Popis: |
sIgA possessing ability to hydrolyse plasmid DNA to linear forms was purified from human milk by sequential chromatography on protein A-sepharose, DEAE-Fractogel and DNA-cellulose. It was discovered that incubation of sIgA with nuclei of porcine embryo kidney cells permeabilized by Triton X-100 causes formation of electrophoretically mobile forms of nuclear nucleic acids and inhibition of phosphorylation of nuclear proteins. We suppose that sIgA possessing affinity to DNA and endonuclease activity can cause degradation of cell nuclear chromatin. |
