Meritec-Strep (Meridian Diagnostics, Inc., Cincinnati, Ohio) a coagglutination method, was compared with Streptex (Wellcome Diagnostics, Research Triangle Park, N.C.), a latex agglutination method, for the identification of beta-hemolytic streptococcal groups A, B, C, F, and G by the direct colony method. A total of 124 beta-hemolytic streptococcal isolates were tested, which included 77 from g...
Pharmacokinetic (PK) and immunohistochemistry (IHC) assays are essential to the evaluation of the safety and efficacy of therapeutic monoclonal antibodies (mAb) during drug development. These methods require reagents with a high degree of specificity because low concentrations of therapeutic antibody need to be detected in samples containing high concentrations of endogenous human immunoglobuli...
Commercially prepared polyclonal antisera to Legionella pneumophila are known to cross-react with organisms of the genus Pseudomonas. To determine whether a commercially available monoclonal antibody reagent specific for L. pneumophila would also cross-react with pseudomonads, a two-laboratory study was undertaken to test both monoclonal and polyclonal reagents against 33 isolates of Pseudomona...
With coagglutination reagents prepared against W antigens, 205 clinical isolates of Neisseria gonorrhoeae were classified into three serogroups WI, WII, and WIII. Of 195 strains isolated from patients who acquired their infection in the Edinburgh area, 85 (44%) belonged to serogroup WI and 110 (56%) to serogroup WII. Serogroup WII accounted for 90% of all isolates from homosexual men and for 34...
The coagglutination (COA) test for the identification of Neisseria gonorrhoeae was compared with immunofluorescence and sugar degradation tests on 1710 gonococcal isolates, 72 of which produce beta-lactamase. The COA test gave a positive result for 98.6% of the strains. Treatment of suspensions with Streptomyces enzyme reduced the incidence of inconclusive results due to autoagglutination to 1....
The rabbit is customarily used for the preparation of anti-human globulin serum, but there are several objections to the choice of this animal. These are: (1) The volume of serum obtained is small. To maintain supplies it is necessary either to have several animals producing the reagent, or to hyperimmunize and bleed the rabbits used too frequently, which in turn results in a less specific reag...
Suzuki-Miyaura (SM) cross-coupling is arguably the most widely-applied transition metal catalysed carbon-carbon bond forming reaction to date. Its success originates from a combination of exceptionally mild and functional group tolerant reaction conditions, with a relatively stable, readily prepared and generally environmentally benign organoboron reagent. A variety of such reagents have been d...
