endocytosis

FM4-64 (SynaptoRedTM C2) is a stylane-based dye that is largely non-fluorescent in aqueous solution. FM4-64 cannot passively diffuse into the cell interior after binding to the plasma membrane bilayer and must be transported across the membrane by active transport. FM4-64 can be used to study endocytosis exocytosis and vesicle trafficking.

Lucifer Yellow CH dipotassium is a water-soluble fluorescent tracer that labels endocytosis vesicles in cells.Lucifer Yellow CH dipotassium excites and emits at a maximum wavelength of 430 nm and 540 nm, respectively.

4-Di-1-ASP is a positively charged fluorescent dye used to label glioma cells in live brain tissue and can also be used to observe mitochondria in live cells, with λex λem = 475 606 nm.

HB-2-30 is a far-red fluorescent transglutaminase 2 (TG2) probe for in vitro and in vivo endocytosis imaging. HB-2-30 complexes with TG2 and α2-macroglobulin for efficient endocytosis via the LRP1 pathway.

Arg-Flipper 34, a flipper probe fluorophore, is used to image membrane tension in living systems and assess the mechanics of early endocytosis [1].

PM-1, a Thioflavin-T (ThT) derivative, is a small, highly specific fluorescent dye for plasma membrane (PM) imaging in living and fixed cells. It integrates directly into the cell membrane and retains its presence on the PM for about 15 hours. PM-1 can be combined with protein labeling probes to investigate ectodomain shedding and endocytosis of cell surface proteins [1].
