Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.Hexim 1 is a transcriptional regulator which functions as a general RNA polymerase II transcription inhibitor. Hexim 1 works in cooperation with 7SK snRNA to sequester P-TEFb in a large inactive 7SK snRNP complex, preventing RNA polymerase II phosphorylation and subsequent transcriptional elongation. View All» Specificity: This antibody recognizes Hexim1 at the N-terminus. View All» Molecular Weight: ~53 kDa View All» Epitope: N-terminus View All» Immunogen: KLH-conjugated linear peptide corresponding to human Hexim 1 at and around the N-terminus. View All» Background Information: Hexim1 is a transcriptional regulator which functions as a general RNA polymerase II transcription inhibitor. Hexim1 works in cooperation with 7SK snRNA to sequester P-TEFb in a large inactive 7SK snRNP complex, preventing RNA polymerase II phosphorylation and subsequent transcriptional elongation. The 7SK snRNP complex is composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), Hexim1, Hexim2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs. Hexim1 also interacts with the N-CoR complex through NCOR1, ESR1, NR3C1, and may interact with NF-kappa-B through REL A. Hexim1 is located in the nucleus where it can bind with alpha-importin, and can also be found in the cytoplasm. Hexim1 is up-regulated by HMBA (hexamethylene bisacetamide) at the protein level and down-regulated by estrogen. View All» Species Reactivity:

View All» Application Notes: Immunoprecipitation from RIP lysate:Representative lot data.RIP lysate from HeLa cells (~2 X 10E7 cell equivalents per IP) was subjected to immunoprecipitation using either 5 µg of a normal rabbit IgG or 5 µg of Anti-Hexim 1 antibody. Ten percent of the precipitated proteins (lane 3: rabbit IgG, lane 2: Hexim 1) and HeLa lysate (lane 1) were resolved by electrophoresis, transferred to PVDF and probed with anti-Hexim antibody (1:1000). Proteins were visualized using One-Step™ IP-Western kit (GenScript Cat. # L00231) Arrow indicates Hexim 1 (~53 kDa) (Please see figures).Western Blot Analysis: Representative lot data.HeLa cell lysate was resolved by electrophoresis, transferred to PVDF membranes and probed with Anti-Hexim 1 (1:10,000 dilution). Proteins were visualized using a Donkey anti-Rabbit conjugated to HRP using a chemiluminescence detection system. Arrow indicates Hexim 1 (~53 kDa) (Please see figures).Western Blot (SNAP ID®) Analysis: Representative lot data.HeLa cell lysate was resolved by electrophoresis, transferred to PVDF membranes and probed with Anti-Hexim 1 (1:250 dilution). Proteins were visualized using a Donkey anti-Rabbit conjugated to HRP using a chemiluminescence detection system. Arrow indicates Hexim 1 (~53 kDa) (Please see figures).
