protag-HiRes anti-RFP is a blend of two camelid single-domain antibody (sdAb) produced by NanoTag Biotechnologies GmbH. It is ideal to detect mRFP and mCherry.

In protag-HiRes anti-RFP-X4, two fluorophore molecules are site-specifically coupled to each individual single-domain antibody. The blend of two camelid single-domain antibodies therefore simultaneously targets up to four fluorophores to the protein of interest, which ensures extra-bright signals. Owing to the small size of our protag single-domain antibodies, the distance between the target epitope and each fluorophore is below 4 nm. In comparison to conventional detection systems using conventional antibodies, our protag-HiRes anti-RFP-X4 can thus improve the localization accuracy by 10-15 nm. Both features - superior brightness and precise fluorophore placement - render our protag-HiRes anti-RFP-X4 products excellent tools for all microscopy techniques.
