ChIP Validated ChIP-Seq Validated Western Blot Validated Immunofluorescence Validated Immunocytochemistry Validated

Application Notes

Applications Validated by Active Motif:
ChIP: 5 - 10 µl per ChIP
ChIP-Seq: 5 - 10 µl each
ICC/IF: 1:2,000 dilution
WB*: 1:500 - 1:5,000 dilution

ChIP-Seq validation was performed by Active Motif's Epigenetics Services; the complete data set is available in the UCSC Genome Browser by clicking here.

*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.

This KLF5 antibody was raised against a peptide derived from the N-terminus of mouse KLF5 (Krueppel-like factor 5).


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.


KLF5 antibody (pAb) tested by ChIP-Seq.
ChIP was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 30 ug of chromatin from an adenocarcinoma cell line and 5 µl of antibody. ChIP DNA was sequenced on the Illumina HiSeq and 24 million sequence tags were mapped to identify KLF5 binding sites. The image shows binding across a region of chromosome 2. You can view the complete data set in the UCSC Genome Browser, starting at this specific location, here.

Nuclear extract of K-562 cells (20 µg) probed with the KLF5 antibody (pAb) at a dilution of 1:1,000.


KLF5 (Kruppel-like factor 5, IKLF, Basic transcription element-binding protein 2, BTEB2) is a zinc-finger transcription factor that plays a role in cell proliferation, differentiation, cell cycle regulation, angiogenesis, and carcinogenesis and is especially important in epithelial cells. KLF5 (along with KLF2 and KLF4) are highly expressed in undifferentiated mouse embryonic stem cells and downregulated during early stages of differentiation. KLF5 and KLF2 can substitute for KLF4 in the reprogramming of differentiated cells into stem cells. KLF5 has a pro-proliferative role in cells and loss of both alleles of KLF5 is embryonic lethal.

Positive Control

Active Motif's K-562 nuclear extract (Catalog No. 36015) can be used as a positive control for KLF5 antibody.
