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°C for up to one week. The immunization strategy should be optimized (antigen dose, regimen and adjuvant).

Description

This recombinant human claudin-18.2 (CLDN 18.2) is prepared in mammalian cells. Its target gene encodes the full human claudin-18.2 (CLDN 18.2), containing a 10xHis-tag at the C-terminus. The CLDN 18.2 protein has been validated to be active through a functional ELISA. Immobilized human CLDN 18.2 protein can bind to the recombinant anti-CLDN 18.2 monoclonal antibody. And the EC50 is 5.225-9.256 ng/ml. In the WB assay, this CLDN 18.2 protein was detected by the mouse anti-6xHis monoclonal antibody. Three bands appeared on the gel electrophoresis, respectively corresponding to monomer, homodimer, homotrimer of the CLDN 18.2.

CLDN 18.2, the isoform of CLDN 18, is a tight junction protein exclusively expressed in differentiated epithelial cells of gastric mucosa under normal physiological conditions. Studies have demonstrated that CLDN 18.2 was highly expressed in primary gastric malignancies and post-metastatic types of cancer, including carcinomas of the pancreas, esophagus, ovaries, and lungs. Therefore, CLDN 18.2 has become an ideal target for researchers to develop immunotherapies for solid tumors such as gastric cancer and pancreatic cancer.

Review: I used the CSB-MP005498HU (A5) product for an ELISA experiment, and the EC50 was measured to be 7.918-13.26 ng/ml. The protein showed good binding activity. This product is a popular target protein used as a predictive biomarker for gastric cancer and is a commonly used protein in our company\'s research field. Your company\'s product has shown excellent performance, and I will continue to purchase it.
