criteria used to identify the tubulins included migration on two-dimensional gels with myxamoebal tubulins purified by self-assembly into microtubules in vitro , peptide mapping with staphylococcus v8 protease and with chymotrypsin , immunoprecipitation with a monoclonal antibody specific for beta-tubulin , and , finally , hybrid selection of specific mrna by cloned tubulin dna sequences , followed by translation in vitro .
