A dinuclear copper(II) complex with photoswitchable catechol oxidation activity.

In this study, we report the first example of a photoswitchable copper complex with catechol oxidase activity. The distance between the two copper centres is optimal for catalytic catechol oxidation in the -configuration. Thus, the activity of the catalyst is increased compared to its -configuration.

A reliable approach for sequencing clone-specific CDRIII regions in B-cell lymphoma.

We report a reliable approach for sequencing lymphoma-specific CDRIII regions. CDRIII regions present in DNA prepared from routinely fixed and paraffin-embedded diagnostic lymph node material were amplified by the use of consensus VH and JH primers via PCR. PCR products were subcloned directly, without purification or modification of PCR fragments.

In situ amplification of single copy gene segments in individual cells by the polymerase chain reaction.

A method is described using the polymerase chain reaction (PCR) to amplify defined nucleic acid strands in individual cells in situ in conventional smears of bone marrow and peripheral cells. Using radioactively labeled precursors, the incorporation into newly synthesized strands by PCR can be detected by microautoradiography. The specificity of the method can be monitored by gel electrophoresis of the material shed into the reaction mixture.
