PD-1/PD-L1 (cyno) AlphaLISA Binding Kit, 500 Assay Points

The AlphaLISA® cyno PD-1/PD-L1 binding kit is designed for the detection of binding activity between cyno PD-1 and PD-L1, using a fast and simple homogeneous AlphaLISA assay (no wash steps). This assay can be used to screen for small molecules that inhibit binding, as a competitive ligand binding (CLB) assay to screen therapeutic blocking antibodies, and for potency assays.

For research use only. Not for use in diagnostic procedures.

Overview

AlphaLISA features:

  • No-wash steps, no separation steps
  • ELISA alternative technology
  • Sensitive detection
  • Broad range of affinities
  • High avidity
  • Results in less than 3 hours
  • Half the time of an ELISA assay

AlphaLISA® technology allows the detection of molecules of interest in buffer, cell culture media, serum and plasma in a highly sensitive, quantitative, reproducible and user-friendly mode. In an AlphaLISA assay, a Biotinylated Anti-Analyte Antibody binds to the Streptavidin-coated Alpha Donor beads, while another Anti-Analyte Antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

The AlphaLISA cyno PD-1/PD-L1 binding kit allows determination of cross-reactivity of human anti-PD-1 or PD-L1 reagents with cyno proteins, as well as development or screening of novel cyno PD-1 and PD-L1 reagents that block the binding of this interaction. Using the AlphaLISA cyno PD-1/PD-L1 binding assay, small molecule antagonists or large molecule therapeutics and blocking antibodies can be screened in microplate format. Please note an AlphaLISA human PD-1/PD-L1 binding assay is also available for concurrent studies

Application Note

Evaluating the Specificity of PD-1 and PD-L1 Blocking Antibodies Using AlphaLISA Human and Mouse PD-1/PD-L1 Binding Kits

Mouse pharmacological models continue to play a large role in the study of human disease, and mouse tool reagents have shown high utility in immunology and cancer research for decades. It can often be quicker to learn about immunology and the regulation of immune responses using a syngeneic mouse model. However, working in mouse systems can often require the development of separate mouse reagents, if the therapeutic agent of interest does not cross-react with mouse. Find out how the AlphaLISA® human PD-1/PD-L1 and AlphaLISA mouse PD-1/PD-L1 binding assays provide a fast, powerful, homogeneous platform for obtain binding potencies from potential novel drug candidates.

Screening for Inhibitors of PD-1 and PD-L1 Binding with AlphaLISA Technology

Many tumor cells, which under normal, healthy conditions would be recognized by the body’s T cells and thereby targeted for destruction, have developed ways to evade the host immune system by taking advantage of immune checkpoint pathways. Among the most promising approaches to activating therapeutic antitumor immunity is through the blockade of immune checkpoints. The programmed cell death-1 (PD-1) immune checkpoint pathway is a negative regulator of T-cell immune function. When PD-1 is bound to programmed cell death-ligand 1 (PD-L1), T cell response is suppressed. Inhibitors that block PD-1/PD-L1 complex formation lead to increased activation of T-cells and immune system functions, allowing the body’s immune system to identify and attack tumor cells. So far, several anti-PD-1 or PD-L1 monoclonal antibodies have been developed to treat a variety of cancers, including non-small cell lung carcinoma (NSCLC), metastatic melanoma and renal cancer. The promise of therapeutically exploiting this pathway has created a need for more robust, straight-forward assays to identify and qualify potential inhibitors which interrupt PD-1/PD-L1 binding. Find out how AlphaLISA® technology provides a simple, homogenous, straightforward method for detecting PD-1/PD-L1 binding.
