pH-Dependent Antibodies Discovery by Yeast Display Platform

In the ever-evolving field of antibody research, understanding the impact of pH on antibody binding and stability is crucial for developing therapeutic antibodies that can withstand a wide range of physiological environments. By expressing antibodies on the surface of yeast cells and utilizing high-throughput screening, we can rapidly evaluate interactions between the antibodies and target antigens under various pH conditions. This process enables us to identify antibodies that exhibit desirable binding affinities and specificities, particularly those that exhibit changes in binding behavior under different pH conditions - an essential trait for therapeutic antibodies used in environments such as the acidic tumor microenvironment or the varied pH conditions encountered during drug delivery.

How It Works

01Library Construction

We begin by constructing a diverse yeast display antibody library that encodes a wide range of antibody candidates (scFv, Fab, or VHH), designed to maximize the likelihood of finding pH-sensitive binders.

02Screening Under Controlled pH Conditions

We then expose the library to your target antigen under controlled pH conditions and measure binding affinities and select antibody candidates that show pH-dependent binding.

03Binder Identification and Validation

After screening, we identify the most promising antibody candidates that demonstrate strong and selective binding at specific pH levels. These candidates are further validated and characterized for downstream applications.

04Further Characterization & Optimization

Our team provides detailed binding kinetics and structural information for the selected antibodies, ensuring they meet the functional requirements for your therapeutic or diagnostic needs.

High-Throughput Capability

Our platform enables fast, high-throughput screening, providing you with rapid identification of promising antibody candidates without compromising quality.

Applications for pH-Dependent Antibodies

Tumor Targeting

Antibodies that exhibit enhanced binding in acidic environments can be utilized in cancer therapies to selectively target tumor tissues, which are often more acidic than healthy tissues.

Drug Delivery Systems

pH-sensitive antibodies can improve the targeting and release of therapeutics, such as in antibody-drug conjugates (ADCs) that are activated in acidic environments like those found in tumors or intracellular compartments.

Immuno-Oncology

Discover antibodies that can be engineered to selectively bind to antigens in low-pH environments, enabling more effective immune responses against tumors.

Vaccine Development

pH-dependent antibodies can be used in vaccine development to improve delivery systems that rely on targeting specific cells or tissues in different pH conditions.
