Binding Capacity: N/A

Unit Definition: N/A

Molecular Weight: This protein is fused with 6×His tag at the C-terminus, has a calculated MW of 22 kDa. The predicted N-terminus is Ile 22. DTT-reduced Protein migrates as 30-35 kDa due to different glycosylation.

Concentration: N/A

Appearance: Lyophilized

Physical form description: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.

Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.

Background Information: Tumor necrosis factor receptor 1 (TNF-R1) also known as Tumor necrosis factor receptor superfamily member 1A (TNFRSF1A), TNFAR, CD antigen CD120a, belongs to the tumor necrosis factor receptor superfamily. TNF-R1 contains one death domain and four TNFR-Cys repeats. TNF-R1 is the receptor of TNFSF2 / TNF-alpha and homotrimeric TNFSF1 / lymphotoxin - alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. TNF-R1 contributes to the induction of non - cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase. Defects in TNFRSF1A are the cause of familial Hibernian fever (FHF).

Amino acid sequence: N/A

Handling: Centrifuge the vial prior to opening.
