PSA aptamer (PSap4#5) (ID# 7714)

<100 nM (reported value)
10 mM Tris/HCl, 150 mM NaCl, 5 mM KCl, 5 mM MgCl2, 0.05% Tween 20, pH 7.4, r.t.
The DNA library was heated at 95 °C for 10 min and then gradually cooled to 25 °C over a period of 30 min in TBS buffer (10mM Tris/HCl, 150mM NaCl, 5mM KCl, 5mM MgCl2, pH 7.4).
Binding was not detectable during the course of internal investigation. Gel-Shift and Forte-Bio Octet methods to attempt to determine Kd did not generate results indicative of aptamer-target binding.

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