Sample Results


A: Human IgG4 isotype control (5µg/lane) was resolved on SDS-PAGE gel in non-reducing (NR) and reducing (R) conditions and visualized by Coomassie blue staining.

B: Size Exclusion Chromatography (SEC) Analysis of human IgG4 isotype control.


C: Anti-human CD47-huIgG4 mAb and human IgG4 isotype control (Cat. #A1004) were tested for binding to CD47-expressing cells by flow cytometry. Cells were stained with PE-anti-human IgG secondary antibody.
