Why Choose St John's Fluorescent Protein Antibodies?

Well validated, well cited

Our fluorescent protein antibody range has validation across multiple applications. Check the citations tab on the product page for real peer use.

Broad Cross-Reactivity

Many products recognise multiple related fluorescent proteins — our anti-RFP antibodies detect DsRed, mCherry, mOrange, mPlum, mRFP, mStrawberry and tdTomato in a single reagent.

Secondary-Free Options

DyLight 405, 488, 550 and 633 conjugates available for TdTomato and RFP, which eliminates secondary antibody steps and simplifying multi-channel experiments.

Both Goat & Rabbit Hosts

Goat polyclonals for maximum cross-reactivity across fluorescent protein variants. Rabbit polyclonal and monoclonal options for applications requiring higher specificity or IP/ChIP compatibility.

Spectral coverage from blue through near-infrared
