Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, ChIP=Chromatin IP,


Species predicted to react based on 100% sequence homology: Hamster, Bovine, Dog, Pig,

Specificity / Sensitivity

INTS9 Antibody recognizes endogenous levels of total INTS9 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding His601 of human INTS9 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using INTS9 Antibody.



Immunoprecipitation of INTS9 from HCT 116 cell extracts using Normal Rabbit IgG #2729 (lane 2) or INTS9 Antibody (lane 3). Lane 1 is 10% input. Western blot analysis was performed using INTS9 Antibody.

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 10 µl of INTS9 Antibody or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human RNU2-1 Promoter Primers #14084 and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.


The integrator complex is an evolutionarily conserved complex that is composed of at least 12 subunits in humans. It is thought to be a multifunctional complex with roles in orchestrating snRNA 3' end processing with transcription termination, DNA double-stranded break repair, hematopoietic development, and cell cycle progression (1-6). The integrator subunits (INTS) 9 and 11 are thought to be the catalytic subunits of the complex and are essential for the function of the complex (6,7). Research studies indicate that the integrator complex is recruited to snRNA genes through its interaction with the carboxy-terminal domain (CTD) of Rpb1, the largest subunit of RNA polymerase II (8). Phosphorylation of the Rpb1 CTD heptapeptide repeat residues Ser2 and Ser7 is required for efficient binding of integrator subunit proteins (9).
