The eIF2alpha Antibody (CAB0764) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, produced in rabbits, has high reactivity with human samples and has been validated for use in Western blot applications. It specifically binds to the EIF2S1 protein, allowing for accurate detection and analysis in a variety of cell types.EIF2S1, also known as eukaryotic translation initiation factor 2 subunit 1, plays a crucial role in the initiation of protein synthesis and is essential for cellular functions. Dysregulation of EIF2S1 has been implicated in various diseases, including cancer and neurodegenerative disorders.
This antibody is validated for use in WB, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

The translation initiation factor EIF2 catalyzes the first regulated step of protein synthesis initiation, promoting the binding of the initiator tRNA to 40S ribosomal subunits. Binding occurs as a ternary complex of methionyl-tRNA, EIF2, and GTP. EIF2 is composed of 3 nonidentical subunits, the 36-kD EIF2-alpha subunit (EIF2S1), the 38-kD EIF2-beta subunit (EIF2S2; MIM 603908), and the 52-kD EIF2-gamma subunit (EIF2S3; MIM 300161). The rate of formation of the ternary complex is modulated by the phosphorylation state of EIF2-alpha (Ernst et al., 1987 [PubMed 2948954]).
