This study describes a novel fabrication method of a multi-pad paper plate (MP) for transfer and optimisation of enzyme-linked immunosorbent assays (ELISA) on paper. The plate was fabricated using a combination of laser cutting and lamination for rapid and low-cost production of a multi-pad paper plate compatible with a standard 96 well microplate format. The plate was used to transfer a sandwi...

BACKGROUND The differentiation of floor plate cells and motor neurons in the vertebrate neural tube appears to be induced by signals from the notochord. The secreted protein encoded by the Sonic hedgehog (Shh) gene is expressed by axial midline cells and can induce floor plate cells in vivo and in vitro. Motor neurons can also be induced in vitro by cells that synthesize Sonic hedgehog protein ...

A high-throughput ultrafiltration method with a direct injection assay has been developed to determine unbound concentrations of a high-protein binding compound, an alpha(v)beta(3) bone integrin antagonist (I), in human plasma for a clinical pharmacokinetic study. The 96-well MultiScreen filter plate with Ultracel-PPB membrane was evaluated for the separation of unbound from protein-bound compo...

The measurement of intracellular calcium response transients in living mammalian cells is a popular functional assay for identification of agonists and antagonists to receptors or channels of pharmacological interest. In recent years, advances in fluorescence-based detection techniques and automation technologies have facilitated the adaptation of this assay to 384-well microplate format high-t...
