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.

METTL22 (methyltransferase 22, Kin17 lysine) encodes a non-histone lysine methyltransferase that interacts with the DNA repair and replication-associated protein Kin17. Through its methyltransferase activity and interaction with Kin17, METTL22 may contribute to the regulation of cellular processes involving DNA maintenance and mRNA processing. Its precise biological functions and downstream effects remain incompletely characterized.

The 293T cell line is a highly transfectable derivative of the human embryonic kidney (HEK) 293 cell line. Originally designated 293tsA1609neo, it was generated by introducing the SV40 large T-antigen gene and a neomycin resistance gene into an adenovirus-immortalized human embryonic kidney cell subline. The cells express SV40 large T-antigen and support replication of vectors containing the SV40 origin of replication. Due to their high transfection efficiency and favorable properties for gene expression and protein production, 293T cells are widely used for molecular biology studies, recombinant protein expression, and production of viral vectors including retroviral and lentiviral systems.

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 METTL22 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into 293T 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, METTL22 Knockout cell line (293T) is expanded and cryopreserved for downstream applications.

Product Overview

METTL22 Knockout cell line (293T)

The METTL22 Knockout cell line (293T) is generated by targeted disruption of the METTL22 gene in 293T cells. This cell line is designed to investigate the role of METTL22 in cellular function and gene regulation, as well as its potential involvement in disease-related pathways.

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.
