Ectodysplasin A receptor (EDAR), also known as ED1R, is a cell surface receptor of the tumor necrosis factor receptor (TNFR) family. Defects in EDAR are a cause of hypohidrotic ectodermal dysplasia (HED).1 It is characterized by abnormalities in the hair, teeth and sweat glands. EDAR is also the genetic determinant of hair fiber thickness variation among Asian populations.2 EDA has two splice variants, EDA-A1 and EDA-A2, which differ by only two amino acids. Despite this minor difference, EDAR only binds to EDA-A1, whereas EDA-A2 binds to XEDAR. It mediates the activation of NF-κB and JNK and may promote caspase independent cell death.3

State of Matter
Predicted Molecular Mass
The predicted molecular weight of Recombinant Human EDAR is Mr 44.3 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 55-60 kDa.
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.
Storage and Stability
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.
