Figure Lengend Snippet: In vitro characterization of new anti-CEA antibodies. (a) SPR sensorgram of G9, F7, and F4 in a scFv format. K D values were calculated to be 640 nM, 50 nM, and 7.7 nM, respectively. (b) Flow cytometry analysis with the new antibodies in IgG format on CEA-expressing CT26 cells and on CEA-negative CT26 wild-type cells. (c) Immunofluorescence staining with IgG formats on the human colon adenocarcinoma xenograft LS174T. Anti-CEA antibodies were detected in green. Blood vessels were detected by CD31 staining (red). 20× magnification, scale bars = 100 μm.

Article Snippet: Immunofluorescence analysis was performed on LS174T and HT-29 xenografts harvested from mice, on patient-derived colon cancer samples, and on a human tissue microarray (Amsbio, T6235700–5).

Figure Lengend Snippet: Ex vivo immunofluorescence-based biodistribution analysis. Immunofluorescence analysis assessed tumor targeting of new anti-CEA antibodies in IgG format. Two hundred micrograms of IgG-FITC were injected intravenously into LS174T-bearing mice. Tumors were excised 24 hours after injection. IgG-FITC was detected in green; blood vessels were detected through CD31 staining (red). 20× magnification, scale bars = 100 μm.

Figure Lengend Snippet: Quantitative biodistribution with radiolabeled anti-CEA antibodies in diabody format. Quantitative biodistribution analysis of radio iodinated anti-CEA diabodies in BALB/c nude mice bearing subcutaneous LS174T colon adenocarcinomas. Organs were harvested 24 hours after intravenous injection, and radioactivity was quantified. Results are shown as the percentage of injected dose per gram (ID/g (%)). Error bars = SEM; n = 4.

doi: 10.3390/ijms25116246

Figure Lengend Snippet: Tumor-targeted siRNA delivery of QDM and immuno-QDM. Protein expression of MDA-MB-453 (EGFR negative) and LS174T (EGFR positive) cells, and the target tumor cell binding and cellular uptake assay of Chol-siRNA, QDM, and immuno-QDM ( A – C ) were evaluated. All particles were incubated with the target cells (LS174T) for 1 h and 8 h at 37 °C and analyzed with a confocal microscope for evaluate siRNA delivery and endosomal escape analysis of QDM and immuno-QDM ( D ) (X400).
