DARC (Duffy Antigen/Chemokine Receptor, Duffy Antigen/Chemokine Receptor, Fy Glycoprotein D, GpFy, Cell Adhesion Molecule 3, CADM3, Plasmodium Vivax Receptor,CCBP1, CD234, CD234 antigen, Dfy, GpFy, Plasmodium vivax receptor) (Control Peptide)

HRAELSPSTENSSQLDFED-C, from the N-Terminus of human DARC.\nControl peptide corresponding to polyclonal antibody, Catalog#D1065-50J, goat x human.\n\nDARC, also known as the Duffy antigen/chemokine receptor, is a seven-transmembrane protein homologous to the classical chemokine G-protein coupled receptors (GPCRs) with the exception of the motif required for G protein coupling. DARC can bind with high affinity several chemokines without transducing any signal, suggesting it may modulate the signals normally induced by these chemokines. Recently, DARC was found to interact with KAI1, a four transmembrane protein recently identified as a tumor metastasis suppressor protein. It is thought that tumor cells dislodged from the primary tumor and expressing KAI1 interact with DARC proteins expressed on vascular cells, transmitting a senescent signal to the tumor cells, while tumor cells that have lost KAI1 expression can proliferate and potentially give rise to metastases. At least three isoforms of DARC are known to exist.\n\nApplications:\nSuitable for use in ELISA. Other applications have not been tested. \n\nRecommended Dilutions:\nOptimal dilutions to be determined by the researcher\n\nPositive Control:\nHuman kidney and human liver lysates\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 monthsat -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.\n\nPeptide Blocking (see corresponding antibody D1065-50J):\nAntibodies are typically supplied at 0.5mg/ml and peptides as a 100ul pellet. When peptides are reconstituted in 200ul water, the concentration would be also 0.5mg/ml. To start, the best ratio would be 1:1 (which means molar excess of peptides relative to antibodies when identical volumes are mixed). Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature. It is best is to have two identical blots, to be incubated with equal amount of antibodies, but one with the antibodies pre-adsorbed to the peptide for 20min. Then incubate and develop the two blots in parallel.
