Background Information

EIF2A, also named as CDA02, MSTP004 and MSTP089, belongs to the WD repeat EIF2A family. It functions in the early steps of protein synthesis of a small number of specific mRNAs. EIF2A, an alternative initiator tRNA-binding protein, has a key role in the translation of HCV mRNA during HCV infection, in turn promoting eIF2a phosphorylation by activating the eIF2a kinase PKR. This antibody is a rabbit polyclonal antibody raised against residues near the C terminus of human EIF2A, recognizes specifically the 65kd EIF2A protein. EIF2A (Gene ID: 83939) and EIF2S1 (Gene ID: 1965) share the EIF2A symbol/alias in common. EIF2S1 is the alpha subunit of the eIF2 translation initiation complex. Although both of these proteins function in binding initiator tRNA to the 40S ribosomal subunit, the EIF2A protein does so in a codon-dependent manner, whereas eIF2 complex requires GTP.

The provided antibody exceeded all expectations. It worked very well on the first try.Mouse liver was homogenized in Final sample buffer, and then proteins were separated by 10% SDS-PAGE followed by western blot with 11233-1-AP(EIF2A antibody) at a dilution of 1:1000 incubated at 4 degrees Celsius over night in 5% BSA TBST.

• Applications: Western Blot,
