Uses
RANTES human has been used in following studies:
- In transmigration experiments to determine whether LFA-1 cross-linking could affect peripheral blood T lymphocytes (PBTL) migration in response to the chemokine RANTES.
- Luminol-dependent chemiluminescence assay to determine the effect of RANTES on reactive oxygen species (ROS) production by eosinophils.
Biological Activity
Regulated on activation, normal T cell expressed and secreted (RANTES) is a chemoattractant towards monocytes, dendritic cells (DCs), memory T cells (CD4+/CD45RO), basophils, and eosinophils. The encoded chemokine protein functions as a ligand for CCR1, CCR3, and CCR5.1 RANTES inhibits the action of R5 strains of HIV-1 via blocking CCR5 receptor. The In1.1C variant of RANTES gene is linked with susceptibility to HIV-1 infection and disease progression. Hence, this can be used as a potent biomarker to determine the prognosis of HIV-1 infection.
Description

The MCP2 is purified by proprietary chromatographic techniques.
Background
Regulated upon Activation, Normal T-cell Expressed, and Secreted or RANTES is an 8 kDa protein classified as a chemotactic cytokine or chemokine. Rantes has recently been renamed CCL5. RANTES is chemotactic for T cells, eosinophils and basophils and plays an active role in recruiting leukocytes into inflammatory sites. With the help of particular cytokines (i.e. IL-2 and IFN-g) that are released by T cells, RANTES also induces the proliferation and activation of certain natural killer (NK) cells to form CHAK (CC-Chemokine-activated killer) cells. Rantes is also an HIV-suppressive factor released from CD8+ T cells. The Rantes chemokine has been localized to chromosome 17 in humans.
