  • Evaluation of CAR expression

    FACS Analysis of Anti-Her2 CAR Expression

     Her2 CAR_T

    5e5 of anti-Her2 CAR-293 cells were stained with 100 μL of 1 μg/mL of Alexa Fluor 647-Labeled Human Her2, His Tag (Cat. No. HE2-HA2H5) and negative control protein respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A). Alexa Fluor 647 signal was used to evaluate the binding activity (QC tested).

  • FACS Analysis of Non-specific binding to PBMCs

     Her2 CAR_T

    5e5 of PBMCs were stained with Alexa Fluor 647-Labeled Human Her2, His Tag (Cat. No. HE2-HA2H5) and anti-CD3 antibody, washed and then analyzed with FACS. FITC signal was used to evaluate the expression of CD3+ T cells in PBMCs, and Alexa Fluor 647 signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).

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 .
