Can anyone suggest model antigen-antibody pairs (best studied models for direct and sandwich immunoassay)?

We have developed a fiber optic sensor and we wish to evaluate them for biosensing. Is there any standard antigen-antibody pair for immunoassay, namely direct and sandwich formats. For example...
