TOTO-3
Based on 1 Customer Validation
TOTO-3 is a cyanine nucleic acid intercalating fluorescent probe that binds to both RNA and DNA (Ex=642 nm, Em=660 nm). TOTO-3 cannot enter intact cells, but can penetrate cells with permeabilized plasma membranes, staining cytoplasmic RNA and nucleoli to distinguish intact cells from damaged ones. TOTO-3 is taken up by macrophages in an ultrasound-independent manner. TOTO-3 accumulates in tumor cells via ultrasound-mediated enhancement of plasma membrane permeability. TOTO-3 supports optical imaging for real-time assessment of plasma membrane integrity, nucleic acid detection, and monitoring of ultrasound-mediated intracellular delivery processes. TOTO-3 is applicable to studies related to rectal cancer.

Activité biologique
TOTO-3 is a cell-impermeable dye, as it only enters and stains mouse rectal carcinoma line CMT-93 cells[1].
TOTO-3 (1 μM; 5 min at 37°C) discriminates between intact and membrane-compromised human HaCaT keratinocyte cells and human M4Beu melanoma cells, enabling selective analysis of viable cells for Ursolic acid (HY-N0140)-induced mitochondrial transmembrane potential changes[2].
