| Macrophage Inflammatory Protein-1 Alpha Human Recombinant (CCL3), MIP 1a Human, 20ug |
Description
Macrophage Inflammatory Protein-1 alpha Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7820 Dalton.
The MIP-1a is purified by proprietary chromatographic techniques.
Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be, Ala-Ser-Leu-Ala-Ala.
Biological Activity
The Activity is calculated by the ability of chemo-attraction of Human monocytes using 1-10ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
The protein was lyophilized from 0.55 mg/ml solution containing no additives.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein content
Protein quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm using the absorbency value of 0.9 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-1a as a Reference Standard.
Purity
Greater than 98.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility
It is recommended to reconstitute the lyophilized Macrophage Inflammatory Protein-1a in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Source
Escherichia Coli.
Stability
Lyophilized MIP-1a although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CCL3 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
