• Cat.No.: ERBB3-209HAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant human ERBB3 (NP_001973.2) precursor extracellular domain (Met 1-Thr 643), fused with a C-terminal polyhistidine tag, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 635
• Form: Lyophilized
• Molecular Mass: The recombinant human ErbB3 protein consists of 635 amino acids after the removal of signal peptide and has a calculated molecular mass of 70.2 kDa. As a result of glycosylation, the recombinant ErbB3 migrates as an approximately 100-110 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 647 via amines
  Excitation = 650 nm
  Emission = 668 nm
• Stability: Samples are stable for up to 12 months from date of receipt at -70 centigrade.
• Storage: Store it under sterile conditions at -20 to -70 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Storage Buffer: Lyophilized from sterile PBS, pH 7.5
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
• Conjugation: Alexa Fluor 647
