โฆ Synopsis
Mammalian P-glycoprotein is a highly conserved 170-kD integral plasma membrane protein functioning as an energy-dependent efflux pump of exogenous and endogenous lipophilic aromatic compounds entering the cell by diffusion. In this study, the tissue specificities of one polyclonal (pAb) and three monoclonal (mAbs) antibodies t o mammalian P-glycoprotein were identified in paraffin-embedded, parasagittal whole-body sections of the guppy Poecilia reticulata. Polyclonal antibody mdr(Ab-1) and mAbs C219, C494, and JSB-1 demonstrated differential staining patterns in the following tissues: bile canaliculi in the liver, exocrine pancreas, lumenal surface of the intestinal epithelium, renal tubules, interrenal tissue, branchial blood vessels, gas gland, pseudobranch, and the gill transverse septa.

Immuno-enzymatic assay employing monoclonal antibodies and viral RNA analysis by gel electrophoresis were used to classify human group A rotaviruses (HRV) into subgroups I and II. Of 249 fecal samples positive for group A rotaviruses, 29 (11%) belonged to subgroup I and 215 (85%) were identified as
The survival of human proteins in blood stains on fragments of cloth buried in exposed soil was examined in a 15-month investigation carried out from September 1990 to December 1991. During this period there was a wide variety of weather conditions. Samples were exhumed at 4-weekly intervals for 16
