SiR700-lysosome is based on the pepstatin A (a cathepsin D binding peptide) which has been labeled with the proprietary far-red fluorophore called silicon rhodamine 700 (SiR700). SiR700-lysosome is fluorogenic, cell permeable and highly specific for lysosomes. It stains early and late endocytic vesicles and lysosomes in live cells without the need for genetic manipulation or overexpression. Its emission in the far red minimizes phototoxicity and sample autofluorescence. SiR700-lysosome is compatible in dual fluorescence studies with other SIR dye conjugates, GFP and/or mCherry fluorescent proteins. It can be imaged with standard Cy5 filter sets, or high resolution filters for dual staining. SiR700-lysosome can be used for widefield, confocal, SIM or STED imaging in living cells and tissue. Probe quantity allows 35 – 140 staining experiments*.
