Background: The Rh antigens are expressed as parts of a protein complex in the RBC membrane. This complex is a tetramer, consisting of two molecules of RhAG and two molecules of Rh proteins. To express RhD in RBC membrane, expression of RhAG is essential. This co-expression only occurs in the erythroid lineage. K562 cell line has an erythroid lineage. Materials and Methods: Cord blood was used ...

Bovine peripheral blood mononuclear cells (PBMC) were labelled with monoclonal antibodies recognizing bovine MHC class II, sIgM, monocyte, T-helper and T-cytotoxic cell phenotypes. They were sorted into positive and negative populations with a fluorescence-activated cell sorter (FACS). The cell populations were infected in vitro with sporozoites of either Theileria annulata or T. parva, and the...

Isolation of low abundance proteins or rare cells from complex mixtures, such as blood, is required for many diagnostic, therapeutic and research applications. Current affinity-based protein or cell separation methods use binary 'bind-elute' separations and are inefficient when applied to the isolation of multiple low-abundance proteins or cell types. We present a method for rapid and multiplex...

Scavenger receptors (ScRs) are a structurally unrelated family of receptors with the ability to bind modified low density lipoprotein (LDL) as well as a broad range of polyanionic ligands. CD68, whose expression is restricted to mononuclear phagocytes, is a unique ScR family member, owing to its lysosome associated membrane protein (LAMP)-like domain and predominant endosomal distribution. Knoc...

Actinide single-molecule magnetism has experienced steady growth over the last five years since the first discovery of slow magnetic relaxation in the mononuclear complex U(Ph(2)BPz(2))(3). Given their large spin-orbit coupling and the radial extension of the 5f orbitals, the actinides are well-suited for the design of both mononuclear and exchange-coupled molecules, and indeed at least one new...

In the title mononuclear complex, [Ag(C(10)H(6)N(4))(2)]BF(4), the Ag(I) atom adopts a square-planar N(4 )coordination geometry and is surrounded by two 5-(2-pyrid-yl)pyrazine-2-carbonitrile ligands. The tetra-fluorido-borate anions link the mononuclear cations through inter-molecular C-H⋯F hydrogen-bonding inter-actions, forming an infinite tape structure along [110]. Other weak inter-actions ...

Complex assembly preferences and resultant spin state choice Jahn-Teller distortion mode in twelve Mn(III) complexes of varying nuclearity with Schiff base chelate ligands different sizes are compared. Mononuclear Mn(5-F-Sal2323)]OTf (1), [Mn(5-F-Sal2323)]ClO4 (2) [Mn(5-F-Sal2323)]NO3, (3) the 8-carbon R-Sal2323 type show rare axial compression at room temperature also reversible thermal switch...

The title mononuclear Zn(II) complex, [ZnCl(2)(C(15)H(13)N(5))(2)], is isotypic with the previously reported Hg(II) complex. The Zn(II) atom is located on a twofold rotation axis and has a distorted tetra-hedral environment of two Cl atoms and two N atoms from two heterocyclic ligands. In the crystal, complex mol-ecules are extended by inter-molecular π-π inter-actions [centroid-centroid distan...

In the mononuclear title complex, [Ag(NO(3))(C(10)H(6)N(4))(2)], two κ(2)N:N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming an N(4)O square-pyramidal coordination geometry with one nitrate anion bonding at the apical site. The two heterocyclic rings of the 5-(2-pyridin-2--yl)pyrazine-2-carbonitrile ligand are almost coplanar [dihedral angle = 5.63 (8...
