Described herein is a unique and inexpensive method that outperforms commercial methods that amplify the streptavidin-biotin recognition event. Amplification induced by streptavidin and biotinylated protein causes the formation of a large detectable polymer. This approach enjoys a 100-fold decrease in

Mechanical cues affect many important biological processes in metazoan cells, such as migration, proliferation, and differentiation. Such cues are thought to be detected by specialized mechanosensing molecules linked to the cytoskeleton, an intracellular network of protein filaments that provide mechanical

Cell, 181(6), 1380-1394 (2020-06-06)
Homologous recombination (HR) helps maintain genome integrity, and HR defects give rise to disease, especially cancer. During HR, damaged DNA must be aligned with an undamaged template through a process referred to as the homology search. Despite decades of study

Nature communications, 10(1), 2159-2159 (2019-05-16)
Accurate DNA replication is tightly regulated in eukaryotes to ensure genome stability during cell division and is performed by the multi-protein replisome. At the core an AAA+ hetero-hexameric complex, Mcm2-7, together with GINS and Cdc45 form the active replicative helicase

Cell reports, 26(8), 2113-2125 (2019-02-21)
Progression of DNA replication depends on the ability of the replisome complex to overcome nucleoprotein barriers. During eukaryotic replication, the CMG helicase translocates along the leading-strand template and unwinds the DNA double helix. While proteins bound to the leading-strand template
Peter Rigsby et al.
Biologicals : journal of the International Association of Biological Standardization, 66, 21-29 (2020-06-24)
Typhoid vaccines based on protein-conjugated capsular Vi polysaccharide (TCVs) prevent typhoid in infants and young children. Analysis of the serum anti-Vi IgG response following immunisation against typhoid confirms the immunogenicity of TCVs and forms an important part of the pathway
Yuanchang Zhao et al.
iScience, 9, 502-512 (2018-11-26)
Rapid cell migration requires efficient rear de-adhesion. It remains undetermined whether cells mechanically detach or biochemically disassemble integrin-mediated rear adhesion sites in highly motile cells such as keratocytes. Using molecular tension sensor, we calibrated and mapped integrin tension in migrating

Molecules (Basel, Switzerland), 24(12) (2019-06-23)
Stapled α-helical peptides represent an emerging superclass of macrocyclic molecules with drug-like properties, including high-affinity target binding, protease resistance, and membrane permeability. As a model system for probing the chemical space available for optimizing these properties, we focused on dual
