High affinity fluorescently tagged aptamer for CD133 (AC133 epitope) (Kd values are 33.9 and 83.2 nM in Hep3B and HT29 cells respectively). Efficiently internalized upon binding to CD133. Exhibits superior penetration of tumorspheres compared with an antibody to the same target.
For optimal binding aptamers require refolding into their tertiary structure prior to use. Please refer to the accompanying protocol for information regarding refolding and aptamer use in unfixed cell imaging and flow cytometry.
Sold under license from the patent holder, Deakin University.
