Name: Active Recombinant Human GM-CSF/IL-3 (PIXY321) Fusion Protein
SKU: CSF3&IL3-5H

Species :	Human
Source :	E.coli
Tag :	Non
Description :	Synergism of IL3 together with GMCSF causes a rapid rise in neutrophils due to GMCSF and a slower rise in platelets due to IL3 which has strong stimulated effect on hematopoietic cells.The analog of GMCSF/IL3 is PIXY321. Results indicate that PIXY321 can stimulate multilineage hematopoiesis in vivo and enhance neutrophil and platelet recovery following chemotherapy and bone marrow transplantation (BMT). These results suggest that PIXY321 elicits the biological effects of both its component cytokines and represents a novel means of delivering two independent but interactive cytokines in combination.
Form :	The protein was lyophilized after extensive dialysis against 10mM PBS, pH= 7.4±0.1 and 0.1% BSA.
Bio-activity :	The ED50 as determined by the dose-dependant stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line) is< 0.2="" ng/ml,="" corresponding="" to="" a="" specific="" activity="" of="" 5="" x106="">
Molecular Mass :	GMCSF/IL3 fusion protein Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain having a Mw of 30kDa. PIXY321 is purified by proprietary chromatographic techniques.
Purity :	Greater than 96.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis bySDS-PAGE.
Usage :	FOR RESEARCH USE ONLY
Quality Control Test :	Lyophilized PIXY321 although stable at room temperature for 3 weeks, should be stored desiccated below -18 centigrade. Upon reconstitution PIXY321should be stored at 4 centigrade between 2-7 days and for future use below -18 centigrade.
Reconstitution :	It is recommended to reconstitute the lyophilized PIXY321 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solution.
Warning :	Avoid repeated freeze-thaw cycles.
