Ubigene gene knockout cell lines mediated by optimized CRISPR-Cas9 technology provide reliable in vitro models for investigating gene function, signaling pathways, disease mechanisms, and therapeutic targets.
ZC3H4 (zinc finger CCCH-type containing 4) encodes a member of the CCCH-type zinc finger protein family. Its zinc finger domain is capable of nucleic acid binding, consistent with a role in RNA- or DNA-associated regulation. ZC3H4 is involved in transcriptional regulation and may contribute to post-transcriptional control of gene expression through interactions with nucleic acids and regulatory proteins.
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.
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.
For research use only. Not intended for human or animal clinical trials, therapeutic or diagnostic use
