• Catalog Number:

  E011223-1

• Amount:

  50ul

• Form of Antibody:

  Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

• Storage/Stability:

  Store at -20℃/1 year

• class="eg_cn_title"Immunogen:

  The antiserum was produced against synthesized phosphopeptide derived from human 4E-BP1 around the phosphorylation site of threonine 45 (S-T-TP-P-G).

• Purification:

  The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

• Reactivity:

  Human, Mouse, Rat

• SwissProtNo:

  Q13541

• Applications:

  WB: 1:500~1:1000 IHC: 1:50~1:100

• Alter Name:

  4EBP1, EIF4EBP1, Eukaryotic translation initiation factor 4E binding protein 1, Insulin-stimulated EIF-4E binding protein PHAS-I, P/OKCL.6, PHAS-1, PHAS-I

• Specificity Sensitivity:

  4E-BP1 (phospho-Thr45) antibody detects endogenous levels of 4E-BP1 only when phosphorylated at threonine 45. This antibody may cross-react with 4E-BP2 and 4E-BP3 when phosphorylated at equivalent sites.
