產品介紹
CYT-210 | 重組人白介素-3(rHuIL-3) | 2μg/10μg/1mg | Prospec |
Background : | |
Interleukin-3 (IL-3) is a cytokine produced by activated T-cells and mast cells that is active on a broad range of hematopoietic cells and in the nervous system and appears to be important in several chronic inflammatory diseases | |
Description : | |
Recombinant Human IL-3 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 133 amino acids and having a molecular mass of 15000 Dalton. The rHuIL-3 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 5mg HSA and 4.3mg Sodium Chloride. | |
Solubility: | |
It is recommended to reconstitute the lyophilized rHuIL-3 in sterile 18Mω-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | |
Stability: | |
Lyophilized rHuIL-3 although stable at room temperature for 3 weeks, should be stored desiccated below -18 C. Upon reconstitution rHuIL-3 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 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 Ala-Pro-Met-Thr-Gln. | |
Dimers and aggregates: | |
Less than 1% as determined by silver-stained SDS-PAGE gel analysis. | |
Biological Activity: | |
ProSpec's rHuIL-3 is fully biologically active when compared to standard. The ED50 as determined by the dose-dependant stimulation of TF-1 cells is less then 0.1 ng/ml, corresponding to a Specific Activity of 1 x 107 IU/mg. | |
Endotoxin: | |
Less than 0.1 ng/µg (IEU/µg) of rHuIL-3. | |
Protein content: | |
Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.84 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 (InliGenetics). 2. Analysis by RP-HPLC, using a standard solution of IL-3 as a Reference Standard. | |
Usage: | |
Prospec'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. |
