Expression in Human Cells: StemRD and its partners have developed a highly efficient process to express bioactive recombinant proteins in human cell lines. Since these cells are grown in serum-free, protein-free and chemically-defined media, products made by this process are xeno-free and have human-specific post-transcriptional modifications, such as glycosylation. Using this system, we have been able to produce a number of bioactive proteins that are critical for the growth and differentiation of stem cells.
Protein Purification: We have developed unique and proprietary techniques for the purification of several stem cell factors that are difficult to purify by conventional chromatographic methods. We routinely check the purity and authenticity of our products by HPLC and LC/MS.
Biological Activity: We are experts in stem cell signaling pathways. We measure the biological activities of our products by using pathway-specific bioassays which are more selective and sensitive than other cell-based assays. Our products all have bona-fide bioactivity.
