Cetuximab
CAS No. : 205923-56-4
MCE 国际站:Cetuximab
产品活性:Cetuximab (C225) 是一种人源 IgG1 单克隆抗体,能够抑制 EGFR,SPR 方法测得 Cetuximab 对 EGFR 的 Kd 值为 0.201 nM;Cetuximab 具有高效的抗肿瘤作用。
研究领域:JAK/STAT Signaling | Protein Tyrosine Kinase/RTK
作用靶点:EGFR
In Vitro: Cetuximab (C225) is a monoclonal antibody that inhibits epidermal growth factor receptor (EGFR), with a Kd of 0.201 nM for soluble EGFR by SPR. Cetuximab also exhibits a Kd of 0.147 nM for EGFR in fixed A431 cells by ELISA.
Cetuximab (C225; 30 nM) time-dependently inhibits the proliferation of SCC-1, SCC-11B, SCC-38, and SCC-13Y cells after treatment for 8 d. Cetuximab (30 nM) causes G0/G1 arrest, induces apoptosis, and reduces Rb, p27KIP1, Bcl-2, and Bax expression in SCC-13Y cells. Cetuximab (30 nM) also enhances radiosensitivity and increases radiation-induced apoptosis in SCC-13Y cells.
In Vivo: Cetuximab (1 mg/injection) has effect on the tumour volume but the effect is more pronounced on UT-SCC-14 xenografts. In UT-SCC-14 xenografts, Cetuximab significantly reduces the expression of EGFR, pEGFR and Ki67. Cetuximab significantly decreases the expression in the MCT1 and GLUT1 cells but differences are more pronounced in UT-SCC-14 xenografts.
