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.
GPR155 (G protein-coupled receptor 155) encodes a protein associated with the lysosomal membrane and extracellular exosomes that enables cholesterol binding. It is involved in cellular responses to amino acid starvation and cholesterol and in positive regulation of TORC1 signaling. Through these activities, GPR155 may contribute to nutrient sensing, cholesterol-responsive signaling, and regulation of cellular metabolic processes.
Papillary thyroid carcinoma is represented by TPC-1, a human thyroid cancer cell line established from a thyroid tumor. The cells are classified as a human papillary thyroid carcinoma model and carry the characteristic RET/PTC1 rearrangement resulting from fusion of RET with CCDC6. TPC-1 is widely used for studies of thyroid cancer biology and RET-associated oncogenic signaling.
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.

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
These Cas9 stable cell lines have been used to construct the KO cell lines for various genes, gene KO efficiency 5-10 times improved.
Selected cells, low passages, good cell condition, high activity, applicable for all kinds of gene-editing experiments.
