Platelet-endothelial cell tetra-span antigen (PETA-3) was originally identified as a novel human platelet surface glycoprotein, gp27, which was detected by a monoclonal antibody (MoAb), 14A2.H1. Although this glycoprotein is present in low abundance on the platelet surface, MoAb 14A2.H1 stimulates platelet aggregation and mediator release. We now report isolation of a cDNA clone encoding PETA-3...

The double-bond conversion of UV-cured resins prepared from pentaerythritol triacrylate (PETA) was determined by pyrolysis-gas chromatography in the presence of an organic alkali, tetramethylammonium hydroxide (TMAH). The pyrogram of the uncured prepolymer compound, consisting of PETA and a photoinitiator, 2,2-dimethoxy-2-phenylacetophenone, contained specific products reflecting the original a...

The genes encoding cytochrome f (petA), cytochrome b(6) (petB), the Rieske FeS-protein (petC), and subunit IV (petD) of the cytochrome b(6)f complex from the thermophilic cyanobacterium Synechococcus elongatus were cloned and sequenced. Similar to other cyanobacteria, the structural genes are arranged in two short, single-copy operons, petC/petA and petB/petD, respectively. In addition, five op...

We isolated seven allelic nuclear mutants of Chlamydomonas reinhardtii specifically blocked in the translation of cytochrome f, a major chloroplast-encoded subunit of the photosynthetic electron transport chain encoded by the petA gene. We recovered one chloroplast suppressor in which the coding region of petA was now expressed under the control of a duplicated 5' untranslated region from anoth...

In a few short years, computers capable of over one Petaflops performance will become a reality. The most likely approach for first successfully reaching this performance level will involve several thousands of parallel processing elements. What are the key considerations for building such systems? What are the software requirements and demands? How will applications scale? How reliable are the...

A monolithic stationary phase was prepared for liquid chromatography by in situ copolymerization of pentaerythritol triacrylate (PETA) and triallyl isocyanurate (TAIC). The morphology of monolithic column and pressure drop across the column were characterized. The effect of the porogen on the pore structure was characterized by SEM. Under the comparison condition, the monolith was suceessfully ...

Molecularly imprinted polymers (MIPs) were fabricated on glass slides with a "sandwich" technique giving ~20 µm thick films. Methanol/water as a solvent, and polyethyleneglycol and polyvinylacetate as solvent modifiers, were used to give a porous morphology, which was studied with scanning electron microscopy and gravimetric analysis. Various MIPs were synthesized through non-covalent imprintin...
