The hybridoma secreting MAb to Polyubiquitinylated Conjugates (FK1) (Prod. No. BML-PW8805) was generated by fusion of splenocytes from Balb/c mice which had received repeated immunisation with a crude preparation of polyubiquitinylated-lysozyme. MAb to Polyubiquitinylated Conjugates (FK1) has been extensively characterised by one-dimensional Western blotting and has been shown to recognise only polyubiquitinylated proteins and not monoubiquitinylated proteins or free ubiquitin.

Technical Info/Product Notes:In order to investigate the status and extent of protein ubiquitinylation it is necessary to have available a range of antibodies capable of differentiating firstly between free ubiquitin and ubiquitin-protein conjugates and, secondly and more importantly, between those that are mono-ubiquitinylated and those that are poly-ubiquitinylated. The antibodies PW8805 (clone FK1) and PW8810 (clone FK2), originally developed in the laboratory of Professor Hideyoshi Yokosawa at Hokkaido University, Japan, are specific for ubiquitin-protein conjugates and show no reactivity with free ubiquitin. The hybridoma secreting the antibody FK1 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 FK1) has been extensively characterised by one-dimensional Western blotting (see Figure) and has been shown to recognise only polyubiquitinylated proteins and not monoubiquitinylated proteins or free ubiquitin. The immunoglobulin subclass is IgM. 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, thus by using the antibodies in concert the degree of protein ubiquitinylation may be determined.

ELISA: 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. Immunoblotting: For Western blotting an initial dilution of 1:1000 is recommended. Note: Milk should NOT be used in blocking/antibody binding solutions. 1% BSA in PBS or TBS Tween should be used instead.
