- 目标基因介绍: Catalyzes two distinct but analogous reactions: the reversible epimerization of UDP-glucose to UDP-galactose and the reversible epimerization of UDP-N-acetylglucosamine to UDP-N-acetylgalactosamine. The reaction with UDP-Gal plays a critical role in the Leloir pathway of galactose catabolism in which galactose is converted to the glycolytic intermediate glucose 6-phosphate. It contributes to the catabolism of dietary galactose and enables the endogenous biosynthesis of both UDP-Gal and UDP-GalNAc when exogenous sources are limited. Both UDP-sugar interconversions are important in the synthesis of glycoproteins and glycolipids.
- 细胞开发路径: A stable KO cell line was generated using the CRISPR-RNP method; Sanger sequencing confirmed 100% knockout efficiency in the KO cell line.
- 应用: Gene knockout cell lines (KO Cell Lines) with high knockout efficiency are particularly well suited for preliminary functional analysis, the development of complex disease models, precision drug screening, and broad gene discovery research.

01. Pre-warm 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 cryovial to a biosafety cabinet and wipe its surface 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 125g for 5–7 minutes at room temperature, 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: Passaged at a ratio of 1/3 to 1/4; cells will confluence in 2–3 days. -
01. Cell passage can be performed when the cell confluence in the culture flask reaches 80%–90% or higher.
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 remove them when their temperature approaches 37°C. After spraying the surfaces of the bottles with 75% ethanol, transfer them to a biosafety cabinet.03. Remove the culture flask to be passaged from the incubator, spray the flask with 75% ethanol, and place it in a biosafety cabinet.
04. To avoid detaching the cells, rinse them with PBS along the inner wall of the culture flask; discard the wash solution, and add 2 mL to a 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 so the enzyme evenly coats the bottom. Adjust the volume as needed. After approximately 1–2 minutes, when most cells have detached, add the corresponding volume of complete culture medium to stop the digestion, and 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 300g for 5 min, and discard the supernatant.
07. Resuspend the cells in 5 mL of complete medium, adjust the seeding ratio as needed, and replenish the complete medium in the culture flasks—add up to 13–15 mL for T75 flasks and 5 mL for T25 flasks—and supplement with 1% double antibiotic.
08. After capping the bottle and tightening the cap, gently shake the bottle to mix the cells evenly, then place it in a 37°C, 5% CO2 incubator. -
01. Prepare the cryopreservation solution and pre-cool it in advance.
02. Ensure that the cells to be cryopreserved meet the cryopreservation requirements; examine the following conditions under a microscope: healthy appearance and morphological characteristics, appropriate growth phase (late logarithmic phase), and absence of contamination or signs of decline.
03. Digest and centrifuge the cells (refer to the subculture protocol for specific steps).
04. Resuspend the cells in cryopreservation solution at 1 mL per tube, mix thoroughly by pipetting, and aliquot into cryovials.
05. Place the cells in a programmed cooling box and freeze them in a -80°C freezer.
06. The cells are subsequently transferred to a liquid nitrogen tank for long-term storage. - Western blot (WB) analysis was performed simultaneously on lysates from wild-type and KO cells using a specific monoclonal antibody; the target protein band was detected in WT cells but absent or diminished in KO cells.

Cell Line Description
Introduction of target gene
Catalyzes two distinct but analogous reactions: the reversible epimerization of UDP-glucose to UDP-galactose and the reversible epimerization of UDP-N-acetylglucosamine to UDP-N-acetylgalactosamine. The reaction with UDP-Gal plays a critical role in the Leloir pathway of galactose catabolism in which galactose is converted to the glycolytic intermediate glucose 6-phosphate. It contributes to the catabolism of dietary galactose and enables the endogenous biosynthesis of both UDP-Gal and UDP-GalNAc when exogenous sources are limited. Both UDP-sugar interconversions are important in the synthesis of glycoproteins and glycolipids.
Cell development path
A stable KO cell line was generated using the CRISPR-RNP method; Sanger sequencing confirmed 100% knockout efficiency in the KO cell line.
Application
Gene knockout cell lines (KO Cell Lines) with high knockout efficiency are particularly well suited for preliminary functional analysis, the development of complex disease models, precision drug screening, and broad gene discovery research.
