Simple Bioassay, Quality Results

The human immune system responds to conserved damage- and pathogen-associated molecular patterns (DAMPs and PAMPs, respectively) via pattern-recognition receptors (PRRs). One such family of PRRs is the Toll-like receptor (TLR) family. In humans, there are 10 known TLRs, which enable the immune system to sense and respond to damage and danger signals. Modulation of the TLR system, either by agonism or antagonism, has the potential to alter immune and inflammatory responses. Blockade of TLRs may inhibit inflammatory responses while TLR agonists may promote immune responses against pathogens or cancer.

Current methods for assessing the activity of TLR modulators typically rely on primary monocyte-derived macrophages and measurement of functional endpoints, such as cytokine production. These assays are laborious and highly variable due to their reliance on donor cells, complex assay protocols and unqualified assay reagents. As a result, these assays are difficult to establish in a quality-controlled setting.

The TLR Bioassay is a bioluminescent reporter cell-based assay used to measure the potency and stability of TLR agonists.

Bioassay Components and Product Formats

The TLR Reporter Bioassay consists of one genetically engineered cell line:

TLR Bioassay Cells: A monocytic cell line with a stably integrated NanoLuc® (NL) luciferase reporter driven by TLR pathway-dependent response elements.

Thaw-and-Use Kits (1X, 5X):

  • Include TLR Bioassay Cells, cell culture media and assay reagents
  • Recommended for routine use with customer-defined agonist
  • Available in 1X and 5X sizes

Cell Propagation Model format (CPM; Cat.# GA1322):

  • Includes the TLR Bioassay Cells (CPM); these are cryopreserved cells that can be thawed, propagated and banked for long-term use.
  • Use with Bio-Glo-NL™ Luciferase Assay System

Cell Bank format (Cat.# GA6010):

  • Available for customers who are planning to expand and bank their CPM purchase, but they would like to use the cell expansion service offered by Promega.

Workflow

Standard bioassay workflow with cultured cells
Improved bioassay workflow with thaw-and-use cells

Standardized Reagents Improve Results

  • Thaw-and-use format provides significant time and labor savings over traditional methods while reducing variability.
  • Easily amenable to high-throughput workflows.

Assay Principle

The TLR Reporter Bioassay measures the potency and stability of agonists designed to activate TLR signaling.

Assay Performance Data

Representative data for the TLR Reporter Bioassay.

Representative data for the TLR Reporter Bioassay. Panel A. TLR Bioassay Cells were treated with a serial titration of TLR1/2 agonist Pam3CSK4. Panel B. TLR Bioassay Cells were treated with 6ng/ml of Pam3CSK4 in the presence of serial titrations of blocking antibodies as indicated. After a 4-hour induction, Bio-Glo-NL™ Reagent was added and luminescence quantified using the GloMax® Discover System. Data were fitted to four-parameter logistic curves using GraphPad Prism® software. Data were generated using thaw-and-use cells.
