Specificity / Sensitivity

Ki-67 (D3B5) Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total Ki-67 protein.Ki-67 (D3B5) Rabbit mAb (偶联Alexa Fluor® 488)可以识别内源性总的Ki-67蛋白。

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human Ki-67 protein.单克隆抗体由合成肽段免疫动物产生,该肽段与人Ki-67蛋白的氨基端一致。

Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric and immunofluorescent analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Ki-67 (D3B5) Rabbit mAb #9129.Cell Signaling Technology公司抗体偶联Alexa Fluor® 488荧光素染料并经人类细胞直接流式细胞仪免疫荧光分析内部测试。抗体预期和未偶联Alexa Fluor® 488的Ki-67 (D3B5)Rabbit mAb #9129显示同样的物种交叉反应.

Background

Ki-67, named after the location where it was discovered (Kiel University, Germany), is a nuclear nonhistone protein (1) that is universally expressed among proliferating cells and absent in quiescent cells (2). Ki-67 detects proliferating cells in G1, S, G2, and mitosis, but not in the G0 resting phase. Research studies have shown that high levels of Ki-67 are associated with poorer breast cancer survival (3). Research studies have explored the use of Ki-67, along with other markers, as potential prognostic or predictive markers in breast cancer and other malignant diseases (4).Ki-67,以其发现地命名(Kiel大学,德国),作为一个细胞核非组蛋白(1)通常在增殖的细胞中表达并且在休眠细胞中不表达(2)。Ki-67会让增殖细胞停滞在G1,S,G2和有丝分裂期,但是不会停滞在G0期。研究显示高表达的Ki-67与低乳腺癌存活率相关(3)。研究已经将Ki-67与其他的标记,作为乳腺癌和其他恶性疾病中的潜在的预后和预测标记(4)。
