anti-CREB Antibody

CREB

CREB-1, cAMP-response Element-binding Protein-1, CREB1 , CREB, MGC9284

Transcription factor CREB binds the cAMP response element (CRE) and activates transcription in response to a variety of extracellular signals including neurotransmitters, hormones, membrane depolarization, and growth or neurotrophic factors. Protein kinase A and the calmodulin-dependent protein kinase CaMKII stimulate CREB phosphorylation at Ser133, a key regulatory site controlling transcriptional activity. Phosphorylation at Ser133 is also mediated by p44/42 MAP kinase, p90RSK, p38 MAP kinase and MSK1. CREB appears to play an important role in learning and memory in both flies and mice.

Rabbit

Polyclonal

Rabbit IgG

Human, mouse, rat

Synthetic peptide surrounding amino acid 109 of rat CREB

0.5 mg/ml

Liquid

100 µg (0.5 mg/ml) purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA and 0.01% thimerosal.

Affinity purified

Western blot

Western blotting (0.5-4 µg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes 43 kDa CREB from samples of human, mouse and rat origins.

Shelf time: 12 months in temp.: -20 deg.C

gel pack

The antibody solution should be gently mixed before use.

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
