| Description | The CLDN4 Protein Human is produced in E. coli, and its molecular weight is 10.63 kDa. The protein containing 93 amino acid residues of the human CLDN4,10 amino acid N-Terminal HisTag residues and 8 additional amino acid PreScission protease cleavage site. The protein is a fusion protein consisting of two extracellular domains of claudin-4 linked together with the PreScission protease LEVLFQGP cleavage site. |
| Expression host | Escherichia Coli. |
| Formulation | Filtered (0.4 um) and lyophilized from 0.5 mg/ml in 0.05M Acetate buffer pH-4. |
| Protein Background | CLDN4 encodes an integral membrane protein that is a member of the claudin family. CLDN4 is a factor of tight junction strands and takes part in internal organ development and function in pre- and postnatal life. CLDN4 is removed in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. |
| Purity | Greater than 90.0% as determined by SDS-PAGE. |
| Reagent Appearance | Filtered White lyophilized (freeze-dried) powder. |
| Solubility | It is recommended to add 0.1M Acetate buffer pH4 to prepare a working stock solution of approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10ug/ml. In higher concentrations the solubility of this antigen is limited. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture. |
| Stability | Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C. |
| Synonyms | Claudin 4, CPE-R, CPE-receptor, Clostridium perfringens enterotoxin receptor 1, WBSCR8, Williams-Beuren syndrome chromosomal region 8 protein, CPETR1. |
