Overview

ATP is a marker for cell viability due to its presence in all metabolically active cells. ATP concentration declines rapidly when cells undergo necrosis or apoptosis, and so monitoring ATP is a good indicator of cytotoxic, cytostatic and proliferation effects.

Our ATPlite 1step ATP luminescence assays use patented technologies to measure cell proliferation and cytotoxicity in mammalian cells based on the production of light caused by the reaction of ATP with added luciferase and D-luciferin.

Features and benefits:

  • Simple and reproducible: only one reagent addition step, no separation steps
  • Suitable for both 96- and 384-well microplates
  • Linear correlation between cell number and luminescent signal: up to 50,000 cells per well for 96-well microplates and 12,500 cells per well for 384-well microplates
  • Designed for continuous process systems: luminescence should be measured between 0 and 30 minutes after reagent addition and plate shaking
  • Homogeneous: no cell harvesting or centrifugation required
  • High sensitivity: able to detect down on one cell per well
  • Reduced Phenol Red dependency
  • High light-output: assay can be used with less sensitive luminescence readers such as multi-label readers
  • Fast: no luminescence signal stabilization time required

An alternative format of this assay is also available. The ATPlite assay has separate cell lysis and luminescent signal generation steps. This allows for a more stable signal, with half-life of at least 4 hours.

Application Note

Multi-Parametric Assessment of EGF Treatment Effects on Signaling Pathways, Growth and Proliferation Using AlphaLISA SureFire Ultra and Cellular Imaging

In this application note, we demonstrate an efficient cell-based workflow for the assessment of EGF treatment effects in a cellular model of human skin cancer.

Treatment effects on several intracellular signaling pathways were examined using PerkinElmer’s homogeneous, no-wash AlphaLISA® SureFire® Ultra assays. To determine concurrent time-dependent effects of different EGF concentrations on cellular health and proliferation, ATP concentrations were assessed with ATPlite™ 1step luminescence assay and cultures were fluorescently labeled, imaged and analyzed using the Operetta CLS™ high-content analysis system.

Rapid, No-wash Measurement of Immune Checkpoint Molecules and Cytokines in Co-cultures of Immune Cells and Cancer Cell Lines

Breast cancer tumors can adapt to immune cell infiltration by responding to the increased concentration of interferon gamma (IFN-ɣ) and other cytokines secreted by subsets of T lymphocytes with the upregulation of the immune checkpoint proteins such as Programmed cell death ligand 1 (PD-L1). These checkpoint proteins allow the tumors to evade immune targeting and reduce the immune response, thus promoting tumor progression.

In this application note, you will learn:

  • How exogenous addition of IFN-ɣ effects the expression of PD-L1 and secretion of several cytokines in cultures of HCC38 cells (a triple-negative breast cancer cell line)
  • How co-culturing activated immune cells and breast cancer cells stimulates differential expression of some immune checkpoint and inflammatory biomarkers compared to culturing cells alone with PBMC-conditioned media
  • How to rapidly measure multiple biomarkers in cell culture supernatant and lysates from the same wells of a culture dish to examine protein expression profiles from cancer and immune cell culture models using AlphaLISA® assays together with ATPlite 1step and the EnVision® multimode plate reader.

Using AlphaLISA Biomarker Kits to Assess Effects of PBMC-Conditioned Media on 3D and 2D Cell Culture Models of Breast Cancer

Various cytokines are secreted during an active immune response that can have modulatory effects on target cell populations, including interferon gamma (IFN-ɣ), tumor necrosis factor alpha (TNFa) and several interleukins.

In this application note, you will learn how we investigated:

  • The effects of secreted factors on a triple-negative breast cancer cell line by treatment with conditioned media from activated PBMCs
  • Whether the modulatory effects of cytokines secreted by infiltrating immune is different when studied in 3D cell cultures
  • How to detect and quantify multiple immune-modulated proteins from the same wells in complex cell models grown in 3D spheroid microplates and traditional 2D cell culture using AlphaLISA® technology and EnVision® multimode plate reader in a workflow with ATPlite 1step and Opera® Phenix high-content screening system

Cell-Based Assays: Purposeful Screens for Better Results

Over these last few decades there has been a growing trend in drug discovery to use cellular systems and functional assays, in addition to biochemical assays, for the characterization of new potential therapeutics. The ability to study the interaction between a candidate drug and its target within the context of a whole, intact cell allows for more physiologically relevant data to be obtained. However, such assays are more complex than traditional biochemical assays as such facts as membrane permeability, cellular metabolism, cell variability, additional binding partners, and signal transduction must be considered.

To help you navigate the complexities in designing cell-based assays, we have gathered insights collected over the years and compiled them to provide you with elements to consider when setting up your cell-based assays. After all, any assay, biochemical or cell-based, is only as good as its design.
