Typical Testing Data/Standard Curve
Principle of the Assay: CREB ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-CREB antibody and an CREB-HRP conjugate. The assay sample and buffer are incubated together with CREB-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CREB concentration since CREB from samples and CREB-HRP conjugate compete for the anti-CREB antibody binding site. Since the number of sites is limited, as more sites are occupied by CREB from the sample, fewer sites are left to bind CREB-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CREB concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Alternate splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
Uniprot Description
CREB: a transcription factor of the leucine zipper family of DNA binding proteins. Binds as a homodimer to the cAMP-responsive element (CRE). Phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Two splice-variant isoforms have been described.

Product Notes
The Rat CREB1 creb1 (Catalog #AAA7235431) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA7235431 ELISA Kit recognizes Rat CREB1. It is sometimes possible for the material contained within the vial of "cAMP response element-binding protein (CREB), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
