A fluorescent derivative of ribosomal protein S18 which permits direct observation of messenger RNA binding.
70 S Escherichia coli ribosomes were reacted with the fluorescent dye N-(iodoacetylaminoethyl)-5-naphthylamine-1-sulfonic acid for 10 min under mild conditions. The resulting ribosomes were fully active. 30 S subunits isolated from these particles were also fully active. They contain approximately 0.7 eq of fluorescent dye. Nearly all of it is attached to protein S18. Competitive reaction with ...
متن کاملEffects of a podophyllotoxin derivative on tissue culture systems in which human cancer invades normal tissue.
In the search for clinically effective antitumor agents, numerous biologic systems have been con sidered as possible screening devices (4). Some in vestigators have preferred test systems with hu man tumors, with the thought that these may pro vide the greatest possibility of correlation with clinical cancer. Experiments have been conducted with chemical agents and human cancer in several ways,...
متن کاملFractional Derivative as Fractional Power of Derivative
Definitions of fractional derivatives as fractional powers of derivative operators are suggested. The Taylor series and Fourier series are used to define fractional power of self-adjoint derivative operator. The Fourier integrals and Weyl quantization procedure are applied to derive the definition of fractional derivative operator. Fractional generalization of concept of stability is considered.
متن کاملWhich is which and who is who: Roger Waters up against Media
Pink Floyd was a British band whose work began in the late 60s. Roger Waters, the main contributor of the band, wrote almost all the lyrics and was also a main figure behind producing the motion picture of the album. He deliberately attacks Western media in both the lyrics he has written for the band and his solo projects. The present study finds this tendency of assaulting the media deeply roo...
