RANTES
RANTES (or Regulated upon Activation, Normal T-cell Expressed and Secreted), also known as CCL5 (Chemokine (CC chemokine ligand 5), is a protein classified as a chemotactic cytokine or chemokine.
Chemokines are small soluble proteins that act as molecular signals to induce cellular migration during inflammation.
RANTES is a member of the CC chemokine family and is involved in immunoregulatory and inflammatory processes.
RANTES is expressed in a lot of immune cells and acts as a potent chemoattractant for T-cells, basophils, eosinophils, monocytes and other cell types by playing a major role in recruiting leukocytes into inflammatory sites and to activate them. RANTES also induces proliferation and activation of certain natural killer cells.
RANTES synthesis is induced by TNF-alpha and IL-1 alpha, interacts with CCR3, CCR1 and CCR5 and activates some G-protein coupled receptors.
Many of the biological activities of RANTES (Ca2+ influx, chemotactic response, basophil activation, T-cell signaling) are observed between 40 and 8000 ng/mL.ACE2 biotinylated peptide library

Heavy calcitonin peptide – Stable Isotope PeptideHuman Calcitonin (hCT) is a 32-amino acid hormone peptide belonging to the Calcitonin/Calcitonin-gene related peptide (CGRP) family, that also comprises amylin, adrenomedullin (AM) and adrenomedullin2/intermedin (AM2/IMD). Calcitonin is characterized by a N-terminal disulfide bond that forms a 7 amino acid ring structure, a region with a α-helix tendency and an amidated C-terminus1.Calcitonin peptide is produced by C cells of the thyroid gland and binds preferentially to the G-protein coupled receptor, calcitonin receptor (CTR)1. Calcitonin receptor signals through activated Gs protein and the production of cAMP second messenger molecules by adenylyl cyclase1. The dissociation constant (Kd) of calcitonin receptors expressed by a human ovarian small cell carcinoma line is approximately 4.6 nM for human Calcitonin2.Calcitonin is involved in the homeostasis of calcium and phosphorus, and the regulation of bone dynamics. At the basal state, calcitonin secretion reduces plasma calcium and phosphorus levels, and promote bone formation. In Calca -/- mice, a murin particle-induced osteolysis model, Calcitonin peptide has been used as a test compound for studying the effects of calcitonin deficiency. It has been shown that artificial calcitonin subsitution inhibits bone resorption by reducing the formation of osteoclasts and thereby the resulting osteolytic reaction3. The Hypocalcemic Human calcitonin was also used as a positive control to monitor changes in serum calcium levels in HHD transgenic mice vaccinated with Parathyroid hormone-related protein (PTH-rP)-derived peptides in the context of anti-cancer immunotherapy study4. Moreover, it has been reported that calcitonin peptide is a potent stimulator of uncapacitated mouse spermatozoa by regulating a specific isoform of adenylyl cyclase and the production of cAMP, which plays a pivotal role in mammalian sperm function5.sb-PEPTIDE provides stable isotope labeled calcitonin peptide. This peptide has been quantified accurately using amino acid analysis.Biotin-FluM1 (58-66)

The GILGFVFTL epitope is highly conserved in Influenza A virus strains at a rate of 93% for 69 strains tested. Human Influenza epitopes may bind MHC molecules and then may be recognized by CD8+ cytotoxic T cells. Applications of FluM1 (58-66): FluM1 (58-66) is used to stimulate CTL responses in peripheral blood mononuclear cells (PBMCs). Then, ELISPOT assay is used to quantify peptide epitope specificity and IFN-γ releasing effector cells. FluM1 (58-66) has shown CTL responses qualified of immunodominant with restriction by HLA-A*02:01. It has also been detected CTL responses when FluM1 (58-66) is restricted by all HLA-C. Therefore, FluM1 (58-66) may help to understand the reaction of immune system against Influenza virus of each populations having different HLA type. FluM1 (58-66) has indeed prompted research to develop T-cell vaccine strategies capable of inducing specific CTL responses in patients upon immunization with Influenza M1 antigenic epitope. MVA-NP+M1 vaccine use GILGFVFTL epitope and is tested in clinical trial. Potential cross-reactivity with HIV-1 p17 Gag (77-85): Moreover, FluM1 (58-66) share similarities with HIV-1 p17 Gag (77-85) which can potentially show a cross-reactivity between these epitopes.
