DNA extraction with organic solvents in gel barrier tubes.
The extraction of nucleic acids with phenol and chloroform is the standard method to remove proteins and lipids from cellular digests. A major drawback to the use of these organic solvents is their caustic and toxic qualities. Phenol can cause severe burns while chloroform is hepatotoxic and carcinogenic. We describe in this paper the use of a special blood collection tube to isolate the offens...
متن کاملPredicting Solubility of Isotactic Poly (1-Butene) in Different Organic Solvents by Modified UNIQUAC
The UNIQUAC activity coefficient model is extended to predict solid-liquid equilibrium of isotactic crystalline poly (1-butene), iPBu-1, in different organic solvents. The UNIQUAC activity coefficient model used in this work is based on the concept of group contribution and consists of combinatorial, residual and free volume terms. To account for branching of atom groups in the monomer structur...
متن کاملChemiluminescence Properties of Peroxyoxalate System in Organic Solvents
Peroxyoxalate system includes an oxalate ester, peroxide and a fluorescer, The energy resulted from the reaction of oxalate ester and peroxide is transferred to fluorescer and cause it to fluorsc. The effect of reactants chemical structure, their concentration, solvent media (polarity and viscosity) and the temperature, on the intensity of the illuminated light with respect to time have bee...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولStability of M13 Phage in Organic Solvents
The effect of different types of organic solvents on the structural integrity of M13 phages has been directly visualized by transmission and scanning electron microscopy. The exposure of M13 phages to apolar hexane had no effect on the structure of the phages for up to 8 h. In contrast, phages showed ~10-fold contraction into rod-like I-forms and to flattened spheroids with ~12 nm diameter upon...
