As an accredited Escherichia Coli factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging for *Escherichia coli* contains 1 mL in a sterile, sealed vial, labeled with hazard warnings and storage instructions. |
| Shipping | Escherichia coli (E. coli) is shipped in leak-proof, clearly labeled, and temperature-controlled packaging, complying with Biosafety Level 1 or 2 regulations, depending on the strain. Packages meet all local and international regulations for the transport of biological materials to ensure safe handling and prevent accidental exposure during transit. |
| Storage | **Escherichia coli (E. coli)** cultures and stocks should be stored in tightly sealed, labeled containers. For short-term storage, keep cultures at 4°C. For long-term storage, suspend cells in 15-20% glycerol and store at -80°C. Ensure containment protocols are followed, and avoid repeated freeze-thaw cycles to maintain viability and prevent contamination. |

Strain specificity: Escherichia Coli strain K12 is used in recombinant protein production, where it enables high-yield expression of target proteins. Growth medium: Escherichia Coli grown in LB medium is used in gene cloning experiments, where it provides rapid biomass accumulation for DNA extraction. Antibiotic resistance: Escherichia Coli with ampicillin resistance is used in plasmid selection processes, where only transformed cells proliferate. Optical density: Escherichia Coli cultured to OD600 of 0.6 is used in IPTG induction protocols, where optimal protein synthesis is achieved. Temperature tolerance: Escherichia Coli stable at 37°C is used in large-scale fermentation, where maximal cell viability and productivity are maintained. Purity grade: Escherichia Coli genomic DNA of >98% purity is used in molecular diagnostics, where reliable PCR amplification is ensured. Plasmid stability: Escherichia Coli with high plasmid retention is used in sequential subculturing, where consistent gene expression is maintained. Doubling time: Escherichia Coli with a doubling time of 20 minutes is used in laboratory stock preparation, where rapid culture expansion is facilitated. Transformation efficiency: Escherichia Coli with >10^8 cfu/μg DNA transformation efficiency is used in synthetic biology projects, where high cloning success rates are obtained. Endotoxin level: Escherichia Coli with endotoxin levels below 0.1 EU/mL is used in biopharmaceutical manufacturing, where product safety is enhanced. |
