Size exclusion chromatography (SEC) is a chromatographic method in which particles are separated based on their hydrodynamic vol- ume. When the separation medium is a gel, the technique is known as gel permeation chroma- tography (GPC) or gel filtration chromatogra- phy (GFC). Often the terms SEC and GPC are used interchangeably, while GFC is most often used for aqueous chromatography. ...

Is a patient really sick? What medicine is necessary? In what dosage? Is the patient responding to it? Doctors customarily answer these questions based on a variety of symptoms. But many of the symptoms used today, because of their subjective description and uncertain ...
Concern regarding extractables and leachables has been increasing over the past few years, as evidenced by regulatory guidance documents [1-3]. One means of qualifying a component as being suitable for use in a drug product is to determine the extraction profile of that component in multiple solvents with polarities similar to and bracketing that of the product vehicle. Any observed extractables ...
UHPLC often provides run times of less than one minute with peak widths of less than 200 milliseconds, which have created challenges for system performance and detection methods. A variety of applications in the pharmaceutical and environmental areas, using small particle columns, is presented to demonstrate the throughput and performance of the new Nexera UHPLC.
The transition from LC to ultrafast LC reduces some of the limitations normally associated with LC. However, when LC analysis is conducted using an ordinary detector like an absorbance detector, only retention time information can be considered reliable. Using a Mass Spectrometer as an LC detector alleviates this issue, and this paper demonstrates how ultrafast LC/MS significantly enhances LC ...
The requirements for sterile technique depend on the experimental situation including the growth media used, the experimental organism, the duration of the experiment and the intended use of the culture. For these experiments the most serious contaminant is mold. Many common molds grow well on yeast media and compete effectively to over-grow the plates and obscuring the yeasts that do manage to ...
Ribavirin is an antiviral prodrug used for the treatment of Hepatitis C and respiratory syncytial virus (RSV) among other common viruses. A method for the analysis and quantification of ribavirin in rat plasma utilizing HPLC-MS/MS with updated HPLC column technology has been developed and validated according to the FDA guidance to the industry.
The assay displays good linearity with ...
It is well-known that certain cancer cells have a hormone dependence and that earlier diagnosis and treatment of hormonally driven cancers can be based on the chemical profile of a tumor. Estrogens and their metabolites are suspected in the development and growth of certain types of breast cancer. Current analytical methodology limits screening of samples due to the extended analytical times ...
The science, art, and practice of protein purification have been with us for more than a century, yet, in many respects,
the field is only now evolving past its adolescent roots. New methods are replacing old methods at such a dizzying
pace, that even life-long experts in protein purification cannot keep up. In this article, we present many state-of-the-art
protein purification techniques ...
Background: The University of Virginia School of Medicine dis- continued animal vivisection in February 2004 for teaching lifesav- ing procedures to third-year medical students. Consequently, a 1-day course using simulation technology was developed to meet objec- tives previously covered in the animal laboratory. The authors sought to evaluate the course and hypothesized that the students' ...
