Introduction

趋化因子配体 1 是一种小细胞因子,属于 CXC 趋化因子家族,以前称为 GRO1 致癌基因、中性粒细胞激活蛋白 3 和黑色素瘤生长刺激活性α。 它由人类黑色素瘤细胞分泌,具有促有丝分裂特性,并与黑色素瘤发病机制有关。 CXCL1由巨噬细胞、中性粒细胞和上皮细胞表达,具有中性粒细胞趋化活性。 CXCL1 通过抑制少突胶质细胞前体的迁移在脊髓发育中发挥作用,并参与血管生成、炎症、伤口愈合和肿瘤发生的过程。 这种趋化因子通过趋化因子受体 CXCR2 发出信号来引发其作用。 CXCL1 基因位于人类第 4 号染色体上,位于其他 CXC 趋化因子基因中。

Description

在大肠杆菌中产生的 GRO Alpha Human Recombinant 是一种单一的、非糖基化的多肽链,含有 73 个氨基酸,分子量为 7811 道尔顿。
GRO-alpha 通过专有的色谱技术进行纯化。

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized powder.

Formulation

Lyophilized from a 0.2µm filtered concentrated solution in 20mM PB, pH 7.4, 50mM NaCl.

Solubility

It is recommended to reconstitute the lyophilized CXCL1 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability

Lyophilized GRO-alpha although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

Purity

Greater than 97.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Ser-Val-Ala-Thr.

Biological Activity

Determined by its ability to chemoattract human peripheral blood neutrophils using a concentration range of 10.0-100.0 ng/ml.
