Abstract:
The 1BL.1RS chromosomal translocation in wheat is the result of replacement of the short arm of chromosome 1B of wheat by the short arm of chromosome 1R of rye, which had been widely used as a parental line in worldwide wheat breeding, resulting in a high percentage of wheat cultivars containing this translocation. A fast and reliable approach to identify this translocation is highly desirable in modern wheat breeding. This study compared reversed-phase ultra-performance liquid chromatography (RP-UPLC), acidic polyacrylamide gel electrophoresis (A-PAGE), liquid chromatography coupled to tandem

Abstract:
A simple, sensitive and accurate RP-UPLC method has been developed for the determination of Linezolid in Tablet formulation. The mix of the Linezolid was found to be 251nm in Acetonitrile: Buffer [40:60(v/v)]. The method shows high sensitivity with linearity 5 to 30μg/ml (regression r2 = 0.999). This method was tested and validated for various parameters according to ICH guidelines and USP. The Detection limit and quantitation limit were found to be 50mg ml–1 and 150 mg ml–1 in Acetonitrile: Buffer [40:60(v/v)] respectively.

Abstract:
Introduction Oligonucleotides are short nucleic acid chains, usually 19-27mer long. They bind to their corresponding chain, making a specific inhibition possible. In pharmaceuticals, this can be used to inhibit the expression of a gene or protein of interest. Oligonucleotides are usually analyzed based on separation using both hydrophobic and ion-exchange properties. In this project, the possibility to use a mixed-mode column to separate these oligonucleotides and their impurities were explored. Method Liquid chromatography is used as the separation method and the method of detection is both m

Slaughterhouse blood is a valuable by-product since multiple bioactive compounds can be derived out of it. Its solid fraction consists mainly of hemoglobin, which is a good source of antimicrobial and antioxidant peptides that can be released by peptic hydrolysis. Nevertheless, this method has limitations such as low yield, expensive cost of enzyme process, and non-eco-friendly production (high energy consumption and chemical reagents requested).
