    产品概述

    重组大鼠粒细胞-巨噬细胞集落刺激因子(GM-CSF)蛋白(货号:PRP1242)是一种通过大肠杆菌表达系统生产的重组蛋白,基于大鼠GM-CSF序列(蛋白质ID:P48750),用于细胞培养研究中快速、高效地诱导细胞增殖和分化。该蛋白通过精确表达氨基酸序列(Ala18-Lys144),提供高纯度和生物活性,适用于免疫相关实验。

    GM-CSF(粒细胞-巨噬细胞集落刺激因子)是一种关键细胞因子,被证明可诱导髓样树突状细胞(DCs)的分化,从而促进同源T细胞中T辅助型1(Th1)免疫反应的发展。其活性形式在细胞外表现为同二聚体,编码基因(基因ID:12981)定位于染色体5q31区域,该区域与5q综合征和急性髓性白血病相关。作为免疫/炎症级联反应的核心组分,GM-CSF促进Th1偏向性免疫、血管生成、过敏性炎症和自身免疫,因此被广泛视为治疗靶点,并已用于多种疾病过程的临床管理。

    本产品主要应用于细胞培养领域,特别适用于免疫学研究、细胞增殖与分化实验、以及炎症相关疾病模型的构建。其在体外实验中支持科研人员探索Th1免疫反应、血管生成机制和自身免疫疾病靶点,是细胞因子研究中的核心工具。
