Monoclonal antibodies (MAb) Ras 10 and Ras 11 were raised to an activated human Harvey-ras p21 and shown to react with recombinant p21 as well as p21 derived from human and rodent cells. Characterization studies by ELISA, immunoprecipitation and Western blot procedures demonstrated that MAb Ras 10 (IgG2a) and Ras 11 (IgG2b) react with normal p21, activated p21, and p21 from each of the Harvey, Kirsten and N-ras families. Studies illustrated that MAb Ras 10 and Ras 11 can also be used in flow cytometry and immunohistochemistry to specifically detect cellular p21. ELISA, immunoprecipitation and Western blot studies comparing rat anti-p21 MAb Y13-259 with Ras 10 and Ras 11 demonstrated that Ras 10 and Ras 11 had a greater sensitivity for ras protein detection than Y13-259. Collectively, these studies illustrate that MAb Ras 10 and Ras 11 can be applied to a variety of assay formats to detect ras proteins and, therefore, may be valuable tools in detecting and measuring of ras protein expression in normal, neoplastic and pre-neoplastic cells. | 2076896
