Discussed here is the preparation, detailed purification, and evaluation of nitroavidin as a ligand for surface capture and release of biotinylated proteins. Avidin from chicken egg white was nitrated using dilute tetranitromethane solutions. UV-vis spectroscopy was used to show decreased binding of the biotin analogue, 2-(4'-hydroxyazobenzene)benzoic acid, HABA, to nitroavidin compared to binding of HABA to native avidin. From enzyme-linked immunosorbent assay (ELISA)-based assays of the…

Captavidin: a new regenerable biocomponent for biosensing?
TLDR
It is indicated thatCaptavidin is a promising regenerable molecular tool that could be used during biosensor optimisation and validation, and that captavidin-modified surfaces could be fine-tuned into truly reusable sensors.
Mass spectrometry and 3-nitrotyrosine: strategies, controversies, and our current perspective.
TLDR
It is shown that the application of sophisticated mass spectrometric techniques is advantageous if not essential, but that this alone is by no means a guarantee of accurate findings.
Imparting Immunomodulatory Activity to Scaffolds via Biotin-Avidin Interactions.
TLDR
It is demonstrated that the degree of scaffold biotinylation controlled the binding of two different avidin variants, streptavidin and CaptAvidin, to deliver the immunomodulatory cytokine, interleukin 4, from a porous gelatin scaffold, Gelfoam, to primary human macrophages in vitro.
Grading the commercial optical biosensor literature—Class of 2008: ‘The Mighty Binders’
TLDR
This work grades every paper published in 2008 on a scale from A to F and outlines what features make a biosensor article fabulous, middling or abysmal and focuses on a few experimental, analysis and presentation mistakes that are alarmingly common.
