General description
Extinction coefficient(493 nm): 5900 M -1cm-1;(287 nm): 55,700 M -1cm-1;
Membrane impermeable DNA intercalator. Has red fluorescence at 488 nm. Useful for flow cytometry for staining apoptotic cells and nuclei. Can be used to differentiate between apoptotic and necrotic cell death while stains only necrotic cells. Can be used together with common green fluorescent probes labeled with fluorescein isothiocyanate (FITC).
Membrane impermeable DNA intercalator. Has red fluorescence at 488 nm. Useful for staining apoptotic cells and nuclei by flow cytometry. Can be used to differentiate between apoptotic and necrotic cell death. Can be used together with common green fluorescent probes labeled with fluorescein isothiocyanate. Has the following spectral properties: extinction coefficient: 5,900 M-1cm-1 (493 nm); 55,700 M-1cm-1 (287 nm); 13,800 M-1cm-1 (252.5 nm); excitation maximum: 536 nm; emission maximum: 617 nm.

In this protocol, we describe a method to monitor cell proliferation and death by live-cell imaging of propidium iodide (PI)-stained adherent mammalian cells. PI is widely used to assess cell death. However, it is usually used in end-point assays. Recently

Cancer emergence is associated with a series of cellular transformations that include acquired drug resistance followed by tumor metastasis. Matrix metalloproteinases (MMPs) and Hsp90 chaperone are implicated in tumor progression, however, they are not studied in the context of drug

The Hsp90 chaperone has become the attractive pharmacological target to inhibit tumor cell proliferation. However, tumor cells can evolve with mechanisms to overcome Hsp90 inhibition. Using human neuroblastoma, we have investigated one such limitation. Here, we demonstrate that neuroblastoma cells

The altered molecular pathways in response to chemotherapeutic interventions impose limitations on breast cancer treatments. Therefore, understanding the outcome of these alternative pathways may help in improving the chemotherapy. In this study, using hormone responsive and hormone independent breast cancer
