The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser383 of human Elk-1.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.

Biological Significance: ExpandCollapse

Elk-1 is a transcription factor involved in mediating gene transcription in response to growth factors (Hill and Treisman, 1995). Elk-1 is thought to be phosphorylated by MAP kinase at Ser383 and phosphorylation at this site is essential for the transcriptional activity of Elk-1 (Li et al., 2003). Phosphorylation of Elk-1 has also been implicated in synaptic plasticity in the adult hippocampus (Thiels et al., 2002).

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg BSA per ml and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Elk-1 ser383 Antibody
Western blot of recombinant Elk-1 showing specific immunolabeling of the ~46 kDa Elk-1 phosphorylated at Ser383 in the right lane (-). Phosphospecificity is shown in the left lane (+) where immunolabeling is blocked by preadsorption of the phosphopeptide used as the antigen, but not by the corresponding non-phosphopeptide (not shown).
