The lipid solution is transferred to containers and frozen by placing the containers on a block of dry ice or swirling the container in a dry ice-acetone or alcohol (ethanol or methanol) bath. (sigmaaldrich.com)
In vitro assay showed dose-dependent antibacterial activity of the methanol, aqueous and chloroform (but not petroleum ether) extracts of the two plant roots. (bvsalud.org)
Insoluble1
It is practically insoluble in chloroform and 1 in 0.5 soluble in water at 20°C. Sucrose has a high degree of stability at room temperature. (uspharmacist.com)
Lipid3
Prepare a lipid stock solution (1 mg/ml) in chloroform:methanol (2:1 v/v). (avantilipids.com)
A control group including two patients with warts and two with corns were treated with a 2:1 ratio of chloroform and methanol solution (the lipid solvent) for a period of 20 days to eliminate the possibility that the treatment results were affected by the solvent. (wakeup-world.com)
If the use of chloroform is objectionable, an alternative is to dissolve the lipid(s) in tertiary butanol or cyclohexane. (sigmaaldrich.com)
Solvent1
Conformational equilibria were dependent on the solvent of choice, either methanol-d(4) or chloroform-d, with mainly C-4(1) and C-1(4) conformations present but also skew conformations to some extent. (lu.se)
Extract3
In previous research, the authors demonstrated that the methanol extract of Artemisia vulgaris (AVM) has the ability to inhibit chronic myeloid leukemia (CML) cell proliferation. (spandidos-publications.com)
In previous research, the authors demonstrated that the methanol extract of A. vulgaris (AVM) has the ability to inhibit the viability of CML cells ( 10 ). (spandidos-publications.com)
at these time points, all of the radiolabel in the chloroform/methanol extract of the ipsilateral dorsal root ganglia was present in phosphatidylcholine. (epa.gov)
Hexane2
Separation of the n-hexane fraction using silica gel column chromatography yielded the chloroform:methanol (50:1) fraction, which showed the highest tyrosinase inhibitory activity. (ijpsonline.com)
The results demonstrated that the ethyl acetate and chloroform fractions were more effective than the n‑hexane and water fractions. (spandidos-publications.com)
Phytochemical screening of methanol and aqueous extracts of roots yielded flavonoids, tannins, saponins, and sugars. (stuartxchange.org)
Precipitation1
We found that precipitation with chloroform/methanol/water results in fast, efficient preparation of VP samples, allowing 100% and 99.2% amino acid sequence coverage of VP1 for trypsin and Asp-N digestion, respectively. (lonza.com)
Lipids2
The macroalgae lipids were extracted with chloroform:methanol (2:1 -vol/vol) mixture. (helsinki.fi)
Total lipids were extracted with chloroform: methanol (2:1) [2]. (vin.com)
Extraction1
The amount of chicken fat was estimated by emulsification and chloroform/methanol extraction. (nih.gov)
Mixture1
Synthesis of indophenazine derivatives was achieved by refluxing an equimolar (0.01 mol) mixture of formaldehyde, active hydrogen compounds (sulphanilamide, sulphadimidine, sulphamethoxazole, 2−aminopyridine, pthalamide, benzamide, nicotinamide, anthranilic acid and 2−marcapto−benzimidazole) and Indophenazine with methanol for 3 h (Scheme 1).

Standard2
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. (lookchem.com)
The started in 1953 in the north-east of the smears were fixed in methanol, stained by country [ 8 ] but, while it was extended to standard Giemsa methods and examined other parts of the country, the isolation and for parasites by light microscope at high characterization of the parasites has not magnification (× 1000).
