Quality as Clear as Glass – Polarizing Microscopy in Glass Production

Distinction between crystalline inclusions and gas bubbles or processing defects takes place using either automatic inspection and sorting systems or by manual sorting after visual inspection. Segments cut out using a glass cutter or diamond saw can usually be inspected microscopically without further processing. For large, opaque “stones”, the defect is ground and diagnostics are …

FusionOptics – Combines high resolution and depth of field for ideal 3D optical Images

However, the feasibility of this design first had to be reviewed in the light of neurophysiology – whether the brain can process signals that differ greatly between the two eyes into correct three-dimensional images. Earlier studies were primarily concerned with two-dimensional images. Leica Microsystems presented the idea to Dr. Daniel Kiper of the Institute of …

A Comparison of Donor-Acceptor Pairs for Genetically Encoded FRET Sensors: Application to the Epac cAMP Sensor as an Example

We recently reported on CFP-Epac-YFP, an Epac-based single polypeptide FRET reporter to resolve cAMP levels in living cells. In this study, we compared and optimized the fluorescent protein donor/acceptor pairs for use in biosensors such as CFP-Epac-YFP. Our strategy was to prepare a wide range of constructs consisting of different donor and acceptor fluorescent proteins …
