Thermal denaturation of four oligonucleotides, viz. 3'-d(AT)5pO(CH2)6Opd(AT)5-3'(par(AT], 3'-d(AT)5pO(CH2)6Opd(AT)5-5'(anti(AT],3'-d(A)10pO(CH2) 6Op(T)10-3'(par(A-T], and 3'-d(A)10pO(CH2)6Opd(T)10-5' (anti(A-T], was studied in 0.01 M phosphate buffer

[Intramolecular G-quadruplexes from microsatellite d(GT)12 sequence in the presence of K+]

Autor: D N, Kaliuzhnyĭ, F S, Bondarev, A K, Shchelkina, M A, Livshits, O F, Borisova

Publikováno v: Molekuliarnaia biologiia. 42(4)

Polymorphic d(GT)n microsatellite sequences are known to drastically affect genes expression. By use of CD spectroscopy, UV melting, fluorescence polarization of EtBr probe and FRET, we detected formation of a new fold with three G-quartets by d(GT)1

[Parallel-stranded DNA with natural base sequences]

Autor: A K, Shchelkina, O F, Borisova, M A, Livshits, T M, Jovin

Publikováno v: Molekuliarnaia biologiia. 37(2)

Noncanonical parallel-stranded DNA double helices (ps-DNA) comprising natural nucleotide sequences are usually second in stability to antiparallel-stranded (aps) canonical DNA structures, which ensures reliable cell functioning. However, recent data

Publikováno v: Biofizika. 47(2)

The amino-reactive derivative of tetraphenylporphine meso-tetrakis[4-(carboxy)phenyl]porphine (TCPP) was synthesized, which is characterized by a high molar absorption coefficient (epsilon 416 = 36,500 M-1.cm-1). TCPP was covalently attached to oligo
