Technical Info/Product Notes:The antibodies BML-PW8805 (clone FK1) and BML-PW8810 (clone FK2) are specific for ubiquitin-protein conjugates and show no reactivity with free ubiquitin. Clone FK1 recognises only polyubiquitinylated proteins and not monoubiquitinylated proteins or free ubiquitin, whilst clone FK2 recognises both mono- and poly-ubiquitinylated species but not free ubiquitin.

These antibodies have been used to not only investigate the dynamics of ubiquitin conjugation but also for the development of immunoassays permitting quantification of serum and intracellular multiubiquitin chains. Over recent years these antibodies have found very wide application in many areas of investigation and there is an associated supporting bibliography.

The hybridoma secreting the antibody FK2 was generated by fusion of splenocytes from Balb/c mice which had received repeated immunisation with a crude preparation of polyubiquitinylated-lysozyme. The antibody (clone FK2) has been extensively characterized by one-dimensional Western blotting and has been shown to recognise polyubiquitinylated (all linkage types) and monoubiquitinylated proteins but not free ubiquitin.

FK2 antibody BML-PW8810 was conjugated to fluorescein by a proprietary method. The fluorescein-labelled FK2 monoclonal antibody (BML-PW1210) facilitates ready detection of mono- and poly-ubiquitinylated protein conjugates in cells by fluorescence microscopy.
