The antibody is prepared from pooled rabbit serum by affinity purification using a column to which the peptide immunogen was coupled.


Biological Significance: ExpandCollapse

The eIF4A, eukaryotic initiation factor 4A, are a set of proteins, eIF4A1, eIF4A2, and eIF4A3, that belong to the extensive DEAD-box RNA helicase family (Weinstein et al., 1997). They are involved in many aspects of RNA metabolism by virtue of their RNA-binding capacity and ATPase activity (Lu et al., 2014).  eIF4A2 is a highly conserved gene for one of the protein-synthesis initiation factors involved in the binding of mRNA to the ribosome (Gingras et al., 1999). In humans eIF4A2 is expressed in all normal tissues, though highly expressed in skeletal muscle (Sudo et al., 1995).  Studies suggest eIF4A2 may play a role in some cancers, specifically breast and lung cancer, along with melanoma (Shaoyan et al., 2013).

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
