ReadiLink™ xtra Rapid XFD488 Antibody Labeling Kit

BSA-Compatible

XFD488 is manufactured by AAT Bioquest, and it has a chemical structure similar to that of Alexa Fluor® 488 (Alexa Fluor® is the trademark of Thermo Fisher). ReadiLink™ xtra rapid antibody labeling kits require essentially only 2 simple mixing steps without a column purification needed. Specially formulated and preactivated XFD488 (chemically equivalent to Alexa Fluor® 488) used in this ReadiLink™ kit is quite stable and shows good reactivity and selectivity with antibodies. The kit has all the essential components for labeling ~2x50 ug antibody. Each of the two vials of preactivated XFD488 dye provided in the kit is optimized for labeling ~50 µg antibody. ReadiLink™ xtra XFD488 rapid antibody labeling kit provides a convenient and robust method to label monoclonal and polyclonal antibodies with green fluorescent XFD488 fluorophore. XFD488 is one of the most used fluorophores for labeling antibodies.
