Recombinant Rat MIP-1a produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 69 amino acids and having a molecular mass of 7853 Dalton. Recombinant Rat MIP-1a is purified by proprietary chromatographic techniques.

Amino Acid Sequence:
The sequence of the first five N-terminal amino acids: Ala-Pro-Tyr-Gly-Ala.

Biological Activity:
Recombinant Rat MIP-1a is fully biologically active when compared to standard. The Activity is calculated by the ability to chemoattract of rat peritoneal macrophages using a conc. of 60 ng/ml.

Protein Content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 1.38 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of MIP-1 alpha as a Reference Standard.

Reconsitution:
Reconstitute in ddH2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability:
Lyophilized MIP-1alpha although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution MIP-1 alpha should be stored at 40C between 2-7 days and for future use below -180C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.

Molecular Weight:
7.85kD
 Source: E. coli
Purity: 95% as determined by RP-HPLC, or SDS-PAGE.
Concentration: 1mg/ml
Form: Supplied as a lyophilized powder without additives.
