Cet anticorps anti-EIF2A Polyclonal Lapin (ABIN5689682) détecte spécifiquement EIF2A dans WB, IHC et IF.
L’anticorps est réactif avec des échantillons de Humain, Souris et Rat.
This antibody detects endogenous level of eIF2α, only when phosphorylated at serine 51.
Purification
Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Immunogène
eIF2a (Phospho-Ser51) antibody was raised against a peptide sequence around phosphorylation site of serine 51 (E-L-S (p) -R-R) derived from Human eIF2α,.
Functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B.
