General description

Tumor necrosis factor receptor superfamily member 16 (UniProt P07174; also known as CD271, Gp80-LNGFR, Low-affinity nerve growth factor receptor, Low affinity neurotrophin receptor p75NTR, NGF receptor, p75 ICD) is encoded by the Ngfr (also known as Tnfrsf16) gene (Gene ID 24596) in rat species. p75NTR is a single pass type I membrane protein that can bind to NGF, BDNF, NT-3 and NT-4 and mediate neuronal cell survival and death. NGF and p75NTR are considered as important mediators of pain. Levels of p75NTR are shown to increase following nerve injury and its functional inhibition suppresses injury-induced neuropathic pain in rats. In non-neural cells, p75NTR expression correlates with differentiation and dedifferentiation processes and it is transient expression is observed during development of kidney, lungs, ovary, and muscle. Down-regulation of p75NTR is considered to be important during myogenic differentiation and muscle repair. Ref.: Fukui, Y. et al. (2010). J. Orthoped. Res. 28, 279-283. Deponti, D. et al. (2009).

Immunogen

GST-tagged recombinant rat p75NTR ICD fragment.

Other Notes

Concentration: Please refer to lot specific datasheet.

Physical form

Unpurified.

Rabbit polyclonal antibody serum with 0.05% sodium azide.

Quality

Evaluated by Western Blotting in mouse retina tissue lysate.

Western Blotting Analysis: A 1:5,000 dilution of this antiserum detected the ~25 kDa p75NTR (neurotrophin receptor) ICD fragment in 10 µg of mouse retina tissue lysate.

Specificity

This antiserum detected the ~75 kDa full-length p75NTR (neurotrophin receptor) as well as the ~30 kDa CTF and the ~25 kDa ICD cleavage fragments by immunoprecipitation and Western blotting (Kenchappa, R.S., et al. (2006). Neuron. 50(2):219-232).

Storage and Stability

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
