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 K_d 值为 0.201 nM；Cetuximab 具有高效的抗肿瘤作用。

研究领域：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 K_d of 0.201 nM for soluble EGFR by SPR. Cetuximab also exhibits a K_d 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, p27^KIP1, 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 treatment significantly reduces the expression of EGFR, pEGFR and Ki67. The MCT1 and GLUT1 expression is significantly decreased in the Cetuximab-treated groups of both cell lines but differences are more pronounced in UT-SCC-14 xenografts.
