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
Antibodies by Fluorescent Protein Family
Host species, clonality, validated applications and reactivity specifications can all be found on the product pages. Click any card to view the full datasheet, msds and representative images.
