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.

ESRRG (estrogen related receptor gamma) encodes an orphan nuclear receptor belonging to the estrogen-related receptor family. It contains a conserved C4-type zinc-finger DNA-binding domain and can activate transcription through estrogen response and steroidogenic factor 1 response elements without requiring a known ligand. ESRRG shares target genes and regulatory partners with estrogen receptors and may influence estrogen signaling, cellular proliferation, DNA methylation, and osteoblast differentiation.

An ovarian endometrioid adenocarcinoma model derived in situ from the ovary of a woman is represented by A2780. The human cells are classified as an ovarian endometrioid adenocarcinoma and exhibit low-level microsatellite instability. Documented alterations include PIK3CA p.Glu365Lys, homozygous PTEN deletion of residues 128–130, and RRAS2 p.Gln72Leu.

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 ESR1 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into A2780 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, ESR1 Knockout cell line (A2780) is expanded and cryopreserved for downstream applications.

Product Overview

ESR1 Knockout cell line (A2780)

The ESR1 Knockout cell line (A2780) is generated by targeted disruption of the ESR1 gene in A2780 cells. This cell line is designed to investigate the role of ESR1 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.
