- 目标基因介绍: Serine/threonine-protein kinase that plays a critical role in initiating innate immune response against foreign pathogens. Involved in Toll-like receptor (TLR) and IL-1R signaling pathways (PubMed:17878374). Is rapidly recruited by MYD88 to the receptor-signaling complex upon TLR activation to form the Myddosome together with IRAK2. Phosphorylates initially IRAK1, thus stimulating the kinase activity and intensive autophosphorylation of IRAK1. Phosphorylates E3 ubiquitin ligases Pellino proteins (PELI1, PELI2 and PELI3) to promote pellino-mediated polyubiquitination of IRAK1. Then, the ubiquitin-binding domain of IKBKG/NEMO binds to polyubiquitinated IRAK1 bringing together the IRAK1-MAP3K7/TAK1-TRAF6 complex and the NEMO-IKKA-IKKB complex. In turn, MAP3K7/TAK1 activates IKKs (CHUK/IKKA and IKBKB/IKKB) leading to NF-kappa-B nuclear translocation and activation. Alternatively, phosphorylates TIRAP to promote its ubiquitination and subsequent degradation. Phosphorylates NCF1 and regulates NADPH oxidase activation after LPS stimulation suggesting a similar mechanism during microbial infections.
- 细胞开发路径: A stable KO cell line was generated using the CRISPR‑RNP approach; Sanger sequencing confirmed 100% knockout efficiency in the KO cell line.
- 应用: A gene knockout cell line with high knockout efficiency, particularly well suited for preliminary functional analyses, the development of complex disease models, precision drug screening, and broad‑scale gene discovery studies.

01. Preheat the complete culture medium in a 37°C water bath.
02. Thaw the cryovial in a 37°C water bath for 1–2 minutes.
03. Transfer the cryovials into a biosafety cabinet and wipe their surfaces with 70% ethanol.
04. Unscrew the cap of the cryovial and gently transfer the cell suspension into a sterile centrifuge tube containing 9 mL of complete culture medium.
05. Centrifuge at room temperature at 125g for 5–7 minutes, then discard the supernatant.
06. Resuspend the cell pellet in 5 mL of complete culture medium, and transfer the cell suspension to a T25 culture flask.
07. Transfer the cells to a 37°C incubator with 5% CO2 for culture.
08. Recommended passage ratio: 1/3 to 1/6; cells reach confluence in 2–3 days. -
01. When the cell confluence in the culture flask reaches 80%–90% or higher, cells can be passaged.
02. Remove the culture medium, PBS, and trypsin (0.25% Trypsin‑EDTA, Gibco 25200‑056) from the 4°C refrigerator, place them in a 37°C water bath, and once their temperature approaches 37°C, take them out. Spray the exterior of the bottles with 75% ethanol, then transfer them to a biosafety cabinet.03. Remove the culture flask to be passaged from the incubator, spray the exterior of the flask with 75% ethanol, and then place it inside a biosafety cabinet.
04. To avoid dispersing the cells, gently rinse the cells along the inner wall of the culture flask with PBS; discard the wash solution, and add 2 mL of PBS to the T25 flask.
05. Add the appropriate volume of trypsin (1.5 mL for a T75 flask, 0.5 mL for a T25 flask), and gently swirl the flask to ensure the enzyme evenly covers the cell‑free surface. Adjust the volume as needed based on the specific conditions. After approximately 1–2 minutes, when most of the cells have detached, add the corresponding volume of complete culture medium to stop the digestion, then use a 5‑mL pipette to gently pipette up and down until all cells are fully detached.
06. Transfer the cell suspension to a 15 mL centrifuge tube, centrifuge at 300 g for 5 minutes, and discard the supernatant.
07. Transfer 5 mL of complete culture medium to resuspend the cells, adjust the seeding ratio as needed, and replenish the culture flask with complete medium—add up to 13–15 mL for a T75 flask and 5 mL for a T25 flask—then supplement with 1% double antibiotic solution.
08. After capping the bottle and tightening the lid, gently shake the vial to ensure uniform cell suspension, then place it in a 37°C incubator with 5% CO2. -
01. Prepare the cryopreservation solution and pre-cool it in advance.
02. Ensure that the cells to be cryopreserved meet the cryopreservation requirements, and verify the following conditions under a microscope: healthy appearance and morphological characteristics, being in the late logarithmic growth phase, and showing no signs of contamination or senescence.
03. Digest and centrifuge the cells (refer to the subculture protocol for specific steps).
04. Resuspend the cells in cryopreservation medium at 1 mL per tube, gently pipette up and down to ensure uniformity, then aliquot into cryovials.
05. Place the cells in a programmed cooling box and freeze them at −80°C.
06. Subsequently, the cells are transferred to a liquid nitrogen tank for long-term storage. - In antibody validation
