Notch1 Phase Separation Coupled Percolation facilitates target gene expression and enhancer looping.

The Notch receptor is a pleiotropic signaling protein that translates intercellular ligand interactions into changes in gene expression via the nuclear localization of the Notch intracellular Domain (NICD). Using a combination of immunohistochemistry, RNA in situ, Optogenetics and super-resolution live imaging of transcription in human cells, we show that the N1ICD can form condensates that positively facilitate Notch target gene expression. We determined that N1ICD undergoes Phase Separation Coupled Percolation (PSCP) into transcriptional condensates, which recruit, enrich, and encapsulate a broad set of core transcriptional proteins.

PlayBack cloning: simple, reversible, cost-effective cloning for the combinatorial assembly of complex expression constructs.

With advancements in multicomponent molecular biological tools, the need for versatile, rapid and cost-effective cloning that enables successful combinatorial assembly of DNA plasmids of interest is becoming increasingly important. Unfortunately, current cloning platforms fall short regarding affordability, ease of combinatorial assembly and, above all, the ability to iteratively remove individual cassettes at will. Herein we construct, implement and make available a broad set of cloning vectors, called PlayBack vectors, that allow for the expression of several different constructs simultaneously under separate promoters.

Effects of Lithium Metal Storage Environment on Its Reactivity toward Polyethylene Oxide-Based Blend Electrolytes.

Lithium metal has generated significant interest as an anode material because of its high theoretical capacity. However, issues such as dendrite growth and lithium loss during cycling make this material incompatible with liquid electrolytes. Solid polymer electrolytes (SPE) have been proposed as replacements as they are non-flammable, resist dendrite growth, have decent ionic conductivity, and have low resistance with lithium metal.
