Product background
StemBeads® VEGF is a patented growth factor supplement that is designed to culture cells with Vascular Endothelial Growth Factor more efficiently, with greater control and fewer medium changes. StemBeads® VEGF are microparticles composed of an FDA approved, biodegradable polymer that is loaded with recombinant human VEGF (Qk048).
Under the microscope, StemBeads® will appear as small dark spheres, and with time, will break down while releasing the encapsulated protein at a controlled rate. Controlled delivery and stable levels of growth factors improve cell cultures while saving researchers valuable time and resources.
Please note: this product is in beta testing and is only made to order at this time (expected 6 week lead time). Data for this product is limited. Instructions for use are available upon request.

FAQ
Will StemBeads® DISC™ Devices interfere with my downstream application of the cells?
Cells cultured with DISC™ have been used in a variety of downstream applications, including FACS, RNA/DNA extraction, nucleofection, differentiation, organoid generation, and others with no negative effects. If necessary for differentiation protocols, DISCs™ can be cleanly removed using a low powered vacuum tip.
What if I want to use a different concentration, can the protein release be adjusted?
The protein concentration can be adjusted based on the number of StemBeads® that you use. The release rate has a linear correlation with the amount of StemBeads® used. For example, 8 µl of StemBeads® per ml of media releases at a concentration of 10 ng/ml. However, if you desire half of that concentration, such as 5 ng/ml, then adjust the concentration to 4 µl of StemBeads® per ml media to achieve the concentration of 5 ng/ml.
The pH indicator in my growth medium appears very yellow when not changing media daily. Is this a problem?
No, this is not a problem or indication of cell quality. Extensive testing has been performed to access the cell quality when using StemBeads®. All phenotypic and functional assays have shown cell quality as good or better than current feeding regimens. For best assessment of cells, wash cells once prior to observation.
