Application Notes

Validated Applications:
WB: 1 - 2 µg/ml dilution

For optimal results, primary antibody incubations should be performed at room temperature. The addition of 0.1% Tween 20 to all Blotto solutions may also reduce background. Individual optimization may be required.


This CREB antibody was raised against a synthetic peptide corresponding to human CREB.


PBS containing 0.02% sodium azide. Sodium azide is highly toxic.


CREB antibody (mAb) tested by Western blot.

CREB mAb tested by Western blot.
Detection of CREB by Western blot analysis. A protein band of approximate molecular weight of 43 kDa was detected using HeLa whole-cell extract and CREB mAb at a dilution of 2 µg/ml.


CREB (cAMP response element binding) transcription factor binds as a homodimer to specific DNA sequences called cAMP response elements (CRE) and regulates transcription. CREB belongs to the leucine zipper family of DNA binding proteins. CREB induces transcription in response to hormonal stimulation.

Positive Control

Active Motif's HeLa whole-cell extract (Catalog No. 40050) can be used as a positive control for CREB antibody.


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.
