NECTIN4

脊髓灰質(zhì)炎病毒受體4(Nectin-4)屬于免疫球蛋白超家族(IgSF),是一類新發(fā)現(xiàn)的細(xì)胞黏附分子。NECTIN4作為一種I型膜蛋白,在正常的胚胎和胎兒組織中含量很高,成年后下降,在健康組織中的分布非常有限。然而,Nectin-4蛋白在尿路上皮癌、乳腺癌、膀胱癌、卵巢癌、胃癌、肝細(xì)胞癌和胰腺癌等組織中都具有特異性的高表達(dá),其主要通過激活PI3K/Akt途徑促進(jìn)腫瘤細(xì)胞增殖、分化、遷移、侵襲等。目前,已上市的Nectin-4 ADC藥物Padcev(Enfortumab vedotin)已展示出與免疫檢查點(diǎn)抑制劑聯(lián)用的優(yōu)異臨床潛力,用于局部晚期或轉(zhuǎn)移性尿路上皮癌成人患者。未來,靶向Nectin-4的抗體-藥物偶聯(lián)物有望進(jìn)一步將適應(yīng)癥拓寬至乳腺癌和胃癌等其它惡性腫瘤。

Recombinant Human NECTIN4 活性蛋白實(shí)驗(yàn)驗(yàn)證數(shù)據(jù)

High Purity Validated by SDS-PAGE

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Excellent Bioactivity Validated by Functional ELISA

Measured by its binding ability in a functional ELISA. Immobilized NECTIN4 at 2 μg/ml can bind anti-NECTIN4 antibody(CSB-RA822274A0HU)(enfortumab vedotin-like), the EC50 is 0.6029-0.7837 ng/mL.
