Fluorescent conjugates of LPS will help researchers to follow LPS binding and transport processes. Cell internalization studies can utilize trypan blue to quench the fluorescence of surface bound LPS.7 In one study a BODIPY ® FL derivative of LPS from E. coli strain LCD25 was used to measure the transfer rate of LPS

In this study, we have devised a new methodology for labeling LPS, using hydrazide and galactose oxidase in order to oxidize galactose residues to aldehyde groups in the oligosaccharide core of the LPS. We have managed to generate a conjugate that is highly fluorescent (LPS-to-Alexa 488 labeling ratio of 1:5) and biologically active.

Fluorescent conjugates of LPS will help researchers to follow LPS binding and transport processes, cell internalization studies. Store at 4℃ or lower. Protect from light. Solutions of 1–10 mg/mL can be made by dissolving the powder in the appropriate amount of …
