Human Epithelial Neutrophil-Activating Protein 78 (CXCL5), (Recombinant)

Recombinant Human Epithelial neutrophil-activating protein 78 (CXCL5)

Source: E.Coli

Description: Recombinant Human ENA-78 produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 74 amino acids and having a molecular mass of 8020 Dalton. Recombinant Human ENA-78 is purified by proprietary chromatographic techniques.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation: Lyophilized from a concentrated (1mg/ml) solution in water containing no additives.

Solubility: It is recommended to reconstitute the lyophilized ENA-78 in sterile 18MO-cm H2O not less than 100 g/ml, which can then be further diluted to other aqueous solutions.

Stability: Lyophilized ENA-78 although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution ENA-78 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.

Purity: Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. (c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained.

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. .

Dimers and aggregates: Less than 1% as determined by silver-stained SDS-PAGE gel analysis.

Biological Activity: Recombinant Human ENA-78 is fully biologically active when compared to standard. The Activity is calculated by the ability to chemoattract Human peripheral blood neutrophils using a concentration of 5-10 ng/ml.

Endotoxin: Less than 0.1 ng/ g (IEU/ g) of Recombinant Human Epithelial neutrophil-activating protein 78

Protein content: Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm . 2. Analysis by RP-HPLC, using a calibrated solution of ENA-78 as a Reference Standard.
