Micro-encapsulated high purity protein
StemBeads® technology for controlled-release
Lot-to-lot consistency in bioactivity

We are a company founded and run by scientists to provide a service and support innovation in stem cell biology and regenerative medicine. All our products are exceptionally high purity, with complete characterisation and bioactivity analysis on every lot.
StemBeads® Qkine NT-3 is a patented growth factor supplement designed to culture cells with neurotrophin-3 more efficiently, with greater control and fewer medium changes. StemBeads® Qkine NT-3 are microparticles composed of an FDA approved, biodegradable polymer that is loaded with Qkine recombinant human NT-3 (Qk058, Qkine NT-3 protein is a non-covalently linked homodimer with a molecular weight of 27.3 kDa, animal origin-free (AOF), carrier-free, tag-free, and non-glycosylated to ensure its purity with exceptional lot-to-lot consistency. It is suitable for the culture of reproducible and high-quality cortical neurons and oligodendrocytes.). 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.
Please note: this product is in development and beta testing. The product 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.
StemBeads® can be easily removed prior to analysis by washing 1-2 times with PBS, DMEM, F12 or any other basal medium preferred. For suspension cultures, there are a variety of strainer pore sizes to allow for separation. Cells cultured with StemBeads® have been used in a variety of downstream applications, including but not limited to: immunofluorescence, FACS, RNA/DNA extraction, nucleofection, differentiation etc.
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.
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.
