Summary
We developed Luciferase Immunoprecipitation Systems (LIPS), a quantitative method for profiling antibody responses to antigens. LIPS offers a sensitive, dynamic range for understanding disease mechanisms and identifying new biomarkers.
Area of Science:
- Immunology
- Biotechnology
- Infectious Diseases
Background:
- Understanding antibody profiles is crucial for disease mechanism insights and biomarker discovery.
- Current methods like ELISA have limitations in sensitivity and antigen preparation.
Purpose of the Study:
- To introduce and detail the Luciferase Immunoprecipitation Systems (LIPS) assay.
- To demonstrate LIPS as a quantitative tool for profiling antibody responses to autoantigens and infectious agents.
Main Methods:
- Developed Luciferase Immunoprecipitation Systems (LIPS) for antibody profiling.
- Implemented a universal format for surveying humoral serological responses.
- Achieved dynamic antibody titer ranges up to 6 log(10).
Main Results:
- LIPS provides highly quantitative antibody titer ranges.
- Profiling with LIPS is more informative than single-antigen ELISA, even for entire pathogen proteomes.
- LIPS reduces time and effort in antigen preparation and assay optimization.
Conclusions:
- LIPS is a sensitive and versatile method for comprehensive antibody profiling.
- This technique facilitates deeper understanding of disease pathogenesis and biomarker identification.
- The protocol enables readily profiling antibody responses to single or multiple antigens.
