Ca++-Induced G Protein Coupled Receptor (GPCR) Activation Monitored via Aequorin Luminescence in the LMax Microplate Luminometer (MaxLine Application Note #42)

Jinfang Liao, M.D., Ph.D. and Evelyn McGown, Ph.D. Molecular Devices Corporation, 8/00 The photoprotein aequorin, a bioluminescent protein from the coelentratejellyfish Aequorea victorea, has proven to be highly sensitive to the trace amount of Ca in cells. The aequorin complex which contains the...

ATP Quantitation in the LMax Microplate Luminometer (MaxLine Application Note #40)

Evelyn McGown, Ph.D. and Michael Su, M.S. Molecular Devices Corporation, 8/00 Adenosine triphosphate (ATP) is present in all living cells. Because the level isstrictly-controlled, assay of ATP can be used as a indicator of viable cell number.ATP measurements are used to monitor raw materials and manufacturing...

DNA Quantitation in the LMax Microplate Luminometer (MaxLine Application Note #37)

Evelyn McGown, Ph.D. and Michael Su, M.S. Molecular Devices Corporation, 8/00 DNA measurements are important for many aspects of molecular biology. Of thespectrophotometric methods available, UV absorbance measurement at 260 nm isthe simplest and has recently gained widespread popularity in the microplateforma...

High Sensitivity, Wide Dynamic Range, Horseradish Peroxidase (HRP) ELISA Using the LMax Microplate Luminometer (MaxLine Application Note #41)

Evelyn McGown, Ph.D. and Michael Su, M.S. Molecular Devices Corporation, 8/00 Immunoassays have traditionally employed colorimetric indicators. As such, multiple dilutions of samples were necessary to ensure that they fell within the dynamic range of the assay. Recently, chemiluminescent immunoassays, with gre...

Dual-Luciferase Quantitation in the LMax Microplate Luminometer (MaxLine Application Note #39)

Evelyn McGown, Ph.D. and Michael Su, M.S. Molecular Devices Corporation, 8/00 Reporter gene assays are used to study eukaryotic gene expression. Dual geneticreporters are commonly used in transient transfections of cultured cells tominimize experimental variability caused by differences in cell number, viabili...

Luciferase Reporter Gene Cells and Recombinant Luciferase Dilutions Studied with the CLIPR Luciferase Assay Kit and the LMax Microplate Luminometer (MaxLine Application Note #38)

Evelyn McGown, Ph.D. , Michael Su, M.S. and Jin Liao, M.D., Ph.D. Molecular Devices Corporation, 8/00 Luciferase from the North American firefly (Photinus pyralis) is very popular foruse in Reporter Gene Assays. The enzyme catalyzes the ATP-dependent oxidationof luciferin with the concomitant release of light...
