We present a generic approach for immobilizing oligohistidine-tagged proteins with high stability and homogeneous functionality onto glass-type surfaces. Multivalent chelator heads (MCH) carrying two and three nitrilotriacetic acid (NTA) moieties were coupled with controlled surface concentration to glass surfaces premodified with an ultrathin two-dimensional polymer brush of a bifunctional pol...
OBJECTIVE The aims of this study were to investigate whether fertilization could induce the resumption of meiosis in mouse oocytes arrested at metaphase I (MI) after in vitro maturation (IVM), and to investigate the effect of Ca2+ chelator treatment at the time of fertilization on the transition from MI to metaphase II (MII). METHODS MII-stage and arrested MI-stage mouse oocytes after IVM wer...
The interest in zirconium-89 (89Zr) as a positron-emitting radionuclide has grown considerably over the last decade due to its standardized production, long half-life of 78.2 h, favorable decay characteristics for positron emission tomography (PET) imaging and its successful use in a variety of clinical and preclinical applications. However, to be utilized effectively in PET applications it mus...
Nucleotide incorporation reactions, catalyzed by DNA and RNA polymerases, are critically important in the biological processes of living systems. Their common byproduct, pyrophosphate (PPi), is a negatively charged small molecule typically detected using optical techniques, such as chemiluminescence. Label-free electrical monitoring of biochemical reactions offers several advantages including i...
