Quantitation of DNA and RNA with absorption and fluorescence spectroscopy.
Quantitation of nucleic acids is a fundamental tool in molecular biology that requires accuracy, reliability, and the use of increasingly smaller sample volumes. This unit describes the traditional absorbance measurement at 260 nm and three more sensitive fluorescence techniques, as well as three microvolume methods that use fiber optic technology in specialized cells or instrumentation. These ...
متن کاملIn vitro study of drug-protein interaction using electronic absorption, fluorescence, and circular dichroism spectroscopy
In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...

گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
Vitamin C Supplements Influence Zinc Uptake and Distribution in Rats
Wistar rats were fed for 28 d a diet comprising vitamin C administered in drinking water in a concentration of 1g/L, concomitantly with traces of zinc 65 given intragastrically. The body weight gains, organ to body ratios, blood values, and carcass and organ concentrations of zinc 65 were examined within 28 days postdosing. The supplement of vitamin C decreased significantly zinc 65 carcass ret...
متن کاملDetermination of Insulin Concentration in Camel Milk Using Ultra Violet –Visible Absorption Spectroscopy
ABSTRACT: Camel milk contains sufficient levels of insulin and does not form the coagulum in the stomach preventing degradation of insulin and act as an effective vehicle to take the milk insulin unchanged to the intestine. In present study direct spectroscopy and standard addition method, well-known methods in analytical chemistry were used for determining insulin concentration in camel milk. ...
