Application

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.

Biochem/physiol Actions

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.

General description

Regulated on activation, normal T cell expressed and secreted (RANTES) also known as C-C motif chemokine ligand 5 (CCL5) is encoded by the gene mapped to human chromosome 17. RANTES belongs to intercrine or chemokine family of proinflammatory basic polypeptides and is expressed by various hematopoietic and non-hematopoietic cell types involved in homing and migration of effector and memory T cells during acute infections. Recombinant human RANTES is a 7.8kDa protein containing 68 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
