Overview Service Process Examples and Solutions Frequently Asked Questions

Overview

mRNA display screening is an experimental technique used to screen protein nucleic acid interactions. This technology connects a series of mRNA encoding different proteins with specific nucleic acid sequences and transcribes and translates them in vitro, thereby binding proteins with specific nucleic acid sequences to form complexes. Then, by screening and sorting these complexes, proteins with specific binding affinity can be quickly and efficiently obtained.

This experimental method typically includes the following steps:

Build mRNA Display Library: Connect different protein coding sequences with mRNA containing specific nucleic acid sequences to form an mRNA Display Library.
Transcription translation: The mRNA Display library is transcribed and translated in vitro to obtain a series of protein nucleic acid complexes.
Screening: Protein nucleic acid complexes are screened using specific nucleic acid sequences to identify complexes with binding affinity.
Sorting: The screened protein nucleic acid complexes are sorted and identified to determine the protein with the highest binding affinity.

By using mRNA Display Screening technology, proteins with specific binding affinity can be quickly and efficiently screened, which is widely used in fields such as protein interaction research and drug screening.

Service Process

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

Project Consultation: Collaborating with researchers to define specific screening requirements, including the target molecule, library size, and selection criteria.
Library Construction: Constructing large and diverse libraries of protein or peptide variants using techniques such as random mutagenesis, DNA shuffling, or synthetic library design.
mRNA Display Library Creation: Linking mRNA to its encoded protein to create a display library for screening.
Screening and Selection: Performing high-throughput screening and selection based on binding affinity, specificity, or activity through iterative rounds of selection.
Hit Identification: Isolating mRNA-protein complexes displaying molecules with desired properties from the screened population.
Characterization and Validation: Characterizing the selected variants to confirm their improved properties using methods such as binding assays, functional assays, and sequencing.
Optimization and Iteration: Refining the selected 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.
