Microtiter-Format Assays for HBV Antigen Quantitation in Nonclinical Applications.

Measurement of secreted HBV antigens in cell culture is an important endpoint in many experimental settings. Here we describe convenient and inexpensive protocols for 96-well format sandwich ELISA assays for this purpose, in which there are many options for customization of antibodies used and other parameters. These protocols can be adapted to use for animal serum samples, compound library screening, and other purposes.

Oxidant-mediated mitochondrial injury in eosinophil apoptosis: enhancement by glucocorticoids and inhibition by granulocyte-macrophage colony-stimulating factor.

The mainstay of asthma therapy, glucocorticosteroids (GCs) have among their therapeutic effects the inhibition of inflammatory cytokine production and induction of eosinophil apoptosis. In the absence of prosurvival cytokines (e.g.
