    Qiagen nextal qia1
    On the left, calculated effective UV excitation spectra for three different cover materials and for the same crystal of glucose isomerase are shown. On the right, fluorescence images collected with a CCD camera of a glucose isomerase crystal in a <t>Nextal</t> <t>QIA1</t> µplate are shown when exciting with the spectra on the left. The exposure time was kept constant for all three cases to allow a 1:1 comparison. ( a ) The sample was covered with a quartz cover slip. ( b ) Sample covered with polymer film. The fluorescence of the crystal appears not to be degraded by use of the cover film, which can be understood by the similarity of the excitation spectra. ( c 2.3, the protein concentration varies between the four evaluated samples.

    Figure Lengend Snippet: On the left, calculated effective UV excitation spectra for three different cover materials and for the same crystal of glucose isomerase are shown. On the right, fluorescence images collected with a CCD camera of a glucose isomerase crystal in a Nextal QIA1 µplate are shown when exciting with the spectra on the left. The exposure time was kept constant for all three cases to allow a 1:1 comparison. ( a ) The sample was covered with a quartz cover slip. ( b ) Sample covered with polymer film. The fluorescence of the crystal appears not to be degraded by use of the cover film, which can be understood by the similarity of the excitation spectra. ( c 2.3, the protein concentration varies between the four evaluated samples.

    Article Snippet: Three different multi-well plates were used for the experiments: the Nextal QIA1 µplate (Qiagen; catalogue No. 132041), the Greiner 288 low-birefringence (lbr) plate (Greiner; catalogue No. 609820) and the Linbro 24 plate (Jena Bioscience; catalogue No. CPL-101).

    Techniques: Fluorescence, Protein Concentration

    Examples of a variety of different protein and salt crystals in various plates under both white-light and UV illumination. A1–D2 are in sitting drops and E1–H2 are in hanging drops. A1, lysozyme crystal in a Greiner 288 low-birefringence (lbr) plate covered with transparent film and illuminated with UV light. A2, the same illuminated with white light. B1, a mistletoe lectin I crystal in a Greiner 288 lbr plate illuminated with UV light. B2, the same with white light. C1 and C2 show a potassium phosphate crystal in a Greiner 288 lbr plate illuminated with UV and white light, respectively. D1 and D2 show another example of a salt crystal in a Nextal QIA1 µplate illuminated with UV light and white light, respectively. E1, thaumatin crystals applying the hanging-drop method in a Linbro 24 plate covered with siliconized cover slips and illuminated with the filtered mercury arc lamp UV spectrum. E2, the same crystals illuminated with white light. F1, mistletoe lectin I crystals grown in hanging drops illuminated with UV light. F2, the same crystals illuminated with white light. G1, protein crystals of glycerinaldehyde-3-phosphate dehydrogenase grown in a hanging drop on a Linbro 24 plate illuminated with UV light. G2, the same crystals illuminated with white light. The drop contains 5.9%( w / v ) PEG 4000 as precipitant in an acetate buffer. H1, a protein crystal underneath a shower of ammonium sulfate crystals that fluoresces under UV-light illumination but is invisible under polarized white-light illumination (H2). Without UV illumination, this protein crystal would most probably not have been detected.
