A variety of gram-positive and gram-negative intact bacterial cells have been analysed by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and shown to provide fingerprint mass spectra with discrete peaks being observed over the mass range from 3 to 40 kDa.

Shell cross-linked nanoparticles (SCKs) presenting surface- and bioavailable biotin functional groups were synthesized via a mixed micelle methodology, whereby co-micellization of chain terminal biotinylated poly(acrylic acid)-b-poly(methyl acrylate) (PAA-b-PMA) and nonbiotinylated PAA-b-PMA were cross-linked in an intramicellar fashion within the shell

Chicken avidin is a key component used in a wide variety of biotechnological applications. Here we present a circularly permuted avidin (cpAvd4-->3) that lacks the loop between beta-strands 3 and 4. Importantly, the deletion of the loop has a positive

The chicken genome encodes several biotin-binding proteins, including avidin and avidin-related protein 4 (AVR4). In addition to D-biotin, avidin binds an azo dye compound, 4-hydroxyazobenzene-2-carboxylic acid (HABA), but the HABA-binding properties of AVR4 are not yet known. Differential scanning calorimetry
