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.

ZNF281 (zinc finger protein 281) encodes a zinc finger transcriptional regulator with sequence-specific DNA-binding and transcriptional repressor activities. It participates in regulation of gene expression through RNA polymerase II-dependent transcription and can also positively regulate DNA-templated transcription in specific contexts. ZNF281 is therefore relevant to studies of transcriptional regulation, chromatin-associated gene control, and cellular processes governed by changes in gene expression.

AGS is a human gastric adenocarcinoma cell line established from a primary stomach tumor of a 54-year-old female patient who had not received prior anticancer treatment. The cells are derived from gastric adenocarcinoma and are used as a model for studying gastric cancer biology, tumor-related signaling pathways, infection-related mechanisms, and therapeutic responses. AGS cells have been reported to carry persistent parainfluenza virus type 5 (PIV5) infection.

Before delivery, each clone is authenticated by STR, tested for sterility and mycoplasma, and genotype‑verified by two‑round PCR‑sequencing. Comprehensive QC data accompany every shipment to support reproducible research.

KO Cell Construction Strategy

Adopting Red Cotton CRISPR Gene Editing Designer (www.rc-crispr.com), two sgRNAs targeting the ZNF281 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into AGS 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, ZNF281 Knockout cell line (AGS) is expanded and cryopreserved for downstream applications.

Product Overview

ZNF281 Knockout cell line (AGS)

The ZNF281 Knockout cell line (AGS) is generated by targeted disruption of the ZNF281 gene in AGS cells. This cell line is designed to investigate the role of ZNF281 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.
