Vaspin binding aptamer (VBA) (ID# 7774)
DNA
Vaspin
Protein
303 nM (reported value)
Binding Buffer: 100 mM NaCl, 25 mM Tris-HCl, 2 mM MgCl2, 5 mM KCl, 1 mM CaCl2, and 0.02% Tween-20, pH 7.6.
RT°C
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.
No significant signal was observed from RBP4, Nampt, adiponectin, human serum albumin, human IgG, and fibrinogen.
Limit of detection using ELAAS assay was 39 ng/ml. See SJ Lee et al (2012) for more details.
