Recombinant Murine JE(MCP-1) is a single,non-glycosylated, polypeptide chain containing 125 amino acids and having a molecular mass of 13803 Dalton.

Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Gln-Pro-Asp-Ala-Val.

Dimers and Aggregates:
1% as determined by silver-stained SDS-PAGE gel analysis.

Biological Activity:
Murine JE(MCP-1)is fully biologically active when compared to standard. The Biological activity is calculated by its ability to chemoattract Balb/C mouse spleen MNCs at 1.0-20.0ng/ml.

Protein Content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280nm.
2. Analysis by RP-HPLC, using a calibrated solution of Murine JE(MCP-1) as a Reference Standard.

Storage and Stability:
Lyophilized powder may be stored at -20C. Reconstitute to nominal volume by adding sterile dH2O, aliquot and store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
13.8kD
Source: E. coli
Purity: 98% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified. Endotoxin: 0.1ng/ug (IEU/ug).
Concentration: ~0.1mg/ml
Form: Supplied as a lyophilized powder. No additives. Reconstitute in sterile ddH2O 100ug/ml, which can then be further diluted to other aqueous solutions.
