CYT-401重組豬粒-巨噬細胞集落刺激因子(rpGM-CSF) 2μg/10μg/1mg Prospec

 

 

Background:
 The overall structure of GM-CSF is highly compact and globular with a predominantly hydrophobic core, is characterised by a 4-alpha-helix bundle. The helices are arranged in a left-handed anti-parallel fashion, with two overhand connections. Within the connections is a two-stranded anti-parallel beta-sheet. The tertiary structure has a topology similar to that of (pig) growth factor and interferon-beta. Most of the proposed critical regions for receptor binding are located on a continuous surface at one end of the molecule that includes the C terminus .

Granulocyte Macrophage Colony Stimulating Factor is produced in response to a number of inflammatory mediators by mesenchymal cells present in the hemopoietic environment and at peripheral sites of inflammation. Granulocyte Macrophage-CSF is able to stimulate the production of neutrophilic granulocytes, macrophages, and mixed granulocyte-macrophage colonies from bone marrow cells and can stimulate the formation of eosinophil colonies from fetal liver progenitor cells. GM-CSF can also stimulate some functional activities in mature granulocytes and macrophages. GM-CSF receptors shows significant homologies with other receptors for hematopoietic growth factors , including IL2-beta, IL-3 , IL-6 , IL-7 , EPO and the Prolactin receptors

 
Description :
 Recombinant Porcine GM-CSF produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 127 amino acids and having a molecular mass of 14381 Dalton.
Porcine GM-CSF is purified by proprietary chromatographic techniques.

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

 
Formulation:
 The protein was lyophilized with no additives.

 
Solubility:
 It is recommended to reconstitute the lyophilized Porcine GM-CSF in sterile 20mM AcOH (acetic Acid) not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

 
Stability:
 
 Lyophilized Porcine GM-CSF although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution GM-CSF 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 95.0% 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-Thr-Arg-Pro.

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

 
Biological Activity:
 ProSpec’s Porcine GM-CSF is fully biologically active when compared to standard. The ED50 as determined by the dose-dependant stimulation of the proliferation TF-1 cell line is < 20 ng/ml.

 
Endotoxin:
 Less than 0.1 ng/µg (IEU/µg) of GM-CSF .

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

1. UV spectroscopy at 280 nm using the absorbency value of 0.977 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 calibrated solution of Recombinant Porcine GM-CSF 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.
