Overview

Gene knockout cell lines are generated using CRISPR-Cas9 based technology to precisely disrupt target genes, enabling functional genomics research, disease modeling, and target validation.

ZNF639 (zinc finger protein 639) encodes a Kruppel-like zinc finger protein that functions as a sequence-specific DNA-binding transcriptional regulator. It contributes to regulation of gene expression by interacting with target DNA sequences and modulating transcriptional activity.

JIMT-1 is a human breast cancer cell line established from the pleural effusion of a 62-year-old female patient with grade 3 invasive ductal breast carcinoma (T2N1M0) after postoperative radiation therapy. The cells carry amplification of the HER2 oncogene and have been reported to be insensitive to HER2-targeted therapies, including trastuzumab. JIMT-1 is widely used as a model for studying HER2-positive breast cancer biology, mechanisms of therapeutic resistance, and evaluation of novel anti-HER2 treatments.

Comprehensive quality control includes STR authentication, sterility testing (bacteria and fungi), and mycoplasma screening to ensure purity and performance. Genotype is confirmed by two rounds of PCR and Sanger sequencing, and complete validation reports are provided for make-to-order products.

KO Cell Construction Strategy

Adopting Red Cotton CRISPR Gene Editing Designer (www.rc-crispr.com), two sgRNAs targeting the ZNF639 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into JIMT-1 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, ZNF639 Knockout cell line (JIMT-1) is expanded and cryopreserved for downstream applications.

Product Overview

ZNF639 Knockout cell line (JIMT-1)

The ZNF639 Knockout cell line (JIMT-1) is generated by targeted disruption of the ZNF639 gene in JIMT-1 cells. This cell line is designed to investigate the role of ZNF639 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.
