Cet anticorps anti-EIF2A Polyclonal Lapin (ABIN362446) détecte spécifiquement EIF2A dans IHC et IF.
L’anticorps est réactif avec des échantillons de Humain, Souris et Rat.
The antibody detects endogenous level of eIF2a only when phosphorylated at Serine 49.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific phosphopeptide. The antibody against non-phosphopeptide was removedby chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogène
Peptide sequence around phosphorylation site of pSer49 (L-L-S (p) -E-L) derived from Human eIF2a. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.
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.
