它是在我們嚴(yán)格的質(zhì)量控制體系下生產(chǎn)的，該體系包含一套全面的測(cè)試，包括無菌和內(nèi)毒素測(cè)試。在早期臨床前階段，產(chǎn)品性能經(jīng)過仔細(xì)驗(yàn)證和測(cè)試，以確保其與細(xì)胞培養(yǎng)用途或任何其他應(yīng)用的兼容性。當(dāng)準(zhǔn)備過渡到后期臨床階段時(shí)，我們還提供定制的GMP蛋白質(zhì)服務(wù)，以滿足您的需求。我們將與您合作，根據(jù)您的要求定制和開發(fā)GMP級(jí)產(chǎn)品，該產(chǎn)品也符合細(xì)胞療法細(xì)胞制造中使用的原材料和輔助材料的要求。
蛋白結(jié)構(gòu)（Molecular Characterization）
This protein carries no "tag".
The protein has a calculated MW of 8.4 kDa. The protein migrates as 9 kDa±3 kDa under reducing (R) condition, and 11 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素（Endotoxin）
Less than 0.01 EU per μg by the LAL method.
宿主蛋白殘留（Host Cell Protein）
<0.5 ng/μg of protein tested by ELISA.
宿主核酸殘留（Host Cell DNA）
<0.02 ng/μg of protein tested by qPCR.
無菌（Sterility）
Negative
支原體（Mycoplasma）
Negative.
純度（Purity）
>95% as determined by SDS-PAGE.
>90% as determined by SEC-HPLC.
制劑（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）
Interleukin 8 (IL8 or chemokine (C-X-C motif) ligand 8, CXCL8) is a chemokine produced by macrophages and other cell types such as epithelial cells, airway smooth muscle cells and endothelial cells. There are many receptors on the surface membrane capable of binding IL-8, the most frequently studied types are the G protein-coupled serpentine receptors CXCR1 and CXCR2. Expression and affinity for IL-8 differs between the two receptors (CXCR1 > CXCR2). IL-8(6-77) has a 5-10-fold higher activity on neutrophil activation, IL-8(5-77) has increased activity on neutrophil activation and IL-8(7-77) has a higher affinity to receptors CXCR1 and CXCR2 as compared to IL-8(1-77), respectively.
