CD4 (aptamer 12) (ID# 369)

CD4 (aptamer 12)
* The secondary structure may not be accurate because of MFOLD limitations on chemistries other than RNA/DNA.
2'-F-RNA CD4 protein found on CD4+ T-Cells Protein 0.5 nM (reported value) Binding Buffer: PBS containing 1 mM MgCl2 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. This aptamer was also used for cell capture. (Q Zhou et al. "Aptamer-containing surfaces for selective capture of CD4 expressing cells." Langmuir 28(2012):12544-12549.)
