Recombinant Rat GDNF Rα1

Glial Cell-Line Derived Neurotrophic Factor Receptor Alpha 1 (GDNFR-alpha 1), also known as GFRA1, is a novel glycosylphosphatidylinositol-linked cell surface receptor for glial cell line-derived neurotrophic factor (GDNF)¹ that is expressed by Spermatogonial stem cells (SSCs).² GDNF has been known for many years to protect and restore dopamine neurons of the substantia nigra (SN) in lesion models of parkinsonism.³

Lyophilized

The predicted molecular weight of Recombinant Rat GDNF Rα1 is Mr 74 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 95 kDa.

74

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
