Purification/Conjugué: Cette ErbB2/Her2 protéine est marqué à la His tag,Biotin.

Marque: MABSol®,UltraLys

Séquence: AA 23-652

Specificité: The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Attributs du produit: This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 70.2 kDa. The protein migrates as 110-115 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.

Pureté: >95 % as determined by reduced SDS-PAGE.

niveau d'endotoxine: Less than 1.0 EU per μg by the LAL method.

Information d'application

Commentaires:

A chemically labeled biotinylated protein with ultra sensitivity.
The product is produced using a chemical labeling approach. The primary amines in the side chains of lysine residues and the N-terminus of protein are conjugated with biotins.
Chemical labeling usually results in multiple biotin attachment on a single protein molecule, which could potentially lead to higher detection sensitivity.

Sujet: Human Epidermal growth factor Receptor 2 (HER2) is also called ERBB2, HER-2,HER-2 /neu, NEU, NGL,TKR1 and c-erb B2,and is a protein giving higher aggressiveness in breast cancers. It is a member of the ErbB protein family, more commonly known as the epidermal growth factor receptor family. HER2 is a cell membrane surface-bound receptor tyrosine kinase and is normally involved in the signal transduction pathways leading to cell growth and differentiation. HER2 is thought to be an orphan receptor, with none of the EGF family of ligands able to activate it. Approximately 30 % of breast cancers have an amplification of the HER2 gene or overexpression of its protein product. Overexpression of this receptor in breast cancer is associated with increased disease recurrence and worse prognosis. HER2 appears to play roles in development, cancer, communication at the neuromuscular junction and regulation of cell growth and differentiation .
