Cath-D expression was monitored by IHC using monoclonal anti-human cath-D (C-5; sc-377127) antibody in TMA. Staining is usually prominent in breast malignancy cells and is also detected in the tumor stroma. Scale bar, 100 m.

(A) Enrichment of anti-cath-D polyclonal scFv fragments by phage display. ScFv phages specific for human mature 34+14-kDa cath-D were selected and enriched in four biopanning rounds, and analyzed by ELISA using a HRP-labeled anti-M13 antibody. BSA, unfavorable antigen. (B) Selection of anti-cath-D monoclonal scFv fragments by ELISA. ELISA performed using bacterial culture supernatants of the best scFv clones (5 out of 400 screened clones) and recombinant human mature 34+14-kDa cath-D and 52-kDa pro-cath-D. Binding of the scFv clones to cath-D was detected with a HRP-labeled anti-Myc antibody. BSA, unfavorable antigen; IR, irrelevant scFv from the screen. (C) Purification of the anti-human cath-D scFv fragments. His-tagged anti-cath-D scFv fragments were purified using TALON resin, resolved by 12% SDS-PAGE and stained with Coomassie blue. (D) Binding of purified anti-cath-D monoclonal scFv antibodies to human cath-D from MDA-MB-231 cells. Binding of purified anti-cath-D scFv antibodies to secreted pro-cath-D and cellular cath-D from MDA-MB-231 cells was assayed by ELISA using an anti-His HRP-conjugated antibody (left panel). BSA, unfavorable antigen; IR, irrelevant scFv; = 3 Right panel, a whole cell lysate (10 g) and conditioned medium (80 l) from MDA-MB-231 cells were analyzed by 12% SDS-PAGE and immunoblotting using a polyclonal anti-mouse cath-D (sc-6486) antibody that cross-reacts with human cath-D (52-, 48- and 34-kDa isoforms). = 3. Best panel, entire mouse embryonic fibroblast lysate (25 g) was examined by 12% SDS-PAGE and immunoblotting utilizing a polyclonal anti-mouse cath-D (sc-6486) antibody against the mouse mobile cath-D 48- and 34-kDa isoforms. = 9 per group. order Istradefylline (PPTX 64 kb) 40425_2019_498_MOESM8_ESM.pptx (64K) GUID:?A0120614-6219-44AE-957B-B7A138EDE785 Additional file 9: Figure S8.
