TNFRSF1A / TNFR1 Protein QC Testing

纯度: > 95 % as determined by SDS-PAGE SDS-PAGE
内**: < 1.0 EU per μg of the protein as determined by the LAL method
稳定性: Samples are stable for up to twelve months from date of receipt at -70℃
预测N端: Ile 22
分子量: 
The recombinant rat TNFRSF1A comprises 201 amino acids and predicts a molecular mass of 22.3 kDa. The apparent molecular mass of  the recombinant protein is approximately 33-38 kDa in SDS-PAGE under reducing conditions due to glycosylation.
缓冲液: Lyophilized from sterile PBS, pH 7.4.
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Please contact us for any concerns or special requirements.

TNFRSF1A / TNFR1 Protein Usage Guide

储存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

TNFRSF1A / TNFR1蛋白背景综述

Tumor necrosis factor receptor superfamily, member 1A (TNFRSF1A), also known as TNFRI, TNF R-p55/p60, and CD120a, is a type I transmembrane protein widely expressed and is present on the cell surface as a trimer of 55 kDa subunits. Human TNFRSF1A/TNFRI is a 455 aa protein that contains a 21 aa signal sequence, a 190 aa ECD with a PLAD domain which mediates constitutive trimer formation followed by four TNF-α trimer-binding cysteine-rich domains (CRDs), a 23 aa transmembrane domain, and a 221 aa cytoplasmic sequence that contains a neutral sphingomyelinase activation domain and a death domain. TNFRSF1A/TNFRI serves as a receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor, and the resulting death-inducing signaling complex (DISC) initiates the subsequent cascade of caspases mediating apoptosis. TNFRSF1A/TNFRI can also activate the transcription factor NF-kB, and functions as a regulator of inflammation. Germline mutations of the extracellular domains of TNF RI are found to be associated with the human genetic disorder called periodic fever syndrome.
