The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/2000. Detects a band of approximately 74 - 81 kDa (predicted molecular weight: 74 - 81 kDa).
1/5000 - 1/20000.
Use at an assay dependent dilution.
FunctionRegulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFB), which is proposed to facilitate the transition from abortive to production elongation by phosphorylating the CTD (carboxy-terminal domain) of the large subunit of RNA polymerase II (RNAP II).
Tissue specificityUbiquitously expressed.
Sequence similaritiesBelongs to the cyclin family. Cyclin C subfamily.
