Introduction
Studies indicate that androgen treatment increases Clusterin mRNA and protein levels. Clusterin's interaction with the LDL-Receptor appears significant in membranous glomerulonephritis development. In CaP, Clusterin expression decreases compared to benign controls. Additionally, Clusterin has been implicated in cellular senescence, tumorigenesis, and the photo-oxidative cell death pathway. Furthermore, it serves as a functional tumor marker for diagnosing pediatric large cell lymphoma. Clusterin is activated in acidic environments and can inhibit NF-kappaB signaling by stabilizing IkappaBs, which can limit tumor cell movement. Interestingly, the N-terminal deletion of Clusterin seems crucial for its altered biogenesis in esophageal squamous cell carcinoma.
Description
Produced in HEK293 cells, Canine Clusterin is a glycosylated polypeptide chain comprising 436 amino acids. With a molecular weight of 50.72 kDa, this recombinant protein features a 13 amino acid Flag tag at its N-terminus. Purification is achieved using proprietary chromatographic techniques.
Physical Appearance
White, lyophilized powder.
Formulation
The Canine Clusterin undergoes filtration (0.4µm) and lyophilization from a solution of 0.5mg/ml containing 20mM Tris buffer and 20mM NaCl at a pH of 7.5.
Solubility
To create a working stock solution, add deionized water to achieve a concentration of roughly 0.5mg/ml. Ensure complete dissolution of the lyophilized pellet. Please note that this product is not sterile. Prior to use in cell culture, filter the solution through a sterile filter.
Stability
Lyophilized protein should be stored at -20°C. After reconstitution, aliquot the product to minimize freeze-thaw cycles. Reconstituted protein remains stable at 4°C for a limited period; no changes are observed for up to two weeks at this temperature.
Purity
Purity exceeds 95% as determined by SDS-PAGE analysis.
