Overview

AlphaLISA Acceptor beads conjugated to anti-C-tag antibody. These beads can be used to capture C-tag proteins, and can be used in conjunction with Alpha Donor beads to create AlphaLISA no-wash assays for:

  • Analyte detection
  • Biomarker detection
  • Binding studies
  • Protein-protein interaction
  • Other immunoassays

In a typical Alpha assay, 1 mg of Acceptor beads is sufficient to run 1,000-2,000 wells using a 50 µL reaction volume.

Application Note

Development of Pharmacokinetic (PK) Assays for Detecting Biosimilars Targeting TNF alpha using AlphaLISA

Anti-inflammatory monoclonal antibody drugs that specifically target TNFα, such as Humira®, have been highly successful in the market. As patents expire on these top-selling drugs, effort has been placed on developing biosimilars. Biosimilars differ from small molecule generic drugs in that their chemical structure does not have to be exactly the same as the patented drug. Therefore, the FDA has stringent requirements for proving that the biosimilars have the same efficacy and safety profile as the patented drug. Companies that develop biosimilars are tasked with proving that the biosimilar shows equivalent pharmacokinetics as the patented drug.

Proving “biosimilarity” involves comparing parameters such as overall exposure, absorption, half-life, and clearance time using patient samples. Sensitive, robust, and fast assays are needed to measure these parameters. Traditional methods for detecting and quantifying these drugs in patient samples include time-consuming, wash-based ELISA and MSD methods. In contrast, AlphaLISA allows for fast, no-wash, high-throughput detection and quantification of the drug of interest in a variety of sample matrices. Here, we demonstrate the application of AlphaLISA for detecting biosimilars targeting TNFα.

Alpha Protein-Protein Interaction Quick Start Guide

Alpha has been used to study a wide variety of interactions, including protein:protein, protein:peptide, protein:DNA, protein:RNA, protein:carbohydrate, protein:small molecule, receptor:ligand, and nuclear receptor:ligand interactions. Both cell-based and biochemical interactions have been monitored, and applications such as phage display, ELISA, and EMSA (electrophoretic mobility shift assay) have been adapted to Alpha.

User's Guide To Alpha Assays Protein:Protein Interactions

AlphaScreen® and AlphaLISA® are bead-based assay technologies used to study biomolecular interactions in a microplate format. The acronym “Alpha” stands for Amplified Luminescent Proximity Homogeneous Assay. The assay does not require any washing steps. Binding of proteins or other binding partners captured on the beads leads to an energy transfer from one bead to the other, ultimately producing a luminescent signal.

Technical Note

Development of an AlphaLISA Assay to Measure and Screen Inhibitors of the p53-MDM2 Interaction

Binding events between biomolecules are important components of biological processes and a number of these biomolecular interactions have been targeted for the development of novel therapeutic drugs. p53 is a transcription factor and tumor suppressor protein that is activated in response to cellular stress, and MDM2 was identified as a negative regulator that binds to p53 and tags it for ubiquitination and subsequent degradation.

The p53-MDM2 protein-protein interaction has been an excellent target for therapeutic drugs and therefore makes a good model system for developing an AlphaLISA assay to screen for inhibitors of the interaction. In this technical note, we show how to develop an assay to screen for inhibitors and how to measure a dissociation constant for moderate binding protein-protein interaction using AlphaLISA®.
