An insight into the binding and inhibition of eye ζ-crystallin by the environmental toxin arsenic: implications in eye diseases.

Arsenic contamination is highly prevalent in food chain, soil and groundwater. Continuous exposure to elevated levels of this environmental toxin is a global concern. Studies have reported enriched accumulation of arsenic in the eyes compared to other body organs leading to various eye diseases.

Immobilization of laccase on Sepharose-linked antibody support for decolourization of phenol red.

Laccases which are considered as "green tools" in biotechnology have potential to degrade toxic contaminants/synthetic dyes present in industrial effluents. The loss in activity and stability of laccases are key challenges faced in their potential industrial applications. Here, laccase from Trametes versicolor (polypore mushroom) was immobilized on Sepharose-linked antibody support to carry out the decolourization of phenol red.
