Flow cytometric analysis of SK-N-MC cells using CREB (48H2) Rabbit mAb (PE Conjugate) (green) compared to Rabbit (DA1E) mAb IgG XP® Isotype Control (PE Conjugate) #5742 (red).
|REACTIVITY||H M R Mk Dm|
This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometry analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated CREB (48H2) Rabbit mAb #9197.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibodies. Protect from light. Do not freeze.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to fixation.

CREB (48H2) Rabbit mAb (PE Conjugate) recognizes endogenous levels of total CREB-1 protein. The antibody does not cross-react with other ATF/CREB family members.Species Reactivity:
Human, Mouse, Rat, Monkey, D. melanogaster
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human CREB-1 protein.
CREB is a bZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth, and neuronal differentiation in certain neuronal populations (1-3). Additionally, CREB signaling is involved in learning and memory in several organisms (4-6). CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways including Erk, Ca2+, and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV, and MAPKAPK-2 (7-9).
