Background:

Current antibody screening methods like ELISA and western blot struggle with the increasing volume of novel antibodies.
High-throughput (HT) platforms are needed for rapid antibody identification and characterization.
Phage antibody libraries are a valuable resource for antibody discovery.

Purpose of the Study:

To develop and validate a novel high-throughput protein chip platform for antibody screening.
To enable rapid identification and characterization of single-chain variable fragments (scFv).
To provide a bioinformatics tool for comparing the novel strategy with traditional methods.

Main Methods:

A protein chip displaying recombinant phage particles from a large phage antibody library was developed.
The platform was tested using human recombinant interleukin 8 as a model antigen.
A novel bioinformatics tool was created to compare the new method with existing techniques.

Main Results:

The protein chip platform successfully identified single-chain variable fragments (scFv).
The method demonstrated robustness and relative speed in antibody identification.
The associated bioinformatics tool facilitated comparison with traditional antibody screening approaches.

Conclusions:

The developed protein chip platform offers a powerful and simple methodology for antibody screening.
This approach represents a significant advancement in phage library screening protocols.
The integrated bioinformatics tool enhances the utility and comparability of the novel method.
