产品简介

SiR-DNA is a far-red, fluorogenic, cell permeable and highly specific live cell DNA probe for fluorescence imaging of the nucleus and DNA.Kit contains 50 nmol SiR-DNA and 1 umol verapamil

SiR-DNA is a live cell nuclear stain based on the DNA minor groove binder bisbenzimide, it allows the labelling of DNA in live cells with high specificity and low background. SiR-DNA is fluorogenic, cell permeable and highly specific for DNA. Sir-DNA stains the nuclei of live cells without the need for genetic manipulation or overexpression. Its emission in the far red minimizes phototoxicity and sample autofluorescence. SiR-DNA is compatible with GFP and/or m-cherry fluorescent proteins. SiR-DNA is a non cytotoxic alternative to DRAQ5. It can be imaged with standard Cy5 filtersets. SiR-DNA can be used for widefield, confocal, SIM or STED imaging in living cells and tissue. Probe quantity allows 50 – 200 staining experiments.*

*Based on the following conditions: 0.5 – 1 ml staining solution / staining experiments with 0.5 – 1 uM probe concentration. The number of staining experiments can be further increased by reducing volume or probe concentration.
