• Product Overview: Recombinant Cynomolgus/Rhesus TNF protein(Val77-Leu233) was expressed in E. coli.

Specification

• Source: E. coli
• Species: Cynomolgus/Rhesus
• Tag: N/A
• Form: Lyophilized from sterile 50 mM Tris, 50 mM NaCl, pH 8.0.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
