All of the precipitation methods used gave products which were closely similar in terms of M n, but precipitation with HCl/acetone and HAc/ethanol gave low yields (25 and 3%, respectively).doi:10.1016/0144-8617(84)90015-8E. Balabanova-Radonova...
(Quantos, Mettler Toledo). The precursor powders are then mixed thoroughly with ethanol and ten 5-mm ZrO2balls in a dual asymmetric centrifuge (Smart DAC250, Hauschild) for 9 min. To ensure proper slurry viscosity, the ethanol amount is automatically calculated on the basis of the amount ...
The digested DNA was concentrated by ethanol precipitation and dissolved in 200 μL of TE8 (10 mM Tris-HCl, 1 mM EDTA, pH 8). Finally, 5 μL of the 100 bp DNA ladder was subjected to DNA electrophoresis on 2% agarose or 12% acrylamide gels containing ethidium bromide. An...
Antibiotic powders were dissolved in deionized water except chloramphenicol (ethanol) and meropenem (deionized water with 10.4 mg/ml of sodium carbonate). All of them were filter-sterilized (0.2 μm) before storage. Meropenem and colistin agar plates were used within two days from preparation. ...
Many laboratories use water for cleaning and avoid the use of ethanol or other sanitizers, simply to avoid the possible consequences of embryotoxicity; others use hydrogen peroxide. Although products specifically for ART laboratories are available on the market, care must be taken to assure that ...
(b) Give two examples of two situations that will result in white colonies. Can the EMIT be used to measure the concentration of drugs in urine samples? Explain. What are the tests that can be conducted to determine the presence of ethanol? What would be an appropriate negative control ...
1. Please add proper volume ethanol to the bottles labeled Buffer RW and 70% ethanol before starting. Mix well and check bottles to indicate that the ethanol has been added. 2. All reagents should be clear. In case, some may form precipitate due to low ...
Surgical anesthesia may be divided into five parts: (1) pre-anesthetic preparation including the selection of an anesthetic candidate and its preparation for anesthesia/surgery; (2) anesthetic induction, as the process by which a conscious animal is rendered unconscious; (3) anesthetic maintenance, ...
