Gruenwedel D, Hsu C
Biopolymers . 2012 Mar; 7(4):557-70. PMID: 22442846
When DNA's of differing GC:AT base ratios, e.g. synthetic poly dAT, T4 DNA,calf thymus DNA, E. coli DNA, and M. lysodeikticus DNA, are heat-denatured at neutral pH in increasing concentrations...

J Inorg Biochem . 1994 Nov; 56(3):201-12. PMID: 7798901
The addition of Hg(ClO4)2(Hg(II)) to 2'-deoxyadenosine (dA), thymidine (dT), to their respective 5'-monophosphates (dAp,dTp) as well as to the dinucleoside phosphates 2'-deoxyadenylyl-(3'-->5')-2'-deoxyadenosine (d(ApA)), 2-deoxyadenylyl-(3'-->5')thymidine(d(ApT)), thymidylyl-(3'-->5')-2'-deoxyadenosine (d(TpA)), and thymidylyl-(3'-->5')thymidine (d(TpT))--all dissolved...

Gruenwedel D
Biophys Chem . 1994 Oct; 52(2):115-23. PMID: 7948714
Adding, respectively, increasing amounts of Hg(ClO4)2 (identical to Hg(II)) to poly[d(A-T).d(A-T)] (I), poly[d(A).d(T)] (II) as well as to their constituent subunits 2'-deoxyadenosine (identical to dA), thymidine (identical to dT), 2'-deoxyadenosine-5'-...

Eur J Biochem . 1994 Jan; 219(1-2):491-6. PMID: 8307016
The B<==>Z transition of poly[d(G-m5C).d(G-m5C)] in buffered solution (0.002 M sodium cacodylate, pH 7) was studied by CD and ultraviolet spectroscopy as a function of the supporting electrolyte concentration (0.002-1.1...

Gruenwedel D, Cruikshank M, Smith G
J Inorg Biochem . 1993 Dec; 52(4):251-61. PMID: 8120531
Exposing the palindromic dodecamer d(GCGCATATGCGC)2, dissolved in the neutral-salt solvent 0.1 M (identical to low salt) or 3.0 M (identical to high salt) NaC1O4, to increasing amounts of Hg(C1O4)2 (identical...

Ok S, Gruenwedel D
Z Naturforsch C J Biosci . 1993 May; 48(5-6):488-94. PMID: 8395852
The long-wavelength positive CD bands of poly[d(A).d(T)] and poly[d(A-T).d(A-T)] become inverted upon the addition of Hg(ClO4)2. Poly[d(A).d(T)] requires higher levels of mercury to undergo inversion than poly[d(A-T).d(A-T)]. Mercurated poly[d(A).d(T)] is...

Gruenwedel D, Cruikshank M
J Inorg Biochem . 1991 Jul; 43(1):29-36. PMID: 1940900
The conformation of poly[d(T-G).d(C-A)] in aqueous solution (0.1 M NaClO4, 5 mM cacodylic acid buffer, pH 6.9) was studied by circular dichroism (CD) spectroscopy in the ultraviolet. The conformation of...

Lin I, Gruenwedel D
Food Addit Contam . 1990 May; 7(3):357-68. PMID: 1696215
N-Nitrosothiazolidine-4-carboxylic acid (NTCA) was prepared by treating L-thioproline with sodium nitrite at pH 2, 37 degrees C. The compound was characterized by mass spectrometry, infrared spectroscopy and 1H-nuclear magnetic resonance...

Biochemistry . 1990 Feb; 29(8):2110-6. PMID: 2328243
Exposing native calf thymus DNA to increasing concentrations of Hg(ClO4)2 not only produces dramatic changes in its circular dichroism (CD) but results also in the decrease, and ultimate cessation, of...

Gruenwedel D, Cruikshank M
Nucleic Acids Res . 1989 Nov; 17(22):9075-86. PMID: 2555784
Poly[d(A-T).d(A-T)] and poly[d(G-C).d(G-C)], each dissolved in 0.1 M NaClO4, 5 mM cacodylic acid buffer, pH 6.8, experience inversion of their circular dichroism (CD) spectrum subsequent to the addition of Hg(ClO4)2....
