Application Notes

Validated Applications:
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 and the complete data set is available in the UCSC Genome Browser by clicking here.

For optimal results, primary antibody incubations should be performed at 4°C. Individual optimization may be required.

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.

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.

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.

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with KLF5 antibody (pAb).


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
