| Epithelial Neutrophil-Activating Protein 78 Human Recombinant (CXCL5), ENA 78 Human, 20ug |
Description
Epithelial Neutrophil-Activating Protein 78 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 74 amino acids and having a molecular mass of 8020 Dalton.
The CXCL5 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- Ala -Val-Leu-Arg.
Biological Activity
The biological activity was determined by measuring the dose dependent mobilization of intracellular calcium (calcium flux) with human neutrophils. Significant calcium mobilization is observed with 100ng/mL (corresponding to a Specific Activity of 10,000IU/mg) of recombinant human ENA-78.
The CXCL5 was lyophilized from a concentrated (1mg/ml) solution in water containing no additives.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
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 ENA-78 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 ENA78 although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CXCL5 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.
