Nuclear Black(TM) LCS1 *Cell-Permeable*

Nuclear Black(TM) LCS1 is a novel cell permeable, fluorescence suppression reagent designed to reduce green nuclear background from live cells in fluorescence imaging experiments. Some commonly used cellular stains may cause excessive or non-specific nuclear fluorescence in live-cell assays. Nuclear Black(TM) LCS1 permeates intact cells and suppresses undesired green nuclear signals, improving overall image contrast and clarity. Nuclear Black(TM) LCS1 is ideal for live-cell fluorescence microscopy, high-content screening, and imaging workflows where high background from nuclear staining in live cells interferes with signal interpretation. Its cell-permeable formulation integrates seamlessly into existing protocols to enhance green fluorescence visualization without affecting the target readout.
