Description

Application

Chromogenic reagent for antimony in the low ppm range and for gallium and indium in the sub-ppm range.

Biochem/physiol Actions

Potent inhibitor of osteoclastic bone resorption. The effect is believed to be attributable to both the antioxidant and estrogenic activities of kaempferol.

A flavonol shown to revert the transformed phenotype of phorbol ester-treated mouse fibroblasts or v-H-ras-transformed NIH 3T3 cells. Induces significant nuclear DNA degradation concurrent with lipid peroxidation. Inhibits topoisomerase I catalyzed DNA religation. Kaempferol may also inhibit the activity of fatty acid synthase.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
