Article Title: Phenotypic discovery and therapeutic evaluation of an ITGA3B1 -targeting antibody-drug conjugate for bladder cancer
doi: 10.1126/sciadv.ady0041
Figure Lengend Snippet: ( A ) ELISA assessing the binding specificity of 2E7 scFv-Fc binding to the ITGA3B1 heterodimer and its individual subunits ( ITGA3 and ITGB1 ), as well as to the structurally related integrin complex ITGA6B4 and its subunits ( ITGA6 and ITGB4 ). HuIgG and BSA were included as negative controls. Data represent the mean ± SD from three technical replicates. A 450 , absorbance at 450 nm. ( B ) Dose-dependent binding of 2E7 scFv-Fc to immobilized ITGA3 , ITGB1 , and ITGA3B1 , as determined by ELISA. ( C ) Flow cytometry analysis of HEK293 cells transiently transfected with ITGA3 , ITGB1 , or both. ( D ) Flow cytometry of MDA-MB-231 cells following siRNA knockdown of ITGA3 , ITGB1 , or both ITGA3 and ITGB1 . ( E ) SPR sensorgrams showing 2E7 scFv-Fc binding to recombinant ITGA3B1 in the presence of either divalent cations or EDTA. Data shown are representative of three independent experiments.

Article Title: Phenotypic discovery and therapeutic evaluation of an ITGA3B1 -targeting antibody-drug conjugate for bladder cancer
doi: 10.1126/sciadv.ady0041
Figure Lengend Snippet: Cytotoxicity of the 2E7 ADC in human bladder cancer cell lines (UM-UC-3, CoCaB1, SCaBER, SW780, UM-UC-9, and HT-1376) following a 72-hour treatment. IC 50 values and percent inhibition were determined using cell viability assays. Treatments included the 2E7 ADC, unconjugated 2E7 Ab, and a nontargeting IgG-MMAE control ADC.
