| Description |
This Human Claudin-9 (CLDN9) recombinant protein was produced in Mammalian cell, where the gene sequence encoding Human CLDN9 (1-217aa) was expressed with the C-terminal 10xHis tag. The activity was validated. CLDN9 is a tight junction protein. Abnormal expression of CLDN9 will lead to impaired tight junctions function and reduced barrier function, resulting in increased tissue permeability, which will eventually lead to many diseases including hereditary, allergic diseases, infectious diseases of various systems and even tumors. Therefore, CLDN9 is regarded as a potential target for the treatment of cancer or other diseases. |
| Endotoxin | Less than 1.0 EU/ug as determined by LAL method. |
| Activity | Measured by its binding ability in a functional ELISA. Immobilized Human CLDN9 at 10 μg/mL can bind Anti-CLDN6/9 recombinant antibody (CSB-RA005508MA1HU), the EC50 is 24.93-35.47 ng/mL. |

| Form |
Lyophilized powder Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand. |
| Buffer | Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4 |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference. |
| Troubleshooting and FAQs |

| Storage Condition | Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles. |
| Shelf Life | The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. |
| Lead Time | Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time. |
| Notes | Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week. |
