Name : Human Clusterin Protein

Product Source :
Recombinant Human Clusterin Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp23-Glu449.[Accession | P10909-1]

Molecular Weight :
The protein has a predicted MW of 51.2 kDa. The protein migrates to 38-41 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per ug by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Human Clusterin on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. ELISA Data Immobilized Human Clusterin, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-Clusterin Antibody, hFc Tag with the EC50 of 49.2ng/ml determined by ELISA.

Background :
Clusterin (CLU) is a stress-activated, ATP-independent molecular chaperone, normally secreted from cells, that is up-regulated in Alzheimer disease and in many cancers. It plays important roles in protein homeostasis/proteostasis, inhibition of cell death pathways, and modulation of pro-survival signalling and transcriptional networks. Changes in the CLU gene locus are highly associated with Alzheimer disease, and many therapy-resistant cancers over-express CLU.

Synonyms :
Clusterin; Apo-J; Clustrin; SGP-2; Msgp-2; CLU; AAG4; APOJ; CLI; KUB1; SP-40; TRPM2; CLI; KUB1;
