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.

The U-2932 cell line was established in 1996 from the ascites of a 29-year-old female patient with diffuse large B-cell lymphoma (DLBCL), following a history of advanced-stage Hodgkin lymphoma treated with multiple chemotherapy and radiotherapy regimens. The cells belong to the activated B-cell (ABC-like) subtype of DLBCL and have been reported to overexpress BCL2, BCL6, and p53. U-2932 contains two distinct subpopulations with different surface expression patterns of CD19, CD20, and CD38, reflecting intraline heterogeneity. This human lymphoma cell line is used as a model for studying B-cell malignancies, tumor heterogeneity, molecular alterations, and therapeutic responses in diffuse large B-cell lymphoma.

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 SIRT1 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into U-2932 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, SIRT1 Knockout cell line (U-2932) is expanded and cryopreserved for downstream applications.

Product Overview

SIRT1 Knockout cell line (U-2932)

The SIRT1 Knockout cell line (U-2932) is generated by targeted disruption of the SIRT1 gene in U-2932 cells. This cell line is designed to investigate the role of SIRT1 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.
