Catalog #: CYT-404
Description:
Interleukin-10 Porcine Recombinant produced in E.coli is a single, glycosylated polypeptide chain containing 160 amino acids and having a molecular mass of 18458 Dalton.
The IL-10 is purified by proprietary chromatographic techniques.
Synonyms:
B-TCGF, CSIF, TGIF, IL-10, IL10A, MGC126450, MGC126451, Cytokine synthesis inhibitory factor.
Source:
Escherichia Coli.
Amino Acid Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ser-Ile-Lys-Ser.
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 10 in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The protein was lyophilized with no additives.
Stability:
Lyophilized Interleukin-10 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL10 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 ED50 as determined by the dose-dependant stimulation of MC/9 cell which was found to be < 15ng/ml corresponding to a Specific Activity of 66,667IU/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 0.36 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 IL-10 as a Reference Standard.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
