Runtime Calls are compiled using a level of indirection this indirection is used to dynamically bind a call against an interface to a specific implementation at runtime based on the receiving object this can be combined with dynamic linking (Java) or static linking (C++).

Micelles offer a variety of highly dynamic binding sites, which makes their description as a reaction medium an intricate affair. Whereas vesicular dynamics are slower than micellar dynamics, this by no means results in more straightforward descriptions of the... 

The technique of gel filtration is widely used in biochemical research. Chapter 3 described the theory and applications of gel filtration to the experimental procedures of desalting, separation and purification of biomolecules, and estimation of molecular weight of biomolecules. In this experiment, gel filtration procedures will be used to study the dynamic binding of small molecules by proteins. Many of the dynamic processes occurring in biological cells and organisms are the result of interactions between molecules. Often these interactions involve one or more smaller molecules binding to a macromolecule (usually a protein or nucleic acid).

FIGURE 17 Dynamic binding capacity (DBC) for human polyclonal IgG of a HCIC column as a function of the pH (A) and of the ionic strength (B) of the medium. Determinations were performed by frontal analysis and calculations done at 10% breakthrough. IgG concentration was I mg/mL of initial solution linear flow rate was 75 cm / hr. 

Prior to scale-up, different protein A resins should be screened. To achieve high production rate, defined as the amount of protein purified per unit time and per unit column volume, a resin must have a high dynamic binding capacity and be able to operate at low backpressures.

Monolithic disks seem to be very efficient columns for the separation of polynucleotides. They enabled not only the separation of pDNA from RNA, but also the separation of pDNA isoforms supercoiled, open circular, and linear forms.Besides a separation time of only a few minutes, the most outstanding characteristic of the monolithic disks is their high dynamic binding capacity for pDNA, which is in the range of 10 mg/niL of support.

This question comes down to finding the change in the charge on the histidine. When the pK rises, the charge increases and the amount of the increase corresponds to the number of protons taken up. (Actually, the answer will be a fraction of a proton. This really means that the histidine, which is dynamically binding and releasing its proton, will be spending more time with the proton bound.)... 

We, therefore, developed a new method for enhancing albumin adsorption, a method that may provide indefinite protection against thrombogenesis and cell adhesion. The method takes advantage of the hydrophobic affinity and reversible dynamic binding of albumin from plasma to C18 alkyl residues that are, in turn, covalently bound onto various polymer surfaces.
