Specifications

Recombinant Human MCP-1 also known as Monocyte Chemotactic and Activating Factor (MCAF) is a non-glycosylated, Polypeptide chain containing 76 amino acids and having a molecular mass of 8607 Dalton.
Catalog #M2690-01
SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Gln-Pro-Asp-Ala-Ile.
Dimers and Aggregates 1% as determined by silver-stained SDS-PAGE gel analysis.
Biological ActivityMCP-1 is fully biologically active when compared to standard. The specific activity as determined by the ability of MCP-1 to chemoattract human Monocytes using a concentration of 5-20ng/ml.
Endotoxin 0.1ng/ug (IEU/ug) of rHuMCP-1.
Protein ContentProtein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280nm.
2. Analysis by RP-HPLC, using a standard solution of MCP-1 as a Reference Standard.
ReconstitutionReconstitute the lyophilized rHuMCP-1 in sterile 18M -cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Storage and StabilityLyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
SourceE. coli
Purity95% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified.
Concentration~0.1mg/ml
FormSupplied as a lyophilized powder. No additives.
