CCL24/Eotaxin-2 蛋白, Mouse

CCL24/Eotaxin-2 Protein, Mouse is a CC chemokine that interacts with the chemokine receptor CCR3 to induce eosinophil chemotaxis and mediate atopic diseases, parasitic infections and systemic diseases, as well as promote cellular transport and regulate inflammatory and fibrotic activities. CCL24/Eotaxin-2 Protein, Mouse is a recombinant mouse CCL24/Eotaxin-2 (V27-V119) protein expressed by E. coli^[1].

CCL24，也称为嗜酸性粒细胞趋化蛋白 2 (eotaxin-2) 和骨髓祖细胞抑制因子 2 (MPIF-2)，是 CC 趋化因子家族的一种小细胞因子，位于人类基因组中的第 7 号染色体上。CCL24 对静息 T 淋巴细胞和嗜酸性粒细胞具有高度趋化活性，对中性粒细胞具有较低趋化活性，但对单核细胞和活化淋巴细胞没有趋化活性。通过与其唯一受体CCR3结合，其中CCR3主要存在于嗜酸性粒细胞上，但也存在于嗜碱性粒细胞、单核细胞、Th2淋巴细胞、上皮细胞和气道平滑肌上。CCL24 主要介导特应性疾病、寄生虫感染和全身性疾病，但也促进细胞运输并调节炎症和纤维化活动^[1][2]。

CCL24 deficiency leads to reduced dermal thickness and infiltration of immune cells into the bronchoalveolar lavage (BAL) fluid and significantly reduced α-SMA expression in a mouse model of bleomycin (BLM)-induced skin fibrosis^[3].

Approximately 12 kDa

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized after extensive dialysis against PBS, pH7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
