Product Specific Information
This antibody recognizes the alpha subunit of eukaryotic translation initiation factor 2 (EIF2-alpha).
Recommended positive controls include:
- Human: Jurkat, CEM, HeLa cells
- Mouse: 3T3L1 cells
- Rat: PC-12 cells
Target Information
EIF2a (Eukaryotic translation initiation factor 2A) is a heterotrimer composed of alpha, beta, and gamma subunits.
This factor facilitates the binding of initiator methionyl-tRNA to the 40S ribosome in an AUG-dependent manner, forming the 43S pre-initiation complex.
Phosphorylation of EIF2A by stress-activated kinases inhibits EIF2B activity, blocking guanine nucleotide exchange and regulating translation initiation under stress conditions.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
