RMP (blue arrow focal staining, red arrow negative staining). Magnification: RMPs ×400, MPMs ×200.
