Overview Service Process Examples and Solutions Frequently Asked Questions

Overview

Inducible cell lines are engineered to express a gene of interest only in the presence of an inducer, such as doxycycline, tetracycline, or IPTG. This controlled expression system allows researchers to study the temporal effects of gene expression and minimize potential cytotoxic effects. Our services utilize advanced technologies and methodologies to develop high-quality, inducible cell lines tailored to your specific requirements.

The following is the general experimental method process:

Determine target genes: First, determine the target genes that need to be expressed, which can be genes encoding proteins or RNA.
Choose a suitable cell line: Choose a suitable cell line as the host, commonly used cell lines include HEK293, CHO, etc.
Choose a suitable induction system: Determine the appropriate induction system, such as Tet On/Tet Off system, doxycycline induction system, etc.
Construction of expression vector: Clone the target gene into an appropriate expression vector, ensuring that the expression vector contains the sequence of the inducer.
Transfection and screening: Transfer the constructed expression vector into the selected cell line, and determine the successfully transfected cell line through fluorescence or drug screening.
Inducing expression: Add appropriate inducers to induce cells when needed, and observe the expression of target genes.
Validation: Validate the expressed cell line to confirm the level and controllability of the target gene expression.

Through the above steps, a cell line capable of inducing the expression of target genes can be successfully developed, providing effective tools for subsequent research and experiments.

Service Process

The process of inducible cell line development involves several critical and interrelated steps:

Project Consultation: Collaborating with researchers to define specific cell line requirements, including the target gene(s), inducible system, and intended applications.
Vector Design and Construction: Designing and constructing inducible expression vectors tailored to the specific gene and inducer system.
Cell Line Transfection/Transduction: Introducing the inducible vectors into the host cells using transfection or viral transduction methods to achieve stable integration.
Selection and Clonal Isolation: Selecting successfully modified cells using selectable markers and isolating single-cell clones to ensure clonal purity and stability.
Induction and Optimization: Testing and optimizing the inducible system to ensure controlled and robust gene expression in response to the inducer.
Cell Line Characterization: Characterizing the modified cell lines to confirm inducible gene expression, functionality, and stability using methods such as qPCR, Western blotting, and functional assays.
Validation and Quality Control: Validating the inducible cell lines through comprehensive testing to ensure they meet the desired specifications and are free from contamination or unintended modifications.
Optimization and Scale-Up: Refining the inducible cell line development process based on initial results and scaling up production to meet the required quantities for research or commercial use.
