Shelf life study addressing room temperature and ambient Light storage of MultiDots and MagDots

To assess shelf life stability we placed one of our reagents, the MagDot 655 conjugated to anti-human CD4 at room temperature under ambient lighting for two months.  

Cytocomp cells were labeled with the MagDot 655 weekly over the course of 2 months and analyzed on a BD LSR-II using a 405 nm excitation laser and Qdot 655 filter for capture.  As shown in the histograms on the right, the fluorescent properties of the MagDot remain stable.


Super stable reagents

Organic dyes and tandem dyes tend to photobleach and/or de-couple in ambient lighting over time.  MultiDots and MagDots do not lose their fluorescence intensity while storing and working in natural lighting.

What would greater reagent stability mean for your research?
