translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Protein Length
Full Length
Tag Info
C-terminal 10xHis-tagged (This tag can be tested only under denaturing conditions)
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-81°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Description
Claudin-3 is a critical tight junction component frequently overexpressed in ovarian, breast, and colorectal cancers, making it a high-value target for antibody development and tumor metastasis research. This full-length human CLDN3 (residues 1–220) is presented on virus-like particles produced in mammalian cells, preserving the native four-transmembrane topology essential for conformational epitope recognition. Functional ELISA confirms binding to an anti-CLDN3 recombinant antibody with an EC50 of 23.62–34.37 ng/mL, directly supporting antibody screening, validation campaigns, and integrin-ligand or receptor-ligand binding studies where proper extracellular loop presentation is required. The VLP format maintains membrane protein orientation suitable for cell migration and invasion assay development, and endotoxin levels below 1.0 EU/μg align with standards expected in immune cell trafficking experiments and functional screening workflows.
