Optical anisotropy of alcian blue-stained acid glycosaminoglycans
(Elsevier B.V., 2007-01-01)
Optical anisotropy as dispersion of birefringence (DB) (birefringence studied for light of different wavelengths) and linear dichroism (LD) (selective absorption of polarized Light) in stained substrates reflects their ...
Chemical and biological characterization of four new linear cationic α-helical peptides from the venoms of two solitary eumenine wasps
(2011-06-01)
Four novel peptides were isolated from the venoms of the solitary eumenine wasps Eumenes rubrofemoratus and Eumenes fraterculus. Their sequences were determined by MALDI-TOF/TOF (matrix assisted laser desorption/ionization ...

Conformational preferences induced by cyclization in orbitides: a vibrational CD study
(Royal Society of Chemistry (RSC), 2022-01-18)
Orbitides are bioactive head-to-tail natural cyclic peptides from plant species. Their bioactivity is intrinsically related to the main conformations adopted in solution, whose correct characterization represents an important ...
Immunosensor for diagnosis of Alzheimer disease using amyloid-beta 1-40 peptide and silk fibroin thin films
(Elsevier Science Bv, 2016)
Layer-by-Layer (LbL) films containing silk fibroin (SF) and the 40 aminoacid-long amyloid-beta peptide (A beta 1-40) were prepared with the purpose of developing a new prototype of an electrochemical immunosensor. The film ...
MAGNETOOPTICAL PROPERTIES OF F-2(+) CENTER IN KCL-SH-
(Akademie Verlag Gmbh, 1993-04-01)
The magnetic circular dichroism (MCD) of F2+ centers in KCl:SH- has been measured in absorption in the 1ssigma(g) --> 2p(y)pi(u) transitions at 493 and 509 nm, with fields up to 5 T and in the temperature range 1.5 K < T ...
Anoplin, a novel antimicrobial peptide from the venom of the solitary wasp Anoplius samariensis
(Elsevier B.V., 2001-11-26)
A novel antimicrobial peptide, anoplin, was purified from the venom of the solitary wasp Anoplius samariensis. The sequence was mostly analyzed by mass spectrometry, which was corroborated by solid-phase synthesis. Anoplin, ...
Gamma Ray Irradiation of the Vasoactive Peptide Bradykinin Reveals a Residue- and Position-Dependent Structural Modification
(Springer, 2010-06-01)
In this work the effect of radical species generated by gamma ray irradiation of aqueous solution upon structure of vasoactive peptide bradykinin (BK, RPPGFSPFR) was investigated. Increasing doses of 1-15 kGy Co-60 gamma ...
