Human Immunoglobulin G (IgG) (Apt 8) (ID# 44)
Human Immunoglobulin G (IgG) (Apt 8) * The secondary structure may not be accurate because of MFOLD limitations on chemistries other than RNA/DNA.
Aptamer Chemistry
Antigen/Target Category
Affinity (Kd)
75 nM (reported value)
Binding Conditions/Buffer
Binding Buffer (145mM NaCl, 5.4 mM KCl, 0.8mM MgCl, 1.8 mM CaCl, and 20 mM Tris-HCl (pH 7.6)) Modifications at the 5' and 3' end have been made by the authors for various testing.
Binding Temp
Refolding Protocol

If the oligo is a known aptamer sequence: For binding studies, perform a refolding protocol 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.

Specific for Human IgG, subclasses hIgG1 through hIgG4.
Does not bind to mouse, rat, rabbit, bovine, chicken, canine, feline, and guinea pig IgG.
This aptamer binds to the Fc domain of hIgG.
