Applications

Western Blot Validated

Application Notes

Applications Validated by Active Motif:
WB*: 1:500 - 1:2,000 dilution

*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.

Immunogen

This CTBP antibody was raised against a peptide within the C-terminal region of human CTBP.

Buffer

Rabbit serum containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

 

CTBP antibody (pAb) tested by Western blot.
Nuclear extract of Jurkat cells (30 µg per lane) probed with CTBP antibody (pAb) at a dilution of 1:2,000.

Background

CTBP (C-terminal Binding Protein, CTBP1) is a transcriptional repressor that was originally identified by virtue of its ability to bind the C-terminus of E1A proteins. CTBP serves as a co-repressor for a number of DNA binding transcription factors. CTBP is part of a variety of co-repressor complexes, many of which include HDAC proteins. CTBP also interacts with vertebrate Polycomb proteins including Pc2, suggesting that repression of many CTBP-regulated genes also involves recruitment of the Polycomb complex.

Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Avoid repeated freeze/thaw cycles by aliquoting items into single-use fractions for storage at -20°C for up to 2 years. Keep all reagents on ice when not in storage.
