Near-infrared (NIR) imaging is a promising technique for use as a noninvasive and sensitive diagnostic tool. Although the NIR fluorescently labeled glucose analog glucosamine (cypate-glucosamine) has applications in preclinical imaging, the transport pathways and fate of this probe in tissues
Analogs of cGMP bearing diverse substituents at the C8 position of the guanine ring system have been shown to activate the cGMP-activated channel of retinal rods at concentrations lower than cGMP itself. In an effort to understand this behavior, we
Oxidoreductases, such as glucose oxidase, can be electrically "wired" to electrodes by electrostatic complexing or by covalent binding of redox polymers so that the electrons flow from the enzyme, through the polymer, to the electrode. We describe two materials for
Horse liver alcohol dehydrogenase is inactivated with Michaelis kinetics at pH 7 and 25 degrees C by 3-bromopropionic acid. In the absence of NAD+, the Ki is 2 mM, and the pseudo bimolecular rate constant (k3/Ki) is 0.03 M-1 s-1;
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
