Lobsters, like most crustacean arthropods, have hemocyanin that is composed predominately of hexamer and dodecamer aggregates, with small concentrations of 24-mers and 48-mers (Mangum et al.
including an analytical method for quality profiling of hemocyanin oligomers and a scaled-up semipreparative HPLC method for extracting hemocyanin hexamer and dodecamer oligomers from lobster hemolymph.
Dodecamer and hexamer fractions were collected several times and reanalyzed using the analytical HPLC method.
Evidence that a dodecamer duplication in the gene HOPA in Xq13 is not associated with mental retardation.
For example, a famous sequence called the Dickerson-Drew dodecamer (5'-CGCGAATTCGCG) (2) can bind another copy of itself by classic Watson-Crick base pairing (A-T and G-C pairs, figure 1a).
According to previous studies, ASAs are produced against fertilization antigen (FA-1) and dodecamer peptide sequence (YLPVGGLRRIGG designated as YLP12) are important in infertility (7).
His team say that two of these "six-mer" rings stack to form a dodecamer, or "twelve-mer", and then the aggregation stops.
These dodecamer clusters are long-lived, but may eventually rearrange to form so-called B-sheet structures, which lead to the large fibrils that form the plaques found in the brains of those with Alzheimer's disease and other neurodegenerative diseases.
Synthesis of octa- and dodecamers of Dribitol-1-phosphate and their protein conjugates.
thermydron was comprised of a mixture of monomers, hexamers, dodecamers, and octodecamers; and these results were later confirmed using electrospray ionization mass spectrometry (ESI-MS) (Zal et al.
