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.

CREB1 (cAMP responsive element binding protein 1) encodes a transcription factor belonging to the leucine zipper family of DNA-binding proteins. CREB1 binds cAMP-responsive elements in gene regulatory regions and is activated through phosphorylation by signaling kinases. It mediates transcriptional responses to cAMP and hormonal signals, contributing to regulation of cellular processes including proliferation, differentiation, and survival.

143B is a human osteosarcoma cell line derived indirectly from the HOS osteosarcoma cell line. The cells are deficient in thymidine kinase (TK−) and resistant to bromodeoxyuridine (BUdR). 143B is used as a model for studying osteosarcoma biology, tumor metabolism, and genetic selection systems involving thymidine kinase deficiency.

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 CREB1 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into 143B 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, CREB1 Knockout cell line (143B) is expanded and cryopreserved for downstream applications.

Product Overview

CREB1 Knockout cell line (143B)

The CREB1 Knockout cell line (143B) is generated by targeted disruption of the CREB1 gene in 143B cells. This cell line is designed to investigate the role of CREB1 in cellular function and gene regulation, as well as its potential involvement in disease-related pathways.

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.
