pH: 8 詳細: the RecA5 fusion protein was incubated with a 1.5-fold molar excess of the primary d(T5C3AC2T4) oligonucleotide in protein buffer supplemented with 2 mM ADP, 10 mM MgCl2 and 8 mM AlF4, pH 6. ...詳細: the RecA5 fusion protein was incubated with a 1.5-fold molar excess of the primary d(T5C3AC2T4) oligonucleotide in protein buffer supplemented with 2 mM ADP, 10 mM MgCl2 and 8 mM AlF4, pH 6.0, for 30 min, followed by the addition of 2-fold molar excess of the complementary d(G2TG3) oligonucleotide. The crystals grew from 50 mM Tris-Cl, 9% (w/v) PVP K15, 32% (v/v) MPD, 100 mM magnesium acetate, 10 mM DTT, pH 8.0.
