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.
ZNF189 (zinc finger protein 189) encodes a Kruppel-like zinc finger protein containing C2H2-type DNA-binding zinc finger repeats. Members of this protein family can regulate gene expression through sequence-specific DNA binding, while KRAB domains found in many related proteins contribute to transcriptional repression. The specific molecular functions of ZNF189 remain incompletely characterized.
The Ishikawa cell line was established from an endometrial adenocarcinoma of a 39-year-old female patient. This human endometrial cancer model exhibits tumorigenic properties, forming well-differentiated adenocarcinomas in athymic nude mice. Ishikawa cells express estrogen and progesterone receptors both in vitro and in induced tumors, and they respond to steroid hormone stimulation. The cells have also been reported to produce corticotropin-releasing hormone, placental alkaline phosphatase, and chorionic gonadotropin. Ishikawa is widely used as a model for studying endometrial cancer biology, hormone receptor signaling, reproductive endocrinology, and endocrine-based therapeutic research.
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.
