Rantes Human

Chemokine (C-C motif) ligand 5 (also CCL5) is a protein which in humans is encoded by the CCL5 gene. It is also known as RANTES (regulated and normal T cell expressed and secreted). It is a chemoattractant towards monocytes, memory T cells (CD4+/CD45RO), basophils, and eosinophils. RANTES also has the capability to inhibit certain strains of HIV-1, HIV-2 and simian immunodeficiency virus (SIV).
Full Name Rantes Human Recombinant (CCL5)
Synonyms Small inducible cytokine A5, CCL5, T-cell-specific RANTES protein, SIS-delta, T cell- specific protein P228, TCP228, chemokine (C-C motif) ligand 5, SISd, SCYA5, RANTES, D17S136E, MGC17164.
Source E. coli
Amino Acid Sequence The sequence of the first five N-terminal amino acids of Rantes was determined and found to be Ser-Pro-Tyr-Ser-Ser.
Molecular Weight Rantes Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 68 amino acids and having a molecular mass of 7.8k Da.
Purity >95% as determined by SDS-PAGE and HPLC
Endotoxin Endotoxin level was found to be ≤ 0.1 ng/µg(1EU/µg) by LAL gel clot method.
Formulation Lyophilized from water containing no additives.
Reconstitution To reconstitute the protein, add sterile water to the lyophilized protein and make a preparation with a concentration ≥0.1mg/ml. The preparation can be diluted into other appropriate buffers if necessary. Be cautious and avoid potential contamination with bacteria and endotoxin
Stability The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity The Rantes activity is determined by the chemoattract of human blood monocytes at a concentration between 1-10ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
Usage LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
