Storage
It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
  • Until expiry date, -20℃ to -80℃ as lyophilized proteins.
  • 3 months, -20℃ to -80℃ under sterile conditions after reconstitution.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature.

Background

Human epidermal growth factor receptor-3 (ERBB3) is a member of the ERBB receptor tyrosine kinases (RTKs) and is expressed in many malignancies. The importance of ErbB3 receptor tyrosine kinase in cancer progression, primary and acquired drug resistance, has become steadily evident since its discovery in 1989. ErbB3 overexpression in various solid organ malignancies is associated with shorter survival of patients.
