Histone H4 N-terminal tail (4.33) (ID# 7721)

H4 N-terminal tail
1.3 nM (reported value)
Low-salt conditions: 100 mM NaCl, 5 mM MgCl2, and 10 mM HEPES (pH 7.5).
High-salt conditions: 500 mM NaCl, 10 mM MgCl2, and 10 mM HEPES (pH 7.5).
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.
Kd values for other histones (low-/high-salt concentrations): H3 (14/273 nM), H2 A (204/4050 nM), and H2 B (84/825 nM).
Affinities for H3, H2 A, and H2 B histones are also provided.

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