CRISPR knockout cell lines are engineered through targeted genome editing to eliminate gene function, supporting studies of cellular biology, disease mechanisms, and drug discovery.
ZNF703 (zinc finger protein 703) encodes a zinc finger-containing regulatory protein involved in transcriptional and signaling processes. ZNF703 participates in regulation of mammary gland epithelial cell proliferation and transforming growth factor-β receptor signaling and may contribute to cellular responses to estradiol. Its localization to the cytoplasm and nuclear matrix suggests functions extending beyond direct DNA binding. Through these activities, ZNF703 may influence epithelial cell growth and signaling, although its precise molecular mechanisms remain incompletely characterized.
5637 is a human bladder carcinoma cell line established from a primary bladder tumor of a 68-year-old male patient. The cells are known to produce multiple growth factors, including stem cell factor (SCF), interleukins, and colony-stimulating factors. 5637 cells are used as a model for studying bladder cancer biology, tumor-associated signaling, and growth factor regulation.
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.
