Name : Human Her4/ErbB4 Protein

Product Source :
Recombinant Human Her4/ErbB4 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Gln26-Pro651.[Accession | Q15303-1]

Molecular Weight :
The protein has a predicted MW of 96.6 kDa. Due to glycosylation, the protein migrates to 100-120 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Human Her4/ErbB4 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human Her4/ErbB4 is greater than 95% as determined by SEC-HPLC.

Background :
ErbB4, a member of the EGF receptor family, plays a variety of roles in physiological and pathological states. Genetic studies have indicated a link between ErbB4 and type 2 diabetes and obesity. ErbB4 may play an important role in glucose homeostasis and lipogenesis. ErbB4 deficiency-related obesity and adipose tissue inflammation may contribute to the development of MetS.

Synonyms :
p180erbB4; 4ICD; E4ICD; HER4; ErbB4; MGC138404; ALS19
