CRISPR knockout cell lines are engineered through targeted genome editing to eliminate gene function, supporting studies of cellular biology, disease mechanisms, and drug discovery.
AAR2 (AAR2 Splicing Factor) encodes an RNA splicing factor involved in pre-mRNA processing. The protein participates in spliceosome function and regulation of mRNA maturation.
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.

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.
