Protein Length
His17-Leu531
Expression System
HEK293
Theoretical Molecular Weight
The protein has a predicted MW of 82.47 kDa. Due to glycosylation, the protein migrates to 130-170 kDa based on Bis-Tris PAGE result.
Purity
> 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin
Less than 0.1 EU per μg by the LAL method.
Buffer / Formulation
Lyophilized from 0.22 μm filtered solution in PBS, 100mM L-Arginine (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

Absence of the CD42 complex leads to the Bernard-Soulier syndrome (BSS), which is a bleeding disorder characterized by thrombocytopenia and giant platelets. So far, mutations have been found in the genes encoding CD42a, CD42b and CD42c in patients with BSS**.
