Tango™ CCR5- bla U2OS Cells

Category: Products & Services > Kits & Assays > Cell Based Assay Kits > GPCR Cell Based Assay Kits

For Academic pricing please login or contact us at discoverysciences@invitrogen.com. The Tango™ CCR5- bla U2OS cells contain the human Chemokine (C-C Motif) Receptor 5 (CCR5) linked to a TEV protease site and a Gal4-VP16 transcription factor stably integrated into the Tango™ GPCR- bla U2OS parental cell line. This parental cell line stably expresses a beta-arrestin⁄TEV protease fusion protein and the beta-lactamase ( bla ) reporter gene under the control of a UAS response element. The Tango™ CCR5- bla U2OS cells are functionally validated for Z' and EC 50 concentrations of MIP-1a. In addition,...

EnzChek® Lysozyme Assay Kit - 400 Assays

Category: Products & Services > Kits & Assays > Enzyme Detection & Activity Assays > Other Enzyme Assay Kits

The EnzChek® Lysozyme Assay Kit provides researchers with a simple and sensitive assay to measure lysozyme acitivty in solution. The assay measures lysozyme activity on Micrococcus lysodeikticus cell walls, which are labeled to such a degree with fluorescein that the fluorescence is quenched. Lysozyme action can relieve this quenching, yielding a dramatic increase in fluorescence that is proportional to lysozyme activity.

Amplex® Red Hydrogen Peroxide/Peroxidase Assay Kit - 500 assays

Category: Products & Services > Kits & Assays > Cell Analysis Kits > Cell Metabolic Assay Kits

The Amplex® Red Hydrogen Peroxide/Peroxidase Assay Kit contains a sensitive, one-step assay that uses the Amplex® Red reagent (10-acetyl-3,7-dihydroxyphenoxazine) to detect hydrogen peroxide (H 2 O 2 ) or peroxidase activity. The Amplex® Red reagent, in combination with horseradish peroxidase (HRP), has been used to detect H 2 O 2 released from biological samples, including cells, or generated in enzyme-coupled reactions. Furthermore, Amplex® Red reagent can be used as an ultrasensitive assay for peroxidase activity when H 2 O 2 is in excess. In the presence of peroxidase, the Amplex® Red reag...

LIVE/DEAD® Violet Viability/Vitality Kit, for 405 nm excitation

Category: Products & Services > Kits & Assays > Cell Analysis Kits > Cell Vitality Assay Kits

The LIVE/DEAD® Violet Viability/Vitality Kit provides a two-color fluorescence cell viability and vitality assay that is based on the simultaneous determination of live and dead cells with two probes that measure recognized parameters of cell health: plasma membrane integrity and intracellular esterase activity. Calcein violet AM and aqua-fluorescent reactive dye are optimal dyes for this application; both dyes utilize the violet laser allowing other laser lines to be used for conventional fluorochromes.
