Extracellular-Vesicle Isolation from Different Biological Fluids by Size-Exclusion Chromatography.
Current protocols in stem cell biology, 2019This unit describes how to isolate extracellular vesicles (EVs) from different biological fluids using size-exclusion chromatography (SEC) and how to prepare your starting sample and the EV product for downstream applications.

Stress Biomarkers in Biological Fluids and Their Point-of-Use Detection.
ACS Sensors, 2018Hormones produced by glands in the endocrine system and neurotransmitters produced by the nervous system control many bodily functions. The concentrations of these molecules in the body are an indication of its state, hence the use of the term biomarker.

Biomarker discovery in biological fluids
Methods, 2005Discovery of novel protein biomarkers is essential for successful drug discovery and development. These novel protein biomarkers may aid accelerated drug efficacy, response, or toxicity decision making based on their enhanced sensitivity and/or specificity.

Determination of cycloleucine in biological fluids
Analytical Biochemistry, 1969Abstract A method for quantitation of cycloleucine in biological fluids is described. Cycloleucine is oxidized to cyclopentanone by ninhydrin. The cyclopentanone formed is extracted into chloroform and determined by GLC. The method is accurate, convenient, rapid, and free of interference by other constituents of urine or serum.

The determination of deuterium in biological fluids
Analytical Biochemistry, 1961Summary Simple spectrophotometric methods for the analysis of deuterium in biological fluids are described. The methods cover the entire range from 0 to 100 atom % D2O, and micro amounts of sample may be analyzed directly. Results obtained with urine, serum, distillate, and water of combustion samples are presented.

Amitriptyline and metabolites in biological fluids
Forensic Science, 1974Abstract This paper presents separation, identification and measurement techniques for amitriptyline and its metabolites. The methods are applied to samples from subjects exposed to amitriptyline. The subjects fall into three groups, namely those with fatal poisoning, toxic symptoms and long-term therapeutic exposure.

The determination of glycine in biological fluids
Clinica Chimica Acta, 1970Abstract A colorimetric-fluorometric method for the determination of glycine in biological fluids is described. In brief, this procedure involves the degradation of glycine, in protein-free filtrates, to formaldehyde by chloramine T. The formaldehyde is then converted to 3,5-diacetyl- i ,4-dihydrolutidine by Hantzsch reaction in which acetyl acetone ...

The attenuation of ultrasound in biological fluids
The Journal of the Acoustical Society of America, 1984We have measured the ultrasonic attenuation parameters α0 and n of several biological fluids in vitro in the frequency range 2.8–6.8 MHz, using frequency shift and/or a sinc (⋅) sidelobe ratio technique. The parameters α0 and n describe the frequency-dependent attenuation via a power-law model, i.e., α( f)=α0 f n, where f is frequency.
