产品声明
- For Research Use Only
All products available through the MiaoLing Plasmid Platform are intended for research use only. They are not intended for clinical trials or for use in humans, including oral administration, injection, or therapeutic use in vivo or ex vivo. - Plasmid Sequence and Experimental Performance
Plasmid products are provided and sold based on the corresponding reference/template plasmid. MiaoLing guarantees the accuracy of the specified gene sequence based on our sequencing results, but does not guarantee downstream experimental performance, including gene expression, transfection efficiency, protein expression, or other experimental outcomes. - Sequence Verification of Certain Vector Products
For certain vector products, even the original manufacturer may not have fully verified the complete plasmid sequence. If the sequence of the key functional regions has been confirmed to be correct, the product will be considered a correct and usable vector for research purposes. - After-Sales Period for Small-Pack Plasmid Products
The after-sales service period for small-pack plasmid products is three months from the date of receipt. Customers are advised to transform and process the plasmid promptly after receipt. After the three-month period, a new purchase may be required for further support or replacement. - Research-Related Risks and Limitation of Liability
Scientific research is inherently exploratory and involves a significant degree of uncertainty. To the maximum extent permitted by applicable law, MiaoLing shall not be liable for any additional economic losses, indirect losses, or other liabilities arising from the use of our products or from research outcomes. - Citation in Chinese Publications
