Multispecies CREB (Total) InstantOne™ ELISA Kit
Representative data for CREB (Total) Multispecies InstantOne™ ELISA. A431 cells were either treated with UCN-01 (1 µg/mL for 60 min) (-) or treated with EGF (2 µg/mL for 10 min) (+). Lysates were prepared as described in the InstantOne User Manual. Cell lysates were analyzed by both immunoblotting (left) and InstantOne™ ELISA (right) for the detection of CREB (Total). The intensity of the band at 37 kDa as detected by immunoblot correlates with InstantOne™ ELISA absorption values.

About This Kit
The InstantOne™ ELISA is specifically engineered for accurate measurement of total human, mouse, and hamster CREB in cell lysates. Detection of rat CREB is also expected. The InstantOne™ ELISA kit allows for fast analysis of samples in approximately one hour. All reagents used in a traditional sandwich ELISA are added in solution to a plate followed by a wash step and detection with the TMB colorimetric substrate.
Target information
CREB (Cyclic AMP response element binding protein) is a 43 kDa basic/leucine zipper transcription factor that binds the cyclic AMP response element (CRE) and activates transcription in response to a variety of extracellular signals including neurotransmitters, hormones, membrane depolarization, and growth and neurotrophic factors. Activation of CREB is dependent upon the phosphorylation of serine 133. Phosphorylation of CREB occurs via p44/42 MAP kinase and p90RSK, and via p38 MAP kinase and MSK1. Although CREB will bind DNA independent of its phosphorylation state, only the phosphorylated form is competent as a transcription factor. CREB binding protein (CBP), a transcriptional coactivator that directly interacts with CREB, binds to CREB in the region of serine 133. CREB is involved in different cellular processes including the synchronization of circadian rhythmicity, differentiation of adipose cells, and learning and memory. In humans, the gene is located on the q arm of chromosome 2. Diseases associated with CREB dysfunction include Alzheimer's Disease, histiocytoma and soft tissue melanoma.
