CYT-387重組大鼠白介素-5(rrIL-5) 2μg/10μg/1mg Prospec

 

 

Background:
 Interleukin-5 (IL5), also known as eosinophil differentiation factor (EDF), is a lineage-specific cytokine for eosinophilpoiesis . It regulates eosinophil growth and activation, and thus plays an important role in diseases associated with increased levels of eosinophils, including asthma. IL5 has a similar overall fold to other cytokines (e.g., IL2, IL4 and GCSF), but while these exist as monomeric structures, IL5 is a homodimer. The fold contains an anti-parallel 4-alpha-helix bundle with a left handed twist, connected by a 2-stranded anti-parallel beta-sheet . The monomers are held together by 2 interchain disulphide bonds.

 
Description :
 Recombinant Rat IL-5 produced in E.Coli is a dimeric, non-glycosylated polypeptide chain containing 113 amino acids and having a molecular mass of 13074 Dalton.
The Recombinant Rat IL-5 is purified by proprietary chromatographic techniques.

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

 
Formulation:
 The protein was lyophilized from a concentrated (1mg/ml) sterile solution with no additives.

 
Solubility:
 It is recommended to reconstitute the lyophilized Rat IL-5 in sterile 18Mω-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

 
Stability:
 
 Lyophilized Rat IL-5 although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution Rat IL-5 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
Met-Glu-Ile-Pro-Met

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

 
Biological Activity:
 ProSpec’s Rat IL-5 is fully biologically active when compared to standard. The ED50 as determined by the dose-dependant stimulation of the proliferation of BCL-1 cells was found to be < 0.15ng/ml.

 
Endotoxin:
 Less than 0.1 ng/µg (IEU/µg) of Recombinant Rat IL-5.

 
Protein content:
 Protein quantitation was carried out by two independent methods:

1. UV spectroscopy at 280 nm using the absorbency value of 0.635 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-5 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.
