Engineering ClpS for Selective and Enhanced N-terminal Amino Acid Binding

March 1, 2019
Author(s)
Jennifer A. Tullman, Zvi Kelman, John P. Marino
One of the central challenges in the development of single-molecule protein sequencing technologies is achieving high-fidelity, sequential recognition and detection of specific amino acids that comprise the peptide sequence. An approach towards achieving

Comparison of volumetric and bead-based counting of CD34 cells by single-platform flow cytometry

February 20, 2019
Author(s)
Luisa Saraiva, Lili Wang, Martin Kammel, A. Kummrow, E Atkinson, J Y. Lee, B Yalcinkaya, M Akgoz, A Ruf, A Engel, Yu-Zhong Zhang, O O''Shea, M P. Sassi, C Divieto, T Lekishvili, J J. Campbell, Y Liu, J Wang, R Stebbings, Adolfas Gaigalas, P Rigsby, J Neukammer, S Vessillier
Background: Over 2000 people a year in the UK need a bone marrow or blood stem cell transplant. It is important to accurately quantify the haematopoietic stem cells to predict whether the transplant will be successful in replenishing the immune system

Proceedings of the First Workshop on Standards for Microfluidics

January 28, 2019
Author(s)
Darwin R. Reyes-Hernandez, Henne van Heeren
In the last two decades, the microfluidics/lab-on-a-chip field has evolved from the concept of micro total analysis systems, where systems with integrated pretreatment and analysis of chemicals were envisioned, to what is known today as lab-on-a-chip

CrowdVariant: a crowdsourcing approach to curate copy number variants

January 6, 2019
Author(s)
Justin M. Zook, Marc L. Salit, Peyton Greenside, Ryan Poplin, Mark DePristo, Madeleine Cule
Copy number variants (CNVs) are an important type of genetic variation and play a causal role in many diseases. However, they are also notoriously difficult to identify accurately from next-generation sequencing (NGS) data. For larger CNVs, genotyping

Cooperative Dynamics in a Model DPPC Membrane Arise from Membrane Layer Interactions

December 19, 2018
Author(s)
Kiley Kennedy, Neha Shafique, Jack F. Douglas, Francis W. Starr
The dynamics of model membranes can be highly heterogeneous, especially in more ordered dense phases. Experimentally, monolayers are often studied as a model system to infer the properties of membranes. To better understand the origins of this

Innovative Approaches to Combat Healthcare-Associated Infections Using Efficacy Standards Developed Through Industry and Federal Collaboration

October 5, 2018
Author(s)
Dianne L. Poster, Carl C. Miller, Yaw S. Obeng, Michael T. Postek, Troy E. Cowan, Richard A. Martinello
Nation-wide, healthcare-associated infections (HAIs) infect one in every 25 hospital patients, account for more than 100,000 deaths and increase medical costs by around $96-147B, each year. Ultraviolet-C (UV-C) antimicrobial devices are shown to reduce the

Combinatorial Cassettes for Higher-Throughput Screening of Osteogenesis

October 4, 2018
Author(s)
Carl G. Simon Jr., Subhadip Bodhak, Hariharan K. Iyer, Luis Fernandez de Castro Diaz, Pam Robey, Azusa Maeda, Sergei Kuznetsov
Animal models are the most biologically relevant method for measuring the osteogenic capability of bone graft formulations. However, animal experiments are slow, tedious and the results can be highly variable, even when conducted within the same lab. In
