Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human NGF Receptor (HEK293-expressed) (rHuNGFR) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Human NGF Receptor (HEK293-expressed) (rHuNGFR) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background NGFR, also known as p75 neurotrophin receptor (p75NTR) and CD271, is a cell surface receptor that belongs to the tumor necrosis factor receptor superfamily. There are two general classes of neurotrophin receptors: the high-affinity nerve growth factor tyrosine kinase receptors Trk A, B and C (encoded by NTRK1, NTRK2, and NTRK3, respectively) and the low-affinity nerve growth factor receptor NGFR. NGFR has been identified as a marker of cells with tumor-initiating capacity in multiple malignancies, including head and neck squamous cell carcinoma[1]. |
