Peroxisomes stained with anti-PMP70 rabbit polyclonal Ab and FluoTag®-X2 anti-Rabbit IgG conjugated to abberior STAR 460L (cyan; Cat. No. N2402-Ab460L-S). Golgi apparatus stained with anti-Giantin rabbit polyclonal Ab and FluoTag®-X2 anti-Rabbit IgG conjugated to abberior STAR GREEN (green; Cat. No. N2402-AbGREEN-S). Nuclear pore complexes stained with anti-NUP98 rabbit monoclonal Ab and FluoTag®-X2 anti-Rabbit IgG conjugated to abberior STAR ORANGE (magenta; Cat. No. N2402-AbORANGE-S ). Mitochondria stained with anti-TOM20 rabbit polyclonal Ab and FluoTag®-X2 anti-Rabbit IgG conjugated to abberior STAR RED (orange; Cat. No. N2402-AbRED-S).

FluoTag®-X2 anti-Rabbit IgG is a fluorescent single-domain antibody (sdAb, nanobody, VHH) with high specificity and affinity for Rabbit IgG. It binds the constant Fc domain of any Rabbit IgG, regardless of clonality or VH domain, making it an ideal secondary tool for demanding imaging applications. As part of our Smart Secondaries® range, the FluoTag®-X2 anti-Rabbit IgG is particularly suited for One-step immunofluorescence (IF) and species-independent Multiplexing.

FluoTag®-X2 anti-Rabbit IgG is site-specifically conjugated to two fluorophores per sdAb (FluoTag®–X2 variant). We also offer FluoTag®-X4 anti-Rabbit IgG, a blend of two different sdAbs, each carrying two fluorophores, that bind simultaneously to Rabbit IgG for even brighter signal. To learn more about FluoTags®, please visit our Technology section here.

We provide this product conjugated to various fluorophores and offer custom conjugation services with most commercially available fluorophores, provided these are available in a thiol-reactive activated form.
