Standard Reference Material 2378 Fatty Acids in Frozen Human Serum. A Clinical SRM based on Endogenous Supplementation of Polyunsaturated Fatty Acids

February 13, 2018
Author(s)
Bruce A. Benner Jr., Michele M. Schantz, Johanna Camara, Katherine E. Sharpless, James H. Yen, Lorna T. Sniegoski, Carissa D. Powers, Rosemary L. Schleicher
Dietary fatty acids can be both beneficial and detrimental to human health depending on the degree and type of saturation. Healthcare providers and research scientists monitor the fatty acid content of human plasma and serum as an indicator of health

Effects of Distal Residues Mutations on the Structure, Dynamics and Catalysis of Human Monoacylglycerol Lipase

January 29, 2018
Author(s)
Sergiy Tyukhtenko, Girija Rajarshi, Ioannis Karageorgos, Nikolai Zvonok, Elyssia S. Gallagher, Hongwei Huang, Kiran Vemuri, Jeffrey W. Hudgens, Alexandros Makriyannis
An understanding of how conformational dynamics modulates function and catalysis of human monoacylglycerol lipase (hMGL), an important pharmaceutical target, can facilitate the development of novel modulatory ligands. Here, we report the discovery and

Recommendations for assessing commutability part 1: general experimental design

January 18, 2018
Author(s)
Johanna Camara, W. Greg Miller, Schimmel Heinz, Neil Greenberg, Chris Burns, Vincent Delatour, Mauro Panteghini, Hubert W. Vesper, Robert Rej, Ferruccio Ceriotti, Gerhard Schumann, Jeffrey R. Budd, Weykamp Cas, Goran Nilsson, Finlay MacKenzie, Thomas Keller
Commutability is a property of a reference material that relates to the closeness of agreement between results for a reference material and results for clinical samples when measured by two or more measurement procedures. Commutability of reference

Recommendations for assessing commutability part 2: based on the difference in bias between a reference material and clinical samples

January 18, 2018
Author(s)
Johanna Camara, Goran Nilsson, Jeffrey R. Budd, Neil Greenberg, Vincent Delatour, Gerhard Schumann, Robert Rej, Mauro Panteghini, Ferruccio Ceriotti, Schimmel Heinz, Weykamp Cas, Thomas Keller, Chris Burns, Finlay MacKenzie, W. Greg Miller
A process is described to assess the commutability of a reference material intended for use as a calibrator, trueness control or external quality assessment sample based on the difference in bias between a reference material and clinical samples measured

Recommendations for assessing commutability part 3: based on the calibration effectiveness of a reference material

January 18, 2018
Author(s)
Johanna Camara, Weykamp Cas, Goran Nilsson, Robert Rej, Finlay MacKenzie, Ferruccio Ceriotti, Neil Greenberg, Schimmel Heinz, Gerhard Schumann, Thomas Keller, Vincent Delatour, Mauro Panteghini, Chris Burns, W. Greg Miller
A process is described to assess the commutability of a reference material intended for use as a calibrator based on its ability to fulfill its intended use in a calibration traceability scheme to produce equivalent clinical sample results among different

Quantitative analysis of the impact of a human pathogenic mutation on the CCT5 chaperonin subunit using a proxy archaeal ortholog

December 1, 2017
Author(s)
Darion Spigolon, David Travis Gallagher, Adrian Velazquez-Campoy, Donatella Bulone, Jatin Narang, Pier San Biagio, Francesco Cappello, Alberto J. Macario, Everly Conway de Macario, Frank Robb
The human chaperonin complex is a 1 MDa nanomachine composed of two octameric rings formed from eight similar but non-identical subunits called CCT. Here, we are elucidating the mechanism of a heritable CCT5 subunit mutation that causes profound neuropathy

Tissue Inhibitor of Metalloprotease-2: bioprocess development, physicochemical, biochemical and biological characterization of highly expressed recombinant protein

December 1, 2017
Author(s)
Ananda Chowdhury, Robert G. Brinson, Beiyang Wei, William G. Stetler-Stevenson
Tissue Inhibitor of Metalloprotease -2 (TIMP-2) is a secreted, 21 kDa, multifunctional protein. It was first described as an endogenous inhibitor of matrix metalloproteases (MMPs) that prevents protease-mediated breakdown of the extracellular matrix often

Quantitative Fluorescence Measurements with Multicolor Flow Cytometry

November 20, 2017
Author(s)
Lili Wang, Adolfas K. Gaigalas, James Wood
Multicolor flow cytometer assays are routinely used in clinical laboratories for immunophenotyping, monitoring disease and treatment, and determining prognostic factors. However, existing methods for quantitative measurements have not yet produced
