Next, the scientists studied the molecular binding
between curcumin and sodium caseinate at pH 12, using fluorescence spectroscopy, which, based on the analysis using the Stern-Volmer equation, suggested a complex formation had occurred between the two molecules.
By shooting a laser through a sample and measuring how the light scatters after passing through it, MSI can determine molecular binding
between a new drug candidate and the target molecule.
It's one thing to observe molecular binding
in a test tube," said Cairo.
The electrochemical flow-through surface plasmon resonance (SPR) instrument analyzes molecular binding
processes and conformational changes of biomolecules under the influence of applied electrochemical potential and controlled flow.
Though produced from real sugar and exhibiting a very natural taste profile, isomaltulose is distinguished by a very strong molecular binding
, which cannot be broken by plaque bacteria and prevents the generation of acids that harm tooth enamel.
Absorbance ratios at 280 and 403 run indicated a 1:1 molecular binding
ratio of HRP to K267 Fab'.
With the ability to analyze and sort cells or particles at the rate of 50,000 per second, the modern flow cytometer is a valuable tool in many fields, not the least of which is biotechnology, a discipline that makes good use of the cytometer's capabilities in time-dependent subsecond analysis of cell response kinetics and molecular binding
Without the use of fluorescent markers, this system offers users the ability to simultaneously detect and map recognition or molecular binding
events with single molecule sensitivity, while generating topographic images--all in real-time.
This approach greatly enhances the rate and specificity of the molecular biological reaction, as evidenced by the Nanogen microarray's ability to accelerate molecular binding
up to 1,000 times faster than traditional passive methods.
The investigators are now racing to identify cGMP's receptor, a molecular binding
site that they presume resides somewhere on the surfaces of intestinal cells.
Polarization fluorescence, or when a molecule is excited by polarized light, is used to examine molecular binding
Patterned molecular binding
on surfaces as a route to nanostructured surfaces
