Facile and Modular Pipeline for Protein-Specific Antibody Customization

Area of Science:

• Biotechnology
• Immunology
• Protein Science

Background:

• Antibodies are essential research tools but high-quality, versatile antibodies are often scarce.
• Existing antibody production methods can be costly and inaccessible for small-scale needs.

Purpose of the Study:

• To develop a modular, low-cost pipeline for small-scale antibody customization.
• To generate high-titer, protein-specific antibodies for diverse research applications.

Main Methods:

• Designing soluble antigens based on protein secondary structure.
• Utilizing intein-mediated trans-splicing (TS) for antigen display on a nanoplatform.
• Employing a modular HaloLink resin platform with TS-generated antigens for antibody purification.

Main Results:

• Successfully elicited high titers of protein-specific antibodies.
• Purified antibodies demonstrated excellent performance in immunofluorescence, immunoprecipitation, and western blotting.
• The pipeline proved effective for generating research-grade antibodies.

Conclusions:

• The developed pipeline offers a viable solution for producing customized, high-quality antibodies.
• This approach enhances accessibility to essential tools for protein functional studies.
• The method supports basic science research by providing reliable antibody reagents.
