Invitrogen™ GlowQuant™ ATP Cell Viability Assay Kit

Key Features:

Features of GlowQuant™ ATP Cell Viability Assay Kit include:

• High sensitivity ATP detection— Detects low cell numbers, down to ~50 cells/well in a 96-well plate.
• Fast and simple — One-step add-and-read format with minimal hands-on time and results in as little as 10 minutes
• No reagent preparation required — Supplied as a ready-to-use, pre-formulated reagent.
• Stable signal — Bioluminescent glow with a signal half-life > 2 hours for flexible plate reading.
• Quantitative and reliable performance — Linear response over a wide dynamic range for reliable cell-number estimation.
• Microplate reader compatible — Designed for use with standard luminescence microplate readers in 96- and 384-well formats; compatible with automation.

How it Works

The GlowQuant™ assay features a simple add-and-read protocol with no separate lysis step required.

1. Add an equal volume of reagent directly to cultured cells.
2. Mix for 1 minute.
3. Incubate at room temperature for 10–20 minutes.
4. Measure luminescence using a luminometer or compatible microplate reader.

The emitted luminescent signal is proportional to intracellular ATP levels. Because viable cells maintain ATP while damaged or non-viable cells rapidly lose ATP, signal intensity directly reflects the number of metabolically active cells in each well.
