Product Details
- Molecular Aliases
- Albumin; ALB; Serum albumin; ANALBA; FDAH; PRO0883; PRO0903; PRO1341
- Protein Length
- Asp25-Leu609
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 69.4 kDa. Due to glycosylation, the protein migrates to 69-70 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background
Human serum albumin (HSA), the most prominent protein in plasma, binds different classes of ligands at multiple sites. HSA provides a depot for many compounds, affects pharmacokinetics of many drugs, holds some ligands in a strained orientation providing their metabolic modification, renders potential toxins harmless transporting them to disposal sites, accounts for most of the antioxidant capacity of human serum, and acts as a NO-carrier.
