Sequence: | Ala 118-Cys 281 |
Accession: | Q61646 |
Storage: | Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
Shipping: | This product is provided as lyophilized powder which is shipped with ice packs. |
Formulation: | Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |
Reconstitution: | Please refer to the printed manual for detailed information. |
Background: | Haptoglobin is a 45‑48 kDa acute phase glycoprotein that is a naturally inactive member of the peptidase S1 family of serine proteases. It is secreted by multiple cell types and protects tissues from hemoglobin-mediated oxidative damage. Mature mouse (pro)haptoglobin is 329 amino acids (aa) in length. Proteolytic cleavage between Arg102-Ile103 creates disulfide-linked alpha - and beta -chains, which subsequently homodimerize through alpha -chain linkages to create a tetramer. Circulating haptoglobin is 70% tetramer and 30% unprocessed (pro)haptoglobin. |
