Native Human alpha 1 microglobulin is native human Alpha-1-Microglobulin, a secreted peptide thought to play a role in the regulation of inflammatory processes.

This product runs at approximately 27 kDa under reducing conditions and as a dimer at approximately 54 kDa under non-reducing conditions.

Target Species
Product Form
Purified protein from the urine of patients with chronic renal tubular proteinuria - lyophilized
Reconstitute with 1.0ml sterile phosphate buffered saline (PBS).
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Purified Alpha 1 Microglobulin prepared by a combination of ion exchange, affinity and size exclusion chromatography.
Preservative Stabilisers
None present
>96% by SDS PAGE
Approx. Protein Concentrations
Total protein concentration 1.0mg/ml after reconstitution.
For research purposes only
Guaranteed until date of expiry. Please see product label.

Prior to reconstitution store at +4oC.
After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.
