Rabbit polyclonal antibody to eIF2a (phospho-Ser49)
Specificity
The antibody detects endogenous level of eIF2a only when phosphorylated at Serine 49.
Applications
WB, IHC, ICC/IF
Dilutions
Western blotting: 1:500~1:1000 Immunohistochemistry: 1:50~1:100 Immunofluorescence: 1:100~1:200
Reactivity
Human, Mouse, Rat
Immunogen
Peptide sequence around phosphorylation site of Serine 49 (L-L-S(p)-E-L) derived from Human eIF2a.
Host
Rabbit
Clonality
Polyclonal
Conjugate
Unconjugated
Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
