Overview

Ubigene gene knockout cell lines mediated by optimized CRISPR-Cas9 technology provide reliable in vitro models for investigating gene function, signaling pathways, disease mechanisms, and therapeutic targets.

4T1 is a murine mammary carcinoma cell line selected as a 6-thioguanine-resistant variant from the 410.4 tumor without mutagen treatment. The cells are used as an aggressive mouse breast cancer model and are capable of spontaneous metastasis in syngeneic BALB/c mice. 4T1 is widely applied in studies of breast cancer progression, tumor metastasis, immune responses, and evaluation of anticancer therapies, particularly in immunocompetent mouse models.

Each knockout cell line is validated by STR authentication, sterility testing (bacteria/fungi), and mycoplasma screening. Genotype is confirmed by two rounds of PCR and Sanger sequencing. Only clones that pass all QC criteria are released, ensuring reliable identity and performance for downstream applications.

KO Cell Construction Strategy

Adopting Red Cotton CRISPR Gene Editing Designer (www.rc-crispr.com), two sgRNAs targeting the Fn1 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into 4T1 cells via electroporation or lentiviral transduction. Single-cell clones are then generated using the limiting dilution method. Genomic DNA from individual clones is subjected to nucleic acid lysis and PCR amplification using the EZ-editor™ Monoclone Genotype Validation Kit (Cat# YK-MV-1000). The edited loci are further verified by Sanger sequencing to confirm the genotype. After secondary validation and quality confirmation, Fn1 Knockout cell line (4T1) is expanded and cryopreserved for downstream applications.

Product Overview

Fn1 Knockout cell line (4T1)

The Fn1 Knockout cell line (4T1) is generated by targeted disruption of the Fn1 gene in 4T1 cells. This cell line is designed to investigate the role of Fn1 in cellular function and gene regulation, as well as its potential involvement in disease-related pathways.

Quality Control

All KO cell products are tested and confirmed to be free of bacterial, viral, mycoplasma contamination, and other adventitious agents.

Applications

For research use only. Not intended for use in diagnostic, therapeutic, clinical, or other applications.

Key Advantages

Easy to use

Cas9 cell lines in our cell bank can stably express Cas9 protein. Each Cas9 Stable Cell Line is easy to use and enables gene knockout simply by transfecting gRNA, while transfection of gRNA and donor DNA results in gene knock-in or point mutations

High-efficient KO

These Cas9 stable cell lines have been used to construct the KO cell lines for various genes, gene KO efficiency 5-10 times improved.

Curated cells

Selected cells, low passages, good cell condition, high activity, applicable for all kinds of gene-editing experiments.
