    • IHC image of CSB-RA553053A0HU diluted at 1:100 and staining in paraffin-embedded human liver tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

  • 产品描述：
    KLKB1重组单克隆抗体（产品编号：CSB-RA553053A0HU）是针对人血浆激肽释放酶B1（Kallikrein B1）设计的高特异性科研工具。KLKB1是丝氨酸蛋白酶家族成员，通过激活激肽原生成缓激肽，参与凝血级联反应、炎症调控及血管张力调节等重要生理过程。本抗体经ELISA和免疫组化（IHC）等多平台严格验证，在IHC应用中表现出优异的组织定位能力，推荐使用1:50至1:200的稀释比例可获得清晰的靶蛋白信号，且不同实验批次间具有高度一致性。该产品适用于探索KLKB1在凝血机制、病理状态下的血管通透性变化或炎症相关疾病模型中的表达特征，支持研究者通过免疫组化技术对石蜡包埋组织切片中的蛋白分布进行可视化分析，或通过ELISA定量检测体外样本中的蛋白水平变化。其高亲和力和低交叉反应性设计为功能研究和信号通路解析提供了可靠保障。

  • 功能：
    The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin.
