Crystal structure of a methine dye, C.I. Disperse Blue 354.
Crystals of C.I. Disperse Blue 354, a commercial methine disperse dye, were grown from an ethyl acetate and the crystal structure was determined. Results show that two aromatic planes are effectively coplanar with the dihedral angle of 10.61(11) degrees. The dicyanomethylene group is slightly twisted and two n-hexyl groups tend to be separated with one alkyl group being at the level of the arom...
متن کاملPrimary inducible fluorescence in secretory granules of tumor cells supravitally stained by a toluidine blue dye.
In a toluidine blue dye (British Drug Houses, batch no. 651880), we report a purple chromato graphic fraction (Rf—0,55) with a spectral absorption peak at 622 m/u, which has the property to induce immediate bright yellow fluorescence (primary inducible fluorescence) in cytoplasmic gra nules of tumor cells. The cells are unfixed, supravital stained and examined by fluorescence micro scopy. Th...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولSTUDIES ON NUCLEIC ACID METACHROMASY II. Metachromatic and Orthochromatic Staining by Toluidine Blue of Nucleic Acids in Tissue Sections
Acrolcin-fixed, polyester wax-cmbcddcd tissue sections showed excellent preservation of light microscopic architecture and, when stained with toluidinc blue, intense color contrast between DNA, which stained orthochromatically, and RNA, which stained metachromatically. This method has practical value for differentiating DNA from RNA in the same section. The color c~)ntrast was impaired by subst...
