Active Cell Extracts



 

AscentGene Inc. offers nuclear & cytoplasm extracts from a variety of mammalian cells for research applications


  After years of research and development, our team led by Dr. Hui Ge CSO, is proud to offer high quality Active Cell Extracts, isolated from both the cytosol and nucleus. These unique extracts are applicable for a wide variety of functional assays in vitro (see references), such as:  

  1) pre-mRNA splicing assays,
2) polyadenylation assays,
3) transcription assays,
4) translation assays,
5) kinase assays,
6) gel shift assays (protein-DNA/RNA interactions),
7) protein-protein interaction assays, and
8) Western blot assays.






Transcription, capping, and splicing

Translation and post-translational modifications, including glycosylation



  Also, the active nuclear and cytoplasm extracts can be used for native protein isolation and identification, specifically,
as sources of individual cancer biomarkers, tumor suppressors, kinases, cytokines, splicing factors, polyadenylation factors,
transcription factors, ubiquitylation/SUMOylation factors, discovery and characterization of disease-related new proteins,
protein expression profiles, and protein location studies.
