Which of the following immunoglobulin can be suitable for diagnostic imaging or blocking molecular interactions? Correct Answer IgG4

The human IgG4 is not active in the CDC (Complement Dependent Cytotoxicity) or ADCC (Antibody-Dependent Cellular Cytotoxicity), and therefore it can be suitable for diagnostic imaging or blocking molecular interactions. IgG3, IgG2, and IgG1 are not suitable for diagnostic imaging or blocking molecular interactions.
