Light sheet microscopy became a powerful tool in life sciences. Often, however, the sheet geometry is fixed, whereas it would be advantageous to adjust the sheet geometry to specimens of different dimensions. Therefore we developed an afocal cylindrical zoom lens system comprising only 5 lenses and a total system length of less than 160 mm. Two movable optical elements were directly coupled, so...

Heparin-binding growth-associated molecule (HB-GAM) is an extracellular matrix-associated protein implicated in the development and plasticity of neuronal connections of brain. Binding to cell surface heparan sulfate is indispensable for the biological activity of HB-GAM. In the present paper we have studied the structure of recombinant HB-GAM using heteronuclear NMR. These studies show that HB...
