Cdk9 [p Thr29] Antibody - BSA Free

Western Blot: Cdk9 [p Thr29] Antibody [NBP1-77756] - Shows detection of phosphorylated CDK9. 100 ng of purified P-TEFb, which contains CDK9 and its regulatory cyclin T1 subunit, was incubated with ATP in the presence or absence of Brd4, a protein known to induce CDK9 phosphorylation at T29. The primary antibody was used at a 1:1000 dilution.

Cdk9 [p Thr29] Antibody - BSA Free Summary

• Description: This product was affinity purified from monospecific antiserum by immunoaffinity chromatography using phospho-peptide coupled to agarose beads followed by solid phase adsorption against nonphospho-peptide
  
  Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.
• Immunogen: This affinity purified Cdk9 [p Thr29] Antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to residues surrounding T29 in the human Cdk9 protein. (Uniprot: P50750)
• Modification: p Thr29
• Specificity: This antibody is specific for human CDK9 protein phosphorylated at T29. A BLAST analysis was used to suggest cross-reactivity with CDK9 from human, mouse and rat based on 100% homology with the immunizing sequence. Cross-reactivity with CDK9 from other sources has not been determined.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: CDK9
• Purity: Immunogen affinity purified

Applications/Dilutions

• Dilutions:
  • ELISA 1:5000-1:24000
  • Immunoprecipitation 1:100
  • Western Blot 1:200-1:2000
• Application Notes: This affinity purified antibody has been tested for use in ELISA and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 42 kDa in size corresponding to phosphorylated CDK9 protein by western blotting in the appropriate cell lysate or extract. This phospho-specific polyclonal antibody reacts with human CDK9 pT29 and shows minimal reactivity by ELISA against the non-phosphorylated form of the immunizing peptide.

Reactivity Notes

Background

CDK9 (PITALRE) (also known as cyclin-dependent kinase 9, Serine/threonine-protein kinase PITALRE, C-2K and Cell division cycle 2-like protein kinase 4) is a member of the cyclin-dependent protein kinase (CDK) family.? CDK family members are highly similar to the gene products of S. cerevisiae cdc28 and S. pombe cdc2 and are known as important cell cycle regulators.? CDK9 (PITALRE) interacts with a conserved domain in the TRAF-C region of the tumor necrosis factor signal transducer TRAF2. ?This kinase was also found to be a component of the multiprotein complex TAK/P-TEFb, which is an elongation factor for RNA polymerase II-directed transcription and functions by phosphorylating the C-terminal domain of the largest subunit of RNA polymerase II. This protein forms a complex with, and is regulated by, its regulatory subunit, cyclin T or cyclin K. HIV-1 Tat protein.
