Recombinant Human CLU protein, His-tagged

• Cat.No.: CLU-11H
• Product Overview: Recombinant Human CLU protein (Asp23-Arg227 (β chain) & Ser228-Glu449 (α chain)), fused to His tag at C-terminus, was expressed in human 293 cells (HEK293).

Specification

• Description: Clusterin (CLU) is also known as dimeric acidic glycoprotein (DAG protein), testosterone repressed prostate message-2 (TRPM-2), sulfated glycoprotein-2 (SGP-2) and complement lysis inhibitor (CLI), is a secreted multifunctional glycoprotein protein which belongs to the clusterin family. Intracellular cleavages of the precursor of clusterin remove the signal peptide and generate comparably sized α and β chains which are secreted as an 80 kDa N­glycosylated disulfide­linked heterodimer. DAG protein is predominantly expressed in adult testis, ovary, adrenal gland, liver, heart, and brain and in many epithelial tissues during embryonic development. Clusterin involve in several basic biological events such as cell death, tumor progression, and neurodegenerative disorders. Upregulation of clusterin mRNA and protein levels detected in diverse disease states and in in vitro systems have led to suggestions that it functions in membrane lipid recycling, in apoptotic cell death, and as a stress-induced secreted chaperone protein, amongst others.
• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 um filtered solution in PBS, pH7.4, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 50.9 kDa (Asp23-Glu449, α chain 24.5 kDa + β chain 27 kDa) and was cleaved into α chain and β chain, which form a heterodimer linked by disulfide bonds. DTT reduced protein migrates as 39 kDa and 40 kDa bands in SDS-PAGE due to glycosylation, corresponding to the cleaved β chain, and α chain respectively.
• Protein length: 427
• Endotoxin: Less than 1.0 EU per ug by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
