Polyclonal Rabbit Affinity Purified E B IP IH
The 14-3-3 proteins are a highly conserved family of proteins involved in the regulation of cell survival, apoptosis, proliferation and checkpoint control (1-5). Biological regulation by 14-3-3 is mediated through phosphorylation-dependent protein-protein interactions (6). Two different phospho-Ser-containing motifs are found within nearly all known 14-3-3 binding proteins (7). Motif 1 (Arg/Lys and Ser at positions -3 and -2, phospho-Ser at position 0, and Pro at position +2) is found in critical regulatory proteins including Bad, cdc25c, FKHRL1, PKC and c-Raf (5,7). This antibody provides a powerful tool for the discovery and characterization of potential 14-3-3 binding proteins containing this motif and for high throughput drug discovery.
Catalog #0014-33
ApplicationsSuitable for use in, ELISA, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
Recommended DilutionWestern Blot: 1:1000. By 2D gel Western Blot, recognizes a large number of presumptive 14-3-3 binding proteins.
Immunoprecipitation: 1:50
Immunohistochemistry (Paraffin): 1:200
ELISA: 1:1000. Recognizes a wide range of peptides containing the 14-3-3 binding motif
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Clone TypePolyclonal
IsotypeIgG
HostRabbit
Concentration0.35mg/ml
FormSupplied as a liquid in 10mM sodium HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol.
PurityPurified by Protein A and peptide affinity chromatography.
ImmunogenSynthetic phospho- (Ser) 14-3-3-binding-motif peptides.
SpecificityBinds peptides and proteins containing a motif composed of phospho-Ser with proline at the +2 position and arginine or lysine at the -3 position. Antibody binding is phospho-specific and largely independent of other surrounding amino acids. Weakly crossreacts with sequences containing phospho-Thr instead of phospho-Ser in this motif; with sequences containing phospho-Ser surrounded by Phe at the +1 position; with Arg/Lys at the -3 position. No crossreactivity is observed with corresponding non-phosphorylated sequences or with other phospho- Thr/Ser/Tyr -containing motifs.
