Human Rantes (CCL5), (Recombinant)

Recombinant Human Rantes (CCL5) (rHuRantes)

Source: E.Coli

Description: Recombinant Human Rantes produced in E.Coli is a single, non-glycosylated polypeptide chain containing 68 amino acids and having a molecular mass of 7809.2 Dalton. Recombinant Human Rantes 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 CCL5 in sterile 18MO-cm H2O not less than 100 g/ml, which can then be further diluted to other aqueous solutions.

Stability: Lyophilized Rantes although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution CCL5 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 gel.

Amino acid sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Pro-Tyr-Ser-Ser.

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

Biological Activity: rHuRantes is fully biologically active when compared to standard. The activity is determined by the chemoattract of human blood monocytes at a concentration between 1-10ng/ml.

Endotoxin: Less than 0.1 ng/ g (IEU/ g) of recombinant Human Rantes.

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