Alterations in the extracellular Ca(2+) or K(+) concentration had significant influences on the motility of B16F10 melanoma cells measured in the absence of exogenous integrins using a conventional Boyden chamber assay. At normal K(+) concentrations, motility increased slightly when the
To investigate the biological effects of terbium (Tb), male mice were intraperitoneally administered with TbCl3 at doses of 10, 50, or 250 mg Tb/kg. The Tb distribution in organs was determined after 18-20 h of injection by using a spectrofluorometer.

Lanthanide metals such as terbium have previously been shown to be useful for mapping metal-binding sites in RNA. Terbium binds to the same sites on RNA as magnesium, however, with a much higher affinity. Thus, low concentrations of terbium ions
Reverse fluorescence staining of proteins in polyacrylamide gels using terbium chloride.

Our present study provided new evidence for diterbium transferrin (Tb(2)Tf) as a potential multi-photon-excited microscopy probe. It indicated that the Tb(2)Tf complex can be transported into human leukemia K562 cells via a process mediated by transferrin (Tf) receptors as an
Rare earth elements are vital in everyday life worldwide: catalysts in cars, colors in screens, magnets in electronics. Essential for modern living.
