Binding afiinity

Albumin also binds thyroxine (RIO), but its binding afiinity is considerably less than is that of TBG, and therefore albumin plays less of a role in thyroxine transport. 

Titration of Qb in the mutant, however, suggested a role for quinone binding in this effect (Fig. 4a). Qb activity was assayed by the ability of the RCs to oxidize cytochrome C on a second flash. From figure 4a, the binding afiinity (x-intercepts) appears to change with pH (plotted in Fig. 4b), while the ET equilibrium (y-intercept) is unaffeaed. The pK for the binding affinity is approximately 7.8.

Similarly to the detection of afiinity events in immunosensors, the direct detection of the interactions between analyte and proteins generally requires highly sensitive techniques that may not offer the required robustness for routine analysis, in situ or on-site environmental practice. Surface plasmon resonance (SPR) is currently used for the real-time detection of a multitude of biological binding events. This technique has been applied to the detection of cadmium due to its interaction with the... 

The concentration and afiinity of somatomedin receptors on intact cells and isolated membranes are subject to modulation by a variety of ctors. In common with many other peptide hormone receptors, SM-C/IGF-I receptors on cultured IM-9 lymphocytes are down-regulated by exposure of the cells to SM-C/IGF-I. Insulin and other related peptides are also capable of causing receptor loss, with a potency proportional to their ability to bind to the SM-C/IGF-I receptor (RII). In contrast, binding sites for MSA tracer (i.e., type-II sites) on chondrosarcoma chondrocytes are reported to be un-...

Figure 1. The A and B X-ray dii action spatial (3-dimensional) configurations of the double hehx deoxyribose DNA molecule are fi om Rosalind Franklin s lab (1951). The A-DNA B-DNA photographs are from Baianu 1C et al. Maurice Wilkins lab yielded the C configuration in 1958. DNA A and B are natural (derive from living cells) DNA C configuration is an artifact formed in the drying process of a lithium-DNA salt. RNA the predecessor of DNA, is equipped with the 2 OH group on each of its ribose molecules it frequently functions single-stranded (ss), but in certain circumstances (ds RNA vimses) it can assume a double-stranded (ds) helical structure (A-RNA to Z-RNA). The interferon-induced enzyme dsRNA adenosine deaminase acting on RNA (ADAR) promotes the A-to-Z left-handed helical dsRNA transition ADAR specifically with high afiinity binds to ds Z-RNA/Z-DNA.
