原理特点

特异性识别ERK1/ERK2蛋白的单一表位。ERK1/2是Ras-Raf-MEK通路的下游核心激酶，将胞外生长因子信号传递入核，磷酸化多种转录因子，驱动细胞增殖、分化和存活。该单抗以高亲和力和低背景，用于精准检测ERK总蛋白水平，是细胞信号转导研究的基石试剂。

靶点背景

MAPK1 (ERK2)、MAPK2 (ERK1) 属于经典 ERK 丝裂原活化蛋白激酶通路，接收生长因子、细胞因子信号，逐级磷酸化激活。

活化 ERK1/2 入核调控 Cyclin、c-Myc 等转录因子，主导细胞增殖、迁移、分化、存活；通路异常高激活驱动肿瘤增殖、侵袭、耐药。

广泛应用肿瘤、炎症、心血管、干细胞方向，可检测总 ERK1/2 蛋白表达水平。

抗体的鉴定

1）抗体的效价鉴定：鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。

2）抗体的特异性鉴定：抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。

3）抗体的亲和力：是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。
