Utilizing ~1 W of microwave power, we achieved heating of PCR buffer with unprecedented temperature ramp rates that allowed for rapid thermocycling. Polymeric microdevices, chosen for their low cost and ease of fabrication, were constructed from polycarbonate (PC), poly(methyl-methacrylate) (PMMA), and polyester-toner (PeT) using fast, simple microfabrication via computer-aided milling for PC a...

Fig (Ficus carica) trees exhibited symptoms of little leaf, mottling and deformation in Sanliurfa province, Turkey. Poylmerase chain reaction (PCR) through direct nested-PCR, phylogeny based on the sequence analysis revealed that infecting agent was closely related to ‘Candidatus Phytoplasma aurantifolia’ (16SrII-B subgroup). This is first report Ca. P. aurantifolia fig

To the Editor: In recent years, several novel respiratory viruses have been identified. These include human metapneumovirus (HMPV) (1), severe acute respiratory syndrome– associated coronavirus (2), human coronavirus (HCoV) NL63 (3,4), HCoV HKU1 (5), and, most recently, human bocavirus (HBoV) (6). The latter belongs to the Parvoviridae family and is most closely related to bovine parvovirus and...

A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...

Two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. Poly(amide-imide) (PAI) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of N,N´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...

1. Poly(ADP-ribose) synthesized in nuclei isolated from Friend erythroleukemic cells was characterized. Although the activity of poly(ADP-ribose) synthesis of cells induced to differentiate was suppressed to about one-third of that of uninduced cells, the chain length were identical, and were clearly restricted within a narrow band in polyacrylamide gels, moving at about half the speed of bromp...

Diagnostic immunoglobulin (Ig) polymerase chain reaction (PCR) clonality analyses need to be simple, reproducible, and rapid. Sucrose and cresol red (gel loading buffer reagents) were added to a routine IgH PCR reaction mix to obviate the need for adding gel loading buffer separately after PCR amplification. Not only did this decrease the time spent after PCR analysis but also gave similar or e...
