Abstract
The extracellular domain of the neurotrophin receptor p75 has been shown to be a prominent biomarker for both disease diagnosis and progression for amyotrophic lateral sclerosis. This urinary analyte may serve as a valuable fluid biomarker which greatly increases the ease of sample collection in both healthy volunteers and patients. In this paper, the method development and validation for an electrochemiluminescence assay is described. This assay completely uses commercially available reagents and can be performed using common lab equipment found in most bioanalytical labs. This method shows good accuracy and precision, high sensitivity as well as good parallelism illustrating the ability of the method to detect and report on urinary concentrations of neurotrophin receptor p75. The assay can quantitate as low as 78 pg/mL of neurotrophin receptor p75 and > 98% of healthy urine samples tested fell within the dynamic range of the assay.

期刊介绍：
Reliable data obtained from selective, sensitive and reproducible analysis of xenobiotics and biotics in biological samples is a fundamental and crucial part of every successful drug development program. The same principles can also apply to many other areas of research such as forensic science, toxicology and sports doping testing.
The bioanalytical field incorporates sophisticated techniques linking sample preparation and advanced separations with MS and NMR detection systems, automation and robotics. Standards set by regulatory bodies regarding method development and validation increasingly define the boundaries between speed and quality.
Bioanalysis is a progressive discipline for which the future holds many exciting opportunities to further reduce sample volumes, analysis cost and environmental impact, as well as to improve sensitivity, specificity, accuracy, efficiency, assay throughput, data quality, data handling and processing.
The journal Bioanalysis focuses on the techniques and methods used for the detection or quantitative study of analytes in human or animal biological samples. Bioanalysis encourages the submission of articles describing forward-looking applications, including biosensors, microfluidics, miniaturized analytical devices, and new hyphenated and multi-dimensional techniques.
Bioanalysis delivers essential information in concise, at-a-glance article formats. Key advances in the field are reported and analyzed by international experts, providing an authoritative but accessible forum for the modern bioanalyst.
