Catalog #: CHM-340
Description:
Interleukin-8 Porcine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 72 amino acids and having a molecular mass of 8291 Dalton.
The IL-8 is purified by proprietary chromatographic techniques.
Synonyms:
IL-8, CXCL8, Monocyte-derived neutrophil chemotactic factor, MDNCF, T-cell chemotactic factor, Neutrophil-activating protein 1, NAP-1, Protein 3-10C, Granulocyte chemotactic protein 1, GCP-1, Monocyte-derived neutrophil-activating peptide, MONAP, Emoctakin, K60, NAF, LECT, LUCT, 3-10C, LYNAP, SCYB8, TSG-1, AMCF-I, b-ENAP, Alveolar macrophage chemotactic factor I.
Source:
Escherichia Coli.
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 Interleukin 8 in sterile 18MΩ–cm H2O not less than
100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
Lyophilized from a concentrated (1mg/ml) solution in water containing no additives.
Stability:
Lyophilized Interleukin-8 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution CXCL8 should be stored at 4 °C between 2-7 days and for future use below -18 °C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Activity:
The biological activity of IL8 was determined by the dose dependent mobilization of intracellular calcium (calcium flux) with human neutrophils and was found to be >1.0 ng/mL corresponding to a Specific Activity of 1,000,000IU/mg.
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 0.638 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 standard solution of IL-8 as a Reference Standard.
