Cat-Nr.	300-090H-L
Size	6 mg
Price	130 €
Source	Cattle
Formulation	lyophilized (freeze-dried)
Purification	Crude extract
Biological Activity	Optimum concentration for human umbilical vein endothelial cells (HUVEC) range from 50-200 µg/ml, optimal concentration with heparin (30 µg/ml) is about 12 µg/ml.
Species Reactivity	human cells, mouse cells, rat cells, cattle cells, pig cells
Buffer	water
Reconstitution	Reconstitute the contents of the vial in 2 ml of prewarmed (37°C) sterile PBS or water. Gently rotate the vial until the contents are dissolved. This stock solution may be further diluted in sterile tissue culture media to obtain the desired working concentrations. It is recommended that medium containing diluted product is aseptically filtered prior to use.
Stability and Storage	Also stable at 4°C for several weeks it is recommended to store the product below 0°C. After reconstitution the product should be stored in aliquots at -20°C to -70°C.
Application Remarks	Can be used for lymphatic endothelial cell cultivation.
Synonyms	Endothelial cell growth factor (ECGF); Endothelial cell growth supplement (ECGS)
Description	Endothelial cell growth factor (ECGF) is an extract of bovine brain containing growth promoting factors for vascular endothelial cells of mammalian origin. Endothelial cell growth factor is prepared using a modification of the method of Maciag, et al. (1979) lyophilized from a sterile solution containing NaCl and streptomycin sulfate. ECGFpro2 is supplemented with recombinant human VEGF-C (corresponding to 50 ng/ml) a concentration sufficient for the cultivation of lymphatic endothelial cells. Lymphatic endothelial cells from human skin can be established as primary cultures by traditional methods. The serial propagation of these cells has proved to be difficult. The long-term propagation of these cells in vitro can be achieved with an extract prepared from bovine brain. The introduction of a fibronectin or collagen matrix to the cell culture system allows cultivating endothelial cells at clonal densities. With ECGF, the FCS requirement can be reduced. Heparin potentiates the mitogenic activity of crude preparations of ECGF. ECGF has also been reported to eliminate the need for feeder cells in the clonal growth of hybridomas and other cell types.
