The paxillin phospho-regulation kit can be used for immunocytochemical co-localization of paxillin phosphorylation at Ser-83 compared to the total expression of paxillin. The kit includes rabbit polyclonal and mouse monoclonal antibodies along with Goat-anti-rabbit conjugated to DyLight® 594 and Goat anti-mouse conjugated to DyLight® 488 for dual labeling experiments.
