To 5 mg of F-21-HS, 200 [micro]L of dimethyl formamide, 200 [micro]L of dioxan, and 100 [micro]L of distilled water containing 10 mg of N-hydroxysuccinimide and 20 mg of 1-ethyl-3-(3-dimethyl-amino-propyl) carbodiimide-HCL were added; the reaction mixture was vortex-mixed and kept overnight at 4 [degrees]C.
Results: The results of the research will provide data for mapping structure-activity relationships among novel formamide fungicides.
Table 2 lists the contact angles between double-distilled water, ethylene glycol, glycerol or formamide and poly(amic acid) and polyimide samples both, before and after plasma treatment.
(5b) a mixture of chloroform/alcohol with weight ratio 3:1, (5c) mixture of chloroform/tetrachloromethane with weight ratio 3:1, and (5d) mixture of chloroform/N,N-dimethyl formamide (DMF) with weight ratio 3:1.
The multiplex samples were prepared for analysis on the ABI genetic analyzer by adding 2 [micro]L of the post-PER to 9 [micro]L of formamide. Multiplex analysis performed on the ABI 310 capillary electrophoresis unit detected five wild-type samples (Fig.
peroxide (DCP, the initiator) and dimethyl formamide (DMF, the inhibitor) supplied by Fluka Co.
The DNA fragments were diluted 10-fold (with HEX-labeled products) or 20-fold (with 6-FAM- or TET-labeled products) and were then mixed with formamide and GS-500 TAMRA size standard (Applied Biosystems).
The NCO-terminated PU with various macroglycol diols (PTMG 2000, PBA 2000) was prepared in dimethyl formamide (DMF).
Recently, we developed an accelerated procedure for the synthesis of formamides. It was important to investigate if the procedure can be successfully applied for the synthesis of 1-phenylethylformamides with electron-donating substituents, for example N-[1-(4-methoxyphenyl) ethyl] formamide.
Aliquots (25 [micro]L) of the denatured, neutralized amplicon were then combined with 100 [micro]L of hybridization solution [1.5X standard saline citrate (1X = 0.15 mol/L NaCI and 0.015 mol/L sodium citrate), 1 g/L sodium dodecyl sulfate, and 150 mL/L deionized formamide in 0.5 mol/L sodium phosphate buffer, pH 4.2] in each of four wells coated with the two probes, in duplicate.
A 100-ng sample of control or tumor DNA was amplified in the presence of 0.4 [micro]mol/L each oligonucleotide primer and 1 U of Taq polymerase (Cetus-Perkin-Elmer) in a final volume of 25 [micro]L of the following solution: 200 [micro]mol/L each dNTP (Promega), 1.5 mmol/L Mg[Cl.sub.2], 50 mL/L deionized formamide (Sigma), 0.166 mmol/L ([NH.sub.4])S[O.sub.4], 67 mmol/L Tris-HCl, pH 8.8, 0.1 mL/L Tween-20.
