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.
ZNF121 (zinc finger protein 121) encodes a nuclear zinc finger protein predicted to function as a sequence-specific transcription factor regulating RNA polymerase II-dependent gene expression. The protein is predicted to bind cis-regulatory regions and modulate transcription of target genes. Its specific genomic targets, interacting partners, and biological functions remain incompletely characterized, and further experimental studies are required to define its contribution to cellular regulation.
HT-29 is a human colorectal adenocarcinoma cell line established from a primary colon tumor of a 44-year-old female patient in 1964. The cells can undergo differentiation into mature goblet-like cells and produce mucin-secreting subclones, such as HT29-MTX, which exhibit characteristics of intestinal epithelial differentiation, including tight junction formation and mucus layer production. HT-29 is widely used as a model for studying colorectal cancer biology, intestinal epithelial differentiation, barrier function, and drug or nanoparticle transport.
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.
