  • Molecular Characterization
    Online(Thr 23 - Thr 653) AAH53078.1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 70.6 kDa. The protein migrates as 80-95 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE

  • Background
    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 .

ACROBiosystems治疗性抗体的功效不仅取决于Fab片段及其与靶抗原的结合活性,还取决于Fc片段及其与关键Fc受体的相互作用。Fc片段对FcRn的结合亲和力(FCGRT&B2M)将预测抗体的半衰期,而Fc片段与FcγRIIIa(CD16a)之间的结合亲和力将影响抗体引发ADCC的能力(抗体依赖性细胞介导的细胞毒性)。因此,必须在抗体工程化过程中针对一组受体测试候选人。ACROBiosystems提供了完整的重组Fc受体蛋白集合,包括它们的常见变体,以帮助您加快mAb的开发。
