CREB [p Ser271] Antibody

Immunocytochemistry/Immunofluorescence: CREB [p Ser271] Antibody [NBP3-23250] - Immunocytochemical labeling of phosphorylated CREB in control and calyculin A-treated A431 cells. The cells were fixed in paraformaldehyde and permeabilized using NP-40 before labeling with rabbit polyclonal CREB (Ser-271). The antibody was detected using goat anti-rabbit DyLight(R) 594.

Western Blot: CREB [p Ser271] Antibody [NBP3-23250] - Western blot analysis of human A431 cells treated with calyculin A (100 nM) for 30 min. (lanes 1, 3, & 5) then blots were treated with lambda phosphatase (lanes 2, 4, & 6). The blots were probed with anti-CREB (N-terminal region) (lanes 1 & 2), anti-CREB (Ser-133) (lanes 3 & 4), and anti-CREB (Ser-271) (lanes 5 & 6).

CREB [p Ser271] Antibody Summary

• Description: Stable for at least 1 year at -20°C.
• Immunogen: Phospho-CREB (Ser-271) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding Ser-271 in human CREB. This sequence is well conserved in rat, mouse, chicken, and zebrafish CREB. The site has some homology to the conserved site in ATF1 (Ser-198) and CREM (Ser-287). [UniProt# P16220]
• Modification: p Ser271
• Specificity: The antibody detects a 43 kDa protein corresponding to the molecular mass of CREB on SDS-PAGE immunoblots of human A431, Jurkat, and rat PC12 cells treated with Calyculin A, but is not observed after lambda phosphatase treatment.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: CREB1
• Purity: Antigen Affinity-purified

Applications/Dilutions

Background

CREB (cAMP responsive element binding protein 1) stimulates transcription. CREB is involved in learning and memory. This protein is known to have interactions with HIST1H3B, HIST1h3A, HIST1H3C, HIST1H3D and HIST1H3E. CREB has been studied in relation to several diseases and disorders including Rubinstein-Taybi syndrome, Alzheimer's disease, leukemia and brain disease.

FAQs for CREB Antibody (NBP3-23250). (Showing 1 - 1 of 1 FAQ).

1. May I know which creb1 antibody is good for ChIP? I found a paper using your rabbit polyclonal creb1 antibody for ChIP but they didn't indicate the catalog number.
   • We are not aware of any of our Creb1 antibodies being used in ChIP at this time. If you can provide us with the PMID of the paper you are referring to I can contact the author. Otherwise, you can use our Innovators Reward Program to try an antibody in a novel species and application.
