Description
RANTES/CCL5 Protein, Rat (His) is a key pro-inflammatory chemokine in the CC chemokine family that interacts with CCR1, CCR3, CCR4, and CCR5 to mediate inflammatory immune responses, viral infections, and tumorigenesis. RANTES/CCL5 Protein, Rat (His) is a recombinant rat RANTES/CCL5 (S25-S92) protein expressed by E. coli with a His tag at the C-terminu[1].
Background
CCL5, also known as RANTES (Regulation of Activation, Expression and Secretion by Normal T Cells), belongs to the CC subfamily of chemokines. The CCL5 gene is located in the q11.2-q12 region of human chromosome 17 and encodes CCL5 a protein with a molecular weight of 8 kDa. CCL5 can be expressed by T cells, monocytes, NK cells, epithelial cells, fibroblasts, and CCL5 can bind to receptors CCR1, CCR3, CCR4 and CCR5, with the highest affinity for CCR5[1]. CCL5 binding to CCR5 leads to phosphorylation of phosphatidylinositol 3-kinase ( PI3K ), and the phosphorylated PI3K further acidifies protein kinase B on serine 473, and the Akt/PKB complex phosphorylates and inactivates the serine/threonine protein kinase GSK-3. In parallel, CCL5 binding to CCR5 induces Bcl2 protein expression, which promotes cell apoptosis. CCL5 can also act as a potential agonist for the G protein-coupled receptor GPR75, which, together with GPR75, may play a role in neuronal survival by activating downstream signaling pathways involving PI3, Akt, and MAP kinases, and in insulin secretion by pancreatic islet cells by activating GPR75[2]. In addition to acting as a chemotactic agent, CCL5 is also a major HIV suppressor produced by CD8+ T cells. It is involved in inflammation maintenance, transplantation, antiviral immunity, tumor development, and many human diseases and disorders such as viral hepatitis or COVID-19[3].

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 500 mM NaCl, 2 mM EDTA, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
