CRISPR knockout cell lines are engineered through targeted genome editing to eliminate gene function, supporting studies of cellular biology, disease mechanisms, and drug discovery.
ZFYVE21 (Zinc finger FYVE-type containing 21) encodes a zinc-binding protein containing a FYVE domain that mediates interactions with specific cellular membranes. ZFYVE21 is localized to endosomes and focal adhesions and may contribute to regulation of endosomal functions and cell adhesion-related processes.
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.
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.
