CRISPR knockout cell lines are engineered through targeted genome editing to eliminate gene function, supporting studies of cellular biology, disease mechanisms, and drug discovery.
4T1 is a murine mammary carcinoma cell line selected as a 6-thioguanine-resistant variant from the 410.4 tumor without mutagen treatment. The cells are used as an aggressive mouse breast cancer model and are capable of spontaneous metastasis in syngeneic BALB/c mice. 4T1 is widely applied in studies of breast cancer progression, tumor metastasis, immune responses, and evaluation of anticancer therapies, particularly in immunocompetent mouse models.
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.

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.
For research use only. Not intended for human or animal clinical trials, therapeutic or diagnostic use
