UniProtKB acc. No. P10909. Protein identity confirmed by LC-MS/MS.
Purity as determined by densitometric image analysis: > 90%
12 % SDS-PAGE separation of Human Clusterin NATIVE:
- M.W. marker – 14, 21, 31, 45, 66, 97 kDa
- Reduced and boiled sample, 2.5 μg/lane
- Non-reduced and non-boiled sample, 2.5 μg/lane
< 0.1 EU/µg
Filtered (0.4 μm) and lyophilized from 0.5 mg/ml solution in phosphate buffered saline pH 7.5 + 5%(w/v) trehalose.
Add deionized water to prepare a working stock solution of approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely.
Western blotting, ELISA, Tissue extract
At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Store lyophilized protein at –80°C. Lyophilized protein remains stable until the expiry date when stored at –80°C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at –80°C for long term storage. Reconstituted protein can be stored at 4°C for a week.
Quality Control Test
BCA to determine quantity of the protein.
SDS PAGE to determine purity of the protein.
LAL to determine quantity of endotoxin.
All blood samples used for protein preparation were tested and found negative for HBsAg, anti-HCV, HIV Ag/Ab, and syphilis. Since no test can absolutely assure the absence of all infectious agents, this product should be handled as a potential biohazard. This product is intended for research use only.
