Overview

CRISPR knockout cell lines are engineered through targeted genome editing to eliminate gene function, supporting studies of cellular biology, disease mechanisms, and drug discovery.

ZNF445 (zinc finger protein 445) encodes a zinc finger protein involved in epigenetic regulation of gene expression. It enables binding to methylated double-stranded DNA and contributes to chromosomal CpG island methylation. ZNF445 is particularly involved in epigenetic programming of the female pronucleus and is localized to the nucleus, supporting a role in DNA methylation and transcriptional regulation.

The K-562 cell line was established by Lozzio and Lozzio in 1970 from the pleural effusion of a 53-year-old female patient with chronic myeloid leukemia (CML) in blast crisis. The cells carry the BCR-ABL1 e14-a2 (b3-a2) fusion gene and exhibit characteristics of myeloid leukemia cells, including hemoglobin production. K-562 is a human leukemia cell model widely used for studying CML biology, myeloid differentiation, hematopoietic signaling, and immune cell interactions, including applications as an in vitro target model in natural killer (NK) cell assays.

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 ZNF445 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into K-562 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, ZNF445 Knockout cell line (K-562) is expanded and cryopreserved for downstream applications.

Product Overview

ZNF445 Knockout cell line (K-562)

The ZNF445 Knockout cell line (K-562) is generated by targeted disruption of the ZNF445 gene in K-562 cells. This cell line is designed to investigate the role of ZNF445 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.
