Nucleolin aptamer (AS1411) (ID# 290)

Nucleolin aptamer (AS1411)
* The secondary structure may not be accurate because of MFOLD limitations on chemistries other than RNA/DNA.
DNA Nucleolin Protein N/A nM (reported value) For fluoresecent labeling, 400 nM aptamer were added to cell growth media for 1 hour at 37°C and 5% CO2. Dulbecco's phosphate-buffered saline was used to wash cells. N/A If the oligo is a known aptamer sequence: For binding studies, perform a refolding program to ensure proper function (i.e. binding to antigen or target). Refer to the aptamer reference source for the appropriate refolding parameters and binding conditions. Note: it is unknown whether aptamer functions properly without refolding. The image does not reflect the G quartet structure.

Kotula's et al. research suggests that the aptamer is internalized through a nonstandard mechanism.
