HIV HiBiT-PsVLP Bioassay: Measure Viral Neutralization With Ease

Neutralizing antibodies, whether generated through vaccination or produced as therapeutic monoclonal antibodies, are critical for stopping acute and chronic viral infections. Viruses like HIV are important targets for researchers developing vaccines, prophylactic monoclonal antibodies or small-molecule inhibitors, and they need to determine the neutralizing capacity of their therapeutic. However, current methods like PRNT or PNA require infection-competent virus, stringent biosafety measures and cannot be readily implemented in most laboratories.

The HIV HiBiT-PsVLP Bioassay is a simple, easily implemented, robust system that can be used to measure the viral neutralization activity of both antibody and small-molecule inhibitors that block viral entry into target cells. The assay consists of an HIV PsVLP and a target cell line that each contain one piece of a split luciferase technology to provide a low-background and convenient luminescent readout.

Demonstrate HIV Neutralization By Blocking HIV Env Binding to Surface Receptors

Drawing showing the HIV HiBiT-PsVLP Bioassay principle.

 

Principle of HIV HiBiT-PsVLP Bioassay. 1. HiBiT-tagged VLPs pseudotyped with HIV Env protein are added to the HIV (LgBiT) Target cells. 2. In the presence of inhibitors or neutralizing antibodies (nAbs) of HIV entry, the entry/fusion processes of PsVLPs are blocked, thereby preventing HiBiT release, and no luminescent signal is produced. 3. In the absence of inhibitors or nAbs, HIV HiBiT-PsVLPs bind to target cells via CD4, CCR5 or CXCR4 and undergo membrane fusion. HiBiT is released into target cells and binds to LgBiT to generate a luminescent signal.

Assay Workflow: Standardized Reagents to Improve Your Results

Drawing showing the HIV HiBiT-PsVLP Bioassay workflow.
  • Thaw-and-use cell format provides significant time and labor savings over traditional methods while reducing variability.
  • Complete Kit includes all of the required reagents in standardized formats.
  • Easily amenable to high-throughput workflows.

Assay Performance Data

Line graph demonstrating that HIV HiBiT-PsVLP Bioassay is suitable for blocking entry of small-molecule inhibitors.

HIV HiBiT-PsVLP Bioassay is suitable for blocking entry of nAbs and small-molecule inhibitors. HIV (LgBiT) Target cells were incubated with either anti-CD4 antibodies (Panel A) or the anti-viral temsavir (Panel B), binding to gp120 to block the entry of HIV PsVLPs. After incubation, the Bio-Glo-NB™ VLP Reagent was added and luminescence determined in a GloMax® Discover Plate Reader.
