CA was used in elucidating the mechanisms underlying the positive and inotropic and chronotropic ability of CA on isolated superfused guinea pig atria. It may also be used to stimulate and measure the erythrocyte Ca2+ dependent K+ channels as the K+ efflux.
Calcium ionophore III may be used in ionophore-based calcium selective conductometric microsensors for the detection of calcium ions in aqueous solutions. In NIH3T3 and rat1-fibroblast cell cultures, calcium ionophore III along with thapsigargin has been reported to increase the hepatic clock gene Per1 expression in the initial period of treatment.
Ionophore highly selective for Ca2+. Potentiates responses to NMDA but not quisqualate. In cell culture, stimulates nitric oxide production by calmodulin-dependent constitutive nitric oxide synthase.

InChI key	JOEGUDLMKJATMX-UHFFFAOYSA-N

A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and anti-oxidant properties. Curcumin has been cited as a potential chemopreventive agent, in addition to its chemotherapeutic activity. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.

91963-1KT
Cytotoxicity detection kit 91963-1KT
General description
Cytotoxicity LDH Assay Kit-WST is a kit for determination of cytotoxicity by measuring a lactate dehydrogenase (LDH) activity released from damaged cells. LDH is a stable cytoplasmic enzyme present in all types of cells and released into the cell culture medium through damaged plasma membrane. Since Cytotoxicity LDH Assay kit-WST neither reflects the activity of living cells nor is harmful to cells, cytotoxicity can be measured with living cells (homogeneous assay). In addition, it is possible to perform a non-homogeneous assay by using the cell culture supernatant.

After preparation the Working Solution is stable under refrigerated conditions and can readily be used for up to six months.
Features and Benefits
Colorimetric assay system
Utilize for both homo- and non-homogeneous assays
Can be used with and without transferring supernatant
Stable Working Solution (6 months at 0°C)
