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.

QSER1 (glutamine and serine rich 1) encodes a glutamine- and serine-rich protein whose specific molecular and cellular functions are not sufficiently characterized in the available information. The current annotation primarily provides limited information about its cellular context without establishing a defined enzymatic activity, signaling pathway, or biological process. Further functional studies are required to determine the molecular role of QSER1 and the consequences of its disruption in cellular models.

BEAS-2B is an immortalized human bronchial epithelial cell line established from normal bronchial epithelium obtained from non-cancerous individuals. The cells were immortalized using a replication-defective SV40/adenovirus 12 hybrid (Ad12SV40) and cloned. BEAS-2B cells express epithelial markers including keratins and SV40 T antigen and can undergo squamous differentiation in response to serum exposure. The cell line is widely used as a model for studying normal airway epithelial biology, respiratory infection mechanisms, epithelial differentiation, environmental toxicity, and carcinogenesis.

Comprehensive quality control includes STR authentication, sterility testing (bacteria and fungi), and mycoplasma screening to ensure purity and performance. Genotype is confirmed by two rounds of PCR and Sanger sequencing, and complete validation reports are provided for make-to-order products.

KO Cell Construction Strategy

Adopting Red Cotton CRISPR Gene Editing Designer (www.rc-crispr.com), two sgRNAs targeting the QSER1 gene are designed to generate a knockout strategy. The two sgRNA sequences are subsequently cloned into the EZ-editor™ vector and introduced into BEAS-2B 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, QSER1 Knockout cell line (BEAS-2B) is expanded and cryopreserved for downstream applications.

Product Overview

QSER1 Knockout cell line (BEAS-2B)

The QSER1 Knockout cell line (BEAS-2B) is generated by targeted disruption of the QSER1 gene in BEAS-2B cells. This cell line is designed to investigate the role of QSER1 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.
