Source / Purification

Recombinant human CCL3 (hCCL3) Ala27-Ala92 (Accession #NP_002974) was produced in E. coli at Cell Signaling Technology.

CST在大肠杆菌细胞中表达重组的人CCL3 (hCCL3) Ala27-Ala92 (Accession #NP_002974)蛋白。

Molecular Characterization

Recombinant hCCL3 does not have a Met on the amino terminus and has a calculated MW of 7445. DTT-reduced and non-reduced protein migrate as 8 kDa polypeptides. The expected amino-terminal ADTPT of recombinant hCCL3 was verified by amino acid sequencing.



>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hCCL3. All lots are greater than 98% pure.

6 μg 还原 (+) 和 非还原的(-) 重组hCCL通过SDS-PAGE检测,纯度大于98%,所有批次的纯度均高于98%。


The activity of hCCL3 was determined using a THP-1 cell migration assay. The ED50 of each lot is between 0.5-1.2 ng/ml.

重组蛋白hCCL3的生物活性是通过THP-1细胞的迁移实验确定的。每个批次的ED50在0.5-1.2 ng/ml之间。

The purity of recombinant hCCL3 was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant hCCL3 and staining overnight with Coomassie Blue.重组hCCL3蛋白的纯度通过SDS-PAGE 来确定。6 µg 经还原(+)和未经过还原(-) 的重组hCCL3蛋白跑SDS胶并用考马斯亮蓝染色过夜。



hCCL3-induced migration of THP-1 cells was asssessd. THP-1 cells were incubated in a 96-well transwell plate with increasing concentrations of hCCL3 in the bottom chamber. After 2 hr, the number of THP-1 cells that migrated to the bottom chamber of the transwell was quantified by measuring DNA content using a fluorescent dye.hCCL3诱导THP-1细胞迁移的实验。用递增浓度的hCCL3 在96孔板的底层小室中培养THP-1细胞,2小时后迁移出底层小室的细胞的DNA含量用荧光染料测定。

CCL3, also know as MIP-1-α, or LD78α, is an 8 kDa member of the C-C family of chemokines, which play key roles in immune surveillance, inflammation, and infection (1). CCL3 shares 68% amino acid identity with CCL4 (MIP-1-β) and 94% amino acid identity with LD78β (1). CCL3 is produced by activated monocytes, activated macrophages, NK cells, and T cells among others (1). There are two receptors for CCL3: CCR1 and CCR5 (1). CCL3 inhibits R5 HIV-1 infection by competing with the virus for its co-receptor, CCR5 (1). CCL3 polymorphisms are associated with risk for the development of rheumatoid arthritis and ulcerative colitis (2,3).

CCL3, 也叫做 MIP-1-α或 LD78α, 是定位于膜上的8 kDa C-C家族趋化因子,它在免疫监控、炎症和感染等过程发挥了重要的作用(1)。CCL3与CCL4 (MIP-1-β)有68%氨基酸相似度与LD78β具有94%的氨基酸相似度(1)。CCL3的产生是通过激活的单核细胞、激活的巨噬体、NK细胞、T细胞以及其他的细胞类型(1)。CCL3有两个受体: CCR1和CCR5 (1)。CCL3通过与R5 HIV-1病毒竞争其共受体 CCR5 而抑制病毒的感染(1)。CCL3的多态性与类风湿性关节炎和溃疡性结肠炎的发展有关(2,3)。
