The presence and location of specific binding sites for progesterone and 17β-estradiol in cells of wheat were estimated using radioligand binding assay. Membrane and cytosolic fractions of non-vernalized and vernalized plants were tested using tritium-labelled ligands. Specific binding of [3H]progesterone and [3H]17β-estradiol occurs in wheat cells. The binding sites are located in membranes and in...
Exposure of Rhizopogon roseolus mycelia to 15 mmol·dm⁻³ cadmium for 24 h induces a different pattern of Mn-SOD on polyacrylamide gels, probably being a changed form of an originally existing one. The presence of cadmium affects the chromatographic properties of this enzyme and its mobility through the acrylamide gel. This new isoform was purified using DEAE Trisacryl chromatography. Cadmium induced...
