Structure and magnetic properties of a novel heteroheptanuclear metal string complex [NiRuNi(μ-teptra)(NCS)](PF).

We report the synthesis of a novel heteroheptanuclear metal string complex (HMSC) [NiRuNi(μ-teptra)(NCS)](PF) 1 supported by tetra-pyridyl-tri-amine (Hteptra) ligands. We employed X-ray diffraction and other spectroscopic techniques to characterize the complex. The observed remarkably short Ru-Ru distance of 2.

[Expression and immunological activity of an anti-CD3×VEGFR2 bispecific single-chain antibody].

Aim: To construct and express an anti-VEGFR2/anti-CD3 bispecific single-chain antibody (bscVEGFR2×CD3)and to identify its binding specificities to CD3 and VEGFR2.

Methods: The gene encoding anti-VEGFR2/anti-CD3 bispecific single-chain antibody was designed and synthesized. Bispecific single-chain antibody (bsc-Ab) DNA was subcloned into a eukaryotic expression vector pcDNA3.
