In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More
Sulfonated and non-sulfonated cyanines exhibit very similar fluorescent properties. Non-sulfonated cyanines must be dissolved in organic co-solvent (DMF or DMSO) prior to use, and added to a solution of target molecule in aqueous buffers. Recommended volume of co-solvent should be 10% for Cy3, C... Read More
