A23.2 (ID# 7914)

Aptamer Chemistry: DNA

Target: Staphylococcus aureus enterotoxin A (SEA)

Antigen/Target Category: Protein

Affinity (Kd): 235 nM (reported value)

Binding Conditions/Buffer: 20 mM Tris, 100 mM NaCl, 5 mM KCl, 1 mM CaCl2 and 1 mM MgCl2 ƒ?› 6H2O, pH 7.4

Binding Temp: 37°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.

Comments: ssDNA aptamers specific for SEA were selected using a 12-round SELEX procedure
