    Notes: Summary We have recorded the direction of optokinetic nystagmus (OKN) elicited by moving plaid patterns in order to dissociate the pathways that mediate horizontal OKN. The plaids used comprised two drifting sinusoidal gratings arranged such that their individual directions of drift were very different from the direction of coherent motion of the overall pattern. The direction of OKN with binocular viewing was close to the mean of the component directions, suggesting a dominant influence of cortical visual neurons that respond to oriented one-dimensional components of the image. But the direction of OKN was consistently shifted slightly towards the direction of motion of the overall pattern, suggesting a secondary influence responsive to pattern direction. OKN recordings obtained during monocular viewing suggest that this secondary influence reflects the direct retinal pathway to the brainstem structures mediating OKN.

    R-phycoerythrin from the macroalgaCorallina officinalis (Rhodophyceae) and application of a derived phycofluor probe for detecting sugar-binding sites on cell membranes (1991)

    Notes: Abstract R-Phycoerythrin (absorption spectrum 280; 495;sh 535, 564 nm with A564/A280 ratio of 5.3) was purified from the red macroalgaCorallina officinalis. The relative molecular mass determined from PAGE was 240 000. SDS-PAGE demonstrated two major subunits ofM r 20 000 and 21 000, respectively, and a minor subunit ofM r 30 000. A fucospyranosyl phenylisothiocyanate conjugate was prepared and this novel fluorescent affinity reagent used in conjunction with a flow cytometer to probe fucose-binding sites on blood mononuclear cells. By varying the sugar and using other phycobiliproteins the approach has the potential for simultaneously monitoring different sugar binding sites on subsets of cells within populations.
