Inhibitory activity of bivalent peptide DV1-K-(DV3) in blocking calcium influx triggered by SDF-1α. The influx of Ca2+ from endoplasmic reticulum into cytoplasm was measured in response to treatment with SDF-1α and the peptide. The SUP-T1 cells were pre-incubated with various concentrations of the peptide for 2~3 min, followed by addition of 50 nM SDF-1α to stimulate the Ca2+ influx.
