Two known site-selective markers for BSA, bilirubin (BR, for site I) and diazepam (DIA, for site II), were selected to bind to the two potential binding sites of BSA (site I and site II).
Thus, TRAPs with novel binding specificity can be generated by mixing-and-matching TRAP pockets that have been selected to bind particular amino acids rather than performing new selections for every peptide target.
In DARPins that have been selected to bind to a designated target, the residues that do not form the binding site are conserved, whereas the residues that form the binding site are derived from randomised sequences.
DARPins are small, single domain proteins (14 kDa) which can be selected to bind any given target protein with high affinity and specificity.
Peptides and proteins have also been selected to bind metals, semiconductors and ions, inspiring the design of new materials for a wide range of applications in nano-biotechnology.
In this study we have used peptide motifs that have been selected to bind to gold, platinum, glass and titanium to modify surfaces with poly ethylene glycol) anti-fouling polymer and the integrin-binding RGD sequence.
There is little conservation of the wild-type amino acid residues at the five randomized positions in the variants that were selected to bind to the wild-type site, yet one of the purified derivatives displays DNA-binding specificity and DNA endonuclease activity that is similar to that of the wild-type enzyme.
Here, we have shown that RNA aptamers can be selected to bind the Nogo-66 receptor (NgR) and compete with myelin-derived inhibitors of axon regeneration for binding to the receptor.
Based on preclinical studies showing enhanced efficacy of mAbs that bind to Aβ, the vast majority of mAbs that have advanced to trials have been selected to bind both monomeric and aggregated forms of Aβ.
This event is selected to bound possible damage to the systems in the cryostat.
