Laser induced resonance energy transfer — a novel approach towards achieving high sensitivity in capillary electrophoresis Part B: Applications for environmental testing

Autor: Anthony O. Okorodudu, Amin A. Mohammad, M. G. Bissell, John R. Petersen

Publikováno v: Journal of Chromatography A. 767:217-221

Capillary electrophoresis with laser induced resonance energy transfer detection is used for direct determination of ethylenediamine tetraacetic acid (EDTA), 1,2-diaminopropane-N,N,N′,N′-tetraacetic acid (DPTA) and (±)- trans -1,2-diaminocyclohe

STAT Turnaround Time: Satellite and Point-to-Point Testing

Autor: John R. Petersen, Anthony O. Okorodudu, James E. Burchfield, Helen Summers, M. G. Bissell, Amin A. Mohammad

Publikováno v: Laboratory Medicine. 27:684-688

In late 1993, we decentralized critical care and emergency room (ER) laboratory testing services at our institution. An institutionalpolicy that limits patients’ total length of stay in the ER to 4 hours prompted this change, as did continued compl

Steroid analysis by micellar electrokinetic capillary chromatography

Autor: A A, Mohammad, J R, Petersen, M G, Bissell

Publikováno v: Methods in molecular medicine. 27

From the clinical perspective, steroids have always held a great deal of interest, since they are highly specific in their function. They do not have a general or systemic effect, but instead regulate specific physiological functions, such as sex dif

Publikováno v: Clinical Chemistry. 43:1801-1803

Measurement of 24-h urinary free cortisol (UFC) provides the most sensitive and specific diagnostic information for adrenal malfunctions, especially for Cushing syndrome (1)(2). The existing methodologies include immunoassays (3)(4)(5) and HPLC, with
