John Bowlby (1969/1982) opens the first book of his classic Attachment trilogy with this quotation from Sigmund Freud in a chapter titled “Point of View.” Bowlby then goes on to carefully outline his own paradigm-altering point of view, building from extensive observations of young children separated from their parents. Bowlby’s selection of this quotation suggests his recognition that viewing ...

Label-free detection of the interaction between hexahistidine-tagged human κ-opioid receptor membrane protein and anti-His antibody is demonstrated in liquid by an optical microelectromechanical system utilizing electromagnetically actuated microresonators. Shift in resonance frequency due to accretion of mass on the sensitive surface of microresonators is monitored via an integrated optical re...

We evaluate the ability of hexahistidine (His6) tags on peptide and protein substrates to recruit deoxyribozymes for modifying those substrates. For two different deoxyribozymes, one that creates tyrosine-RNA nucleopeptides and another that phosphorylates tyrosine side chains, we find substantial improvements in yield, kobs, and Km for peptide substrates due to recruiting by His6/Cu(2+). Howeve...
