    摘要： Molded articles formed of polystyrene or other polymers containing an aromatic moiety can be derivatized on the surface of the article by subjecting the molded article to a chemical reaction wherein the reaction media utilizes tetramethylsulfone as the reactant solvent and a suitable substituent group which is substituted on to the aromatic moiety of the polystyrene or other polymer by electrophilic substitution. By choosing the substituent group to further include a leaving group, further substitution of the primary substituent can be effected normally by nucleophilic substitution reaction. In this way, biologically important molecules can be attached to a polystyrene or other aromatic containing polymer without effecting certain properties of the molded article such as its optical or spectroscopic clarity.

    摘要： A DNA probe has been isolated which is capable of hybridizing to an oligonucleotide sequence coding for a polypeptide from a major 64 Kilodalton protein of human cytomegalovirus (HCMVgp64). The probe has a sequence of at least seventeen (17) to as many as seven hundred twenty-one (721) nucleotides. The DNA fragments coding for the major late protein of human cytomegalovirus (HCMVgp64) may be hybridized to DNA fragments of HCMV DNA from an individual having human cytomegalovirus infection. The major late protein of human cytomegalovirus (HCMVgp64) also reacts with T-lymphocytes of an individual after natural infection of that individual with human cytomegalovirus. Thus, the HCMVgp64 protein may be used as a vaccine to prevent HCMV infection.
