Introduction

Interleukin-8 is a chemokine produced by macrophages and other cell types such as epithelial cells. It is also synthesized by endothelial cells, which store IL-8 in their storage vesicles, the Weibel-Palade bodies. When first encountering an antigen, the primary cells to encounter it are the macrophages who phagocytose the particle. Upon processing, they release chemokines to signal other immune cells to come in to the site of inflammation. IL-8 is one such chemokine. It serves as a chemical signal that attracts neutrophils at the site of inflammation, and therefore is also known as Neutrophil Chemotactic Factor.
白细胞介素 8 是一种由巨噬细胞和其他细胞类型(如上皮细胞)产生的趋化因子。 它也由内皮细胞合成,内皮细胞将 IL-8 储存在它们的储存囊泡 Weibel-Palade 体中。 当第一次遇到抗原时,遇到它的原代细胞是吞噬颗粒的巨噬细胞。 在处理后,它们会释放趋化因子以向其他免疫细胞发出信号,使其进入炎症部位。 IL-8 就是这样一种趋化因子。 它作为一种化学信号,在炎症部位吸引中性粒细胞,因此也称为中性粒细胞趋化因子。

Description

Interleukin-8 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 72 amino acids and having a molecular mass of 8452 Dalton.
The IL-8 is purified by proprietary chromatographic techniques.
在大肠杆菌中产生的白细胞介素 8 人重组体是一种单一的、非糖基化的多肽链,包含 72 个氨基酸,分子量为 8452 道尔顿。
IL-8 通过专有的色谱技术进行纯化。

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized powder.

Formulation

The IL-8 was lyophilized from a concentrated solution in water containing no additives.

Solubility

It is recommended to reconstitute the lyophilized Interleukin-8 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability

Lyophilized Interleukin-8 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL8 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 98.0% 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 Ser-Ala-Lys-Glu-Leu.

Biological Activity

Specific Activity of IL8 in chemotaxis of donor PBL neutrophils, threshold concentration corresponding to 10-100 ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.

Usage

Prospec’s products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
