Name :
Serum Albumin Protein
Description :
Albumins are multifunctional proteins present in the blood serum of animals. They can bind and transport a wide variety of ligands which they accommodate due to their conformational flexibility. Serum albumins are highly conserved both in amino acid sequence and three-dimensional structure. Several mammalian and avian serum albumins (SAs) are also allergens. Sensitization to one of the SAs coupled with the high degree of conservation between SAs may result in cross-reactive antibodies in allergic individuals.
Species :
Mouse
Uniprotkb :
HEK293
Tag :

Albumin, PRO0883, PRO0903, ANALBA, Serum albumin, PRO1341, FDAH, ALB
Construction :
Recombinant Mouse Serum Albumin Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Glu25-Ala608.[Accession |P07724]
Protein Purity :
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight :
The protein has a predicted MW of 70.19 kDa same as Tris-Bis PAGE result.
Endotoxin :
Less than 1EU per ug by the LAL method.
Formulatione :
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.
Stability & Storage :
-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state 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.
Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
