Tyrian purple sea salt in the dye vat and adding potash, he was able to successfully dye wool a deep purple colour. Recent research in organic electronics has shown that Tyrian purple is an ambipolar organic semiconductor. Transistors and circuits based on this material can be produced from sublimed thin-films of the dye. The good semiconducting properties of the dye originate from strong intermolecular hydrogen bonding that reinforces pi stacking necessary for transport. True Tyrian purple, like most high-chroma pigments, cannot be accurately rendered on a standard RGB computer monitor. Ancient reports are also not entirely consistent, but these swatches give a
LifeAct Dye LifeAct Dye LifeAct Dye is a dye composed of a 17 amino acid recombinant protein that stains filamentous actin (F-actin) structures of eukaryotic living or fixed cells. The dye is a registered trademark of ibidi GmbH. There are several types and combinations of the dye that can be utilized depending on the cell type, protocol, and purpose of the analysis. LifeAct-TagGFP2 being the most widely used dye compared to other LifeAct constructs is composed of the first 17 amino acid from the "Saccharomyces cerevisiae" Abp140, an actin-binding protein. The Abp140 is highly conserved among "Saccharomyces cerevisiae" and other closely related
