Furthermore, treating serum with 2-mercapthoethanol increases the specificity of the test by destroying IgM pentamers
that can interfere with evaluation of IgG but does not fully eliminate false positives because of heterologous cross-reactions (14, 27).
ARE basic motifs include pentamers
of AUUUA, nonamers of UUAUUUAUU, and AU-rich clusters composed of linked pentamers
Zeng POCl3-mediated H-bonding-directed one-pot synthesis of macrocyclic pentamers
, strained hexamers and highly strained heptamers, SCI China Chem, 55, 55 (2012).
Mammalian nAChRs contain five subunits divided into the alpha ([alpha]2-[alpha]7, [alpha]9, and [alpha]10) and beta ([beta]2-[beta]4) subfamilies, which assemble into both heteromeric and homomeric pentamers
It is still unclear if nAChR subunits of monocytic cells actually form conventional pentamers
as shown in the schematic drawing.
The used rMBL preparation consists largely of pentamers
, hexamers, and heptamers of such subunits and has thus 15-21 AF680 fluorophores per rMBL molecule.
The mature human immunodeficiency virus-1 (HIV-1) capsid is best described by a fullerene cone model, in which hexamers of the capsid protein are linked to form a hexagonal surface lattice that is closed by incorporating 12 capsid-protein pentamers
. HIV-1 capsid protein contains an amino-terminal domain (NTD) comprising seven (3-helices and a (3-hairpin, a carboxy-terminal domain (CTD) comprising four a-helices, and a flexible linker with a 310-helix connecting the two structural domains.
(72) One important feature of galectin-3 is its ability to form small clusters of galectin-3 molecules bound together in pentamers
. This allows the molecule to participate in multiple cellular and extracellular processes involving tissue growth, structure, and immune modulation.
IgM antibodies, being pentamers
, are efficient agglutinins; with five antigen-binding sites, they can bridge this distance.
Procyanidin trimers to pentamers
fractionated from apple inhibit melanogenesis in B16 mouse melanoma cells.
As a result, plasma cells secrete IgM either as "hexamers" [([H.sub.2][L.sub.2]).sub.6] or as "pentamers
" [([H.sub.2][L.sub.2]).sub.5]J, in which a third antibody component, the J-chain, joins the "monomeric" units, again by disulfide bonds .
The recombinant PPV VP2-derived VLPs were found to be stable when lyophilized and stored at -20[degrees]C longer than a year and VLPs remained intact when resolubilized in PBS as no pentamers
or disrupted particles were observed by electron microscopy (Figure 2(b)).
