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.
ZFP91 (ZFP91 zinc finger protein, atypical E3 ubiquitin ligase) encodes a zinc finger protein with ubiquitin ligase activity that regulates cellular signaling pathways. ZFP91 functions as a regulator of the non-canonical NF-κB pathway and contributes to control of signal-dependent gene expression.
The K-562 cell line was established by Lozzio and Lozzio in 1970 from the pleural effusion of a 53-year-old female patient with chronic myeloid leukemia (CML) in blast crisis. The cells carry the BCR-ABL1 e14-a2 (b3-a2) fusion gene and exhibit characteristics of myeloid leukemia cells, including hemoglobin production. K-562 is a human leukemia cell model widely used for studying CML biology, myeloid differentiation, hematopoietic signaling, and immune cell interactions, including applications as an in vitro target model in natural killer (NK) cell assays.
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.
