A cell sorter with modified bamboo charcoal for the efficient selection of specific antibody-producing hybridomas.

Monoclonal antibodies (mAbs) have been proven useful in research and clinical applications. However, the generation of mAbs by conventional hybridoma technology is time-, cost- and labor-consuming. Here we developed a simplified procedure for efficient generation and selection of antibody-producing hybridomas within 1 h, using a particular cell sorter design, a cytoflow reactor-based cell sorter (CBCS) which consists mainly of the "cytoflow reactor" that comprises two components, a reaction chamber and a glass tubing for air and medium exchange by gravity, and the "sorting material", human EGFR-conjugated bamboo charcoal, for specific B-cell enrichment.

A new fish scale-derived scaffold for corneal regeneration.

The purpose of this study is to develop a novel scaffold, derived from fish scales, as an alternative functional material with sufficient mechanical strength for corneal regenerative applications. Fish scales, which are usually considered as marine wastes, were acellularized, decalcified and fabricated into collagen scaffolds. The microstructure of the acellularized scaffold was imaged by scanning electron microscopy (SEM).

GSK-3 mediates the okadaic acid-induced modification of collapsin response mediator protein-2 in human SK-N-SH neuroblastoma cells.

Collapsin response mediator protein-2 (CRMP-2), a phosphoprotein involved in axonal outgrowth and microtubule dynamics, is aberrantly phosphorylated in Alzheimer's disease (AD) brain. Alteration of glycogen synthase kinase-3 (GSK-3) activity is associated with the pathogenesis of AD. Here, we show that CRMP-2 is one of the major substrates for GSK-3 in pig brain extracts.
