Recombinant Human ERBB3 Protein, ECD, Tag Free, Biotinylated

• Cat.No.: ERBB3-114H
• Product Overview: Recombinant human HER3 (ERBB3) protein was developed from CHO cells.

Specification

• Species: Human
• Source: CHO
• Tag: Non
• Protein Length: ECD
• Description: This gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.
• Conjugation/Label: Biotin
• Form: Lyophilised
• Endotoxin: Endotoxin level was found to be less than 0.1 ng/μg (1 EU/μg).
• Applications: ELISA, WB
• Notes: FOR RESEARCH USE ONLY (RUO).
• Storage: The lyophilized protein is stable for at least 1 year from date of receipt at -20 centigrade. Upon reconstitution, this cytokine can be stored in working aliquots at 2 to 8 centigrade for one month, or at -20 centigrade for six months, with a carrier protein without detectable loss
• Storage Buffer: Lyophilised from 0.2 μm filtered PBS pH 7.4.
• Reconstitution: Upon receipt a quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
