- Theoretical Molecular Weight
- The protein has a predicted MW of 33.89 kDa. Due to glycosylation, the protein migrates to 42-52 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
CD23 is the low-affinity receptor for immunoglobulin (Ig)E and plays important roles in the regulation of IgE responses. CD23 can be cleaved from cell surfaces to yield a range of soluble CD23 (sCD23) proteins that have pleiotropic cytokine-like activities.
