Tyrian purple Tyrian purple Tyrian purple (, "porphúra"; ), also known as Tyrian red, Phoenician purple, royal purple, imperial purple or imperial dye, is a reddish-purple natural dye. It is a secretion produced by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name "Murex". In ancient times, extracting this dye involved tens of thousands of snails and substantial labor, and as a result, the dye was highly valued. The main chemical is 6,6′-dibromoindigo. Tyrian purple may first have been used by the ancient Phoenicians as early as 1570 BC. The dye was greatly prized
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
