Product Description

Recombinant Human TNF alpha Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Val77-Leu233.

Product Properties

• Molecular Weight: The protein has a predicted MW of 20.3 kDa. Due to glycosylation, the protein migrates to 21-25 kDa based on Bis-Tris PAGE result.

• Buffer: Lyophilized from 0.22µm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Expression System: HEK293
• Purity: > 90% as determined by Bis-Tris PAGE,> 95% as determined by HPLC
• Form: Lyophilized
• Sequence: Val77-Leu233
• Target: TNF alpha
