Analytical Procedure for the Determination of Doxycycline Residues in Animal Tissues by Liquid Chromatography

A sensitive liquid chromatographic method for the determination of doxycycline in animal tissues has been prepared and validated. The extraction of the analyte from biological matrix was performed with the solution of oxalic acid and ethyl acetate. The samples were cleaned up by solid phase extraction (SPE) procedure using a carboxylic acid cartridge. Chromatographic separation was carried out ...

Phosphorus Compounds in Animal Tissues

The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...

Deoxyribosyl compounds in animal tissues.

Several types of deoxyribosyl compounds have been found in the acidsoluble fraction of normal and malignant tissues (l-8). In 1955 Potter and Schlesinger (1) reported the isolation of deoxynucleoside mono-, di-, and triphosphates from extracts of calf thymus. More recently LePage (7) reported the isolation of deoxyadenosine triphosphate from a tumor. Schneider (2), using a microbiological assay...

An Overview on Recent Progress in Electrochemical Biosensors for Antimicrobial Drug Residues in Animal-Derived Food

Anti-microbial drugs are widely employed for the treatment and cure of diseases in animals, promotion of animal growth, and feed efficiency. However, the scientific literature has indicated the possible presence of antimicrobial drug residues in animal-derived food, making it one of the key public concerns for food safety. Therefore, it is highly desirable to design fast and accurate methodolog...
