Macrophage, Monocyte Chemotactic Protein 3, Recombinant, Mouse (MCP-3, MARC)

Recombinant Murine MCP-3 is a non-glycosylated, Polypeptide chain containing 74 amino acids and having a molecular mass of 8510 Dalton.\n\nSequence:\nThe sequence of the first five N-terminal amino acids was determined and was found to be Gln-Pro-Ala-Gly-Pro.\n\nDimers and Aggregates:\n(same/less than) 1% as determined by silver-stained SDS-PAGE gel analysis.\n\nBiological Activity:\nMurine MCP-3 is fully biologically active when compared to standard. The specific activity as determined by the ability of Murine MCP-3 to chemoattract Balb/C mouse spleen MNCs at 10-100ng/ml.\n\nEndotoxin:\n(same/less than) 0.1ng/ug (IEU/ug) of Murine Monocyte Chemotactic Protein-3.\n\nProtein Content:\nProtein quantitation was carried out by two independent methods: \n1. UV spectroscopy at 280nm. \n2. Analysis by RP-HPLC, using a calibrated solution of Murine MCP-3 as a Reference Standard.\n\nReconstitution:\nReconstitute the lyophilized MCP-3 in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.\n\nStorage and Stability:\nLyophilized powder may be stored at 4 degrees C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
