VHH is the variable domain of camelids heavy chain antibodies, and it is also called single-domain antibody (sdAb) or nanobody. Due to the large size, traditional secondary antibodies hinder tissue penetration and reduce image resolution in super-resolution fluorescence microscopy which made VHHs/SdAbs an ideal candidate to replace such reagents. Additionally, site-specifically labeled SdAbs can place fluorophores closer than 2 nm to the antigen or even tolerate up to three dyes. Combining excellent antigen specificity, minimal lot-to-lot variation, and sustainable supplement, VHHs/SdAbs is considered to be a promising tool for super-resolution imaging.
