Overview Service Process Examples and Solutions Frequently Asked Questions

Overview

Yeast Surface Display Screening is a technique used to screen proteins with specific functions, based on Yeast Surface Display.

The experimental method process generally includes the following steps:

Constructing an expression library: Firstly, it is necessary to connect the protein genes of interest to the expression vector, and then import them into yeast strains expressed on the surface of yeast to construct an expression library.
Attachment fixation: The molecules to be screened (such as antibodies, enzymes, etc.) are combined with the proteins to be screened to form a complex.
Screening: Co incubate the complex with the constructed expression library, and after a series of washing steps, leave the complex that binds to the target protein, while the remaining non binding compounds are washed away.
Separation: Separate the remaining yeast that binds to the target protein, and further analyze its interaction with molecules.

Through this method, proteins with specific functions can be efficiently screened for further research or application.

Service Process

The process of yeast surface display screening involves several critical and interrelated steps:

Project Consultation: Collaborating with researchers to define specific screening requirements, including the target protein, library size, and selection criteria.
Library Construction: Constructing large and diverse libraries of protein variants using techniques such as random mutagenesis, DNA shuffling, or synthetic library design.
Yeast Transformation: Introducing the library into yeast cells to display the protein variants on the cell surface.
Screening and Selection: Performing high-throughput screening and selection based on binding affinity, stability, or activity using techniques such as fluorescence-activated cell sorting (FACS) or magnetic-activated cell sorting (MACS).
Hit Identification: Identifying and isolating yeast cells displaying proteins with desired properties from the screened population.
Characterization and Validation: Characterizing the selected protein variants to confirm their improved properties using methods such as flow cytometry, binding assays, and functional assays.
Optimization and Iteration: Refining the selected protein variants through additional rounds of mutagenesis and screening to further enhance their properties.
Reporting and Consultation: Providing a detailed report of the findings and offering further consultation to interpret the results and plan subsequent research steps.
