Formaldehyde crosslinking has been widely used to study binding of specific proteins to DNA elements in intact cells. However, previous studies have not determined if this crosslinker preserves the bona fide pattern of DNA binding. Here we show that formaldehyde crosslinking of Drosophila embryos maps an interaction of the transcription factor Zeste to a known target element in the Ultrabithora...
PURPOSE To evaluate the efficacy of corneal collagen crosslinking for progressive keratoconus in paediatric patients. METHODS This prospective study included 25 eyes of 18 patients (aged 18 years or younger) who underwent collagen crosslinking performed using riboflavin and ultraviolet-A irradiation (370 nm, 3 mW/cm2, 30 min). RESULTS The mean patient age was 14.3±2.4 years (range 8-17) and...
1A microwave (MW)-assisted crosslinking process to prepare hydrogel-forming microneedle (MN) arrays was evaluated. Conventionally, such MN arrays are prepared using processes that includes a thermal crosslinking step. Polymeric MN arrays were prepared using poly(methyl vinyl ether-alt-maleic acid) crosslinked by reaction with poly(ethylene glycol) over 24 h at 80 °C. Polymeric MN arrays were pr...
Antibodies developed during HIV-1 infection lose efficacy as the viral spike mutates. We postulated that anti-HIV-1 antibodies primarily bind monovalently because HIV's low spike density impedes bivalent binding through inter-spike crosslinking, and the spike structure prohibits bivalent binding through intra-spike crosslinking. Monovalent binding reduces avidity and potency, thus expanding the...
