E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... 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
