C-Reactive Protein (ID# 7819)

Aptamer Chemistry: RNA

Target: C-Reactive Protein (CRP)

Antigen/Target Category: Protein

Affinity (Kd): 125 nM (reported value)

Binding Conditions/Buffer: SPR Binding Buffer: HEPES at pH 6.5 with 0.005% Tween 20

Binding Temp: 25°C

Refolding Protocol: NA 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.

Specificity: Binding is stabilized with the addition of CaCl₂ but the aptamer also produces signal in the absence of CaCl₂

Sequence ():

Length: 44

Molecular Weight: 14346.65

Extinction Coefficient: 444700

Note: Information on this aptamer oligo was obtained from the literature and hasn't been validated by Aptagen.
