The microtubule lableing kit can be used for immunocytochemical labeling of tubulin. The kit includes monoclonal antibodies to α- and βI-tubulin, and a rabbit polyclonal antibody to βIII-tubulin. The kit also includes goat-anti-rabbit conjugated to DyLight® 594 and goat anti-mouse conjugated to DyLight® 488 for dual labeling experiments.
