| Specificity / Sensitivity | eIF2B-epsilon Antibody detects endogenous levels of total eIF2B-epsilon protein. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids near the middle of human eIF2B-epsilon. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting

| Background | Phosphorylation of the eukaryotic initiation factor 2 (eIF2) α subunit is a well-documented mechanism to downregulate protein synthesis under a variety of stress conditions. eIF2 binds GTP and Met-tRNAi and transfers Met-tRNA to the 40S subunit to form the 43S preinitiation complex (1,2). eIF2 promotes a new round of translation initiation by exchanging GDP for GTP, a reaction catalyzed by eIF2B (1,2). Kinases that are activated by viral infection (PKR), endoplasmic reticulum stress (PERK/PEK), amino acid deprivation (GCN2), or heme deficiency (HRI) can phosphorylate the α subunit of eIF2 (3,4). This phosphorylation stabilizes the eIF2-GDP-eIF2B complex and inhibits the turnover of eIF2B. Induction of PKR by IFN-γ and TNF-α induces potent phosphorylation of eIF2α at Ser51 (5,6). eIF2B, a guanine nucleotide exchange factor, is composed of 5 subunits, the largest of which is eIF2B-epsilon (7). Multiple in vivo phosphorylation sites have been identified on eIF2B-epsilon (8). Casein Kinase II can phosphorylate eIF2B-epsilon at Ser717/718 to allow for association with its substrate eIF2. Phosphorylation at Ser544 allows GSK-3 to phosphorylate the key regulatory site Ser540. A fifth eIF2B-epsilon phosphorylation site, Ser466, can be phosphorylated by casein kinase I.

The importance of antibody molecules was first recognized in the 1890s, when it was shown that immunity to tetanus and diphtheria was caused by antibodies against the bacterial exotoxins (1 ). Around the same time, it was shown that antisera
General comments: Antibodies, like most proteins, do not like to be freeze-thawed. Avoid repetitive freezing of your solution. The best way to store your antibody is to keep a high protein concentration (>1 mg/ml), add some protease
