eIF4A1 is a 406aa ATP-dependent RNA helicase belonging to the DEAD box helicase family and eukaryotic initiation factor-4A subfamily with a helicase ATP-binding domain and a helicase C-terminal domain. eIF4F eukaryotic translation initiation complex is formed by the association of eIF4A1 with eIF4E and eIF4E kinase (MNK1), eIF4B, eIF4G, PABPC1. It is closely related to eIF4A2. eIF4A1 is a eukaryotic translation initiation factor involved in protein translation:synthesis where it helps in unwinding the secondary structure of RNA in the 5'-UTR of mRNAs, cap recognition, and is necessary for efficient binding mRNA to the 40S small ribosomal subunit, as well as subsequent scanning for the initiator codon. Ubiquitous expression of the enzyme eIF4A1 is seen in most tissues. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.25-1ug/ml Immunohistochemistry (formalin fixed paraffin embedded): 5ug/ml Optimal dilutions to be determined by the researcher. Positive Control: K562 or RAW cell lysate Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
