CAT No.BT-CHM-341

Macrophage Inflammatory Protein-3 Beta Mouse Recombinant (CCL19), MIP 3b Mouse, 20ug

---

Description
Macrophage Inflammatory Protein-3 beta Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 83 amino acids and having a molecular mass of 9216 Dalton.
The MIP-3b 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, Gly-Ala-Asn-Asp-Ala.

Biological Activity
The Activity of CCL19 is calculated by the ability to chemoattract Human mature dendritic cells using a concentration of 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.

The CCL19 was lyophilized from a concentrated (1mg/ml) solution in water 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 0.91 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-3b as a Reference Standard.

Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Macrophage Inflammatory Protein-3b 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-3b although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CCL19 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.
