Explore the potential of our Recombinant Human CCL8 protein, an essential research tool for immunology-focused investigations. This C-C motif chemokine 8, also known as CCL8, is produced in E. coli and encompasses the 24-99aa expression region of the full-length mature protein. The tag-free protein is supplied in lyophilized powder form, allowing for straightforward reconstitution with sterile water or buffer for a wide range of experimental applications.
Committed to quality and performance, our Recombinant Human CCL8 protein exhibits a purity of >96% as determined by SDS-PAGE and HPLC analysis. Furthermore, endotoxin levels are maintained below 1.0 EU/µg, as determined by the LAL method. The protein demonstrates full biological activity, as determined by a chemotaxis bioassay using human peripheral blood monocytes, with an effective concentration range of 10-100 ng/mL.
Significant research has been conducted to understand the function and relevance of CCL8 (C-C motif chemokine 8) in various biological processes and diseases. CCL8, a member of the CC chemokine family, was first characterized by Proost et al. (1996)[1], who elucidated its role as a chemoattractant for monocytes, eosinophils, and basophils. The involvement of CCL8 in the recruitment of leukocytes during inflammation was further supported by Van Coillie et al. (1999)[2], highlighting its role in immune responses. Menten et al. (2002)[3] explored the relationship between CCL8 and HIV-1 infection, demonstrating that CCL8 serves as a potent inhibitor of the R5 strains of HIV-1, thereby suggesting its potential role in controlling HIV-1 infection. CCL8's association with cancer was demonstrated by Negus et al. (1995)[4], who identified the overexpression of CCL8 in human melanoma cell lines, and it has since been implicated in various cancer types. Furthermore, a study by Bandapalli et al. (2014)[5] revealed the involvement of CCL8 in colorectal cancer progression and its potential as a diagnostic and therapeutic target.
