Introduction
EIF5A is the only known protein containing the unusual amino acid hypusine, formed by the sequential action of deoxyhypusine synthase and deoxyhypusine hydroxylase using spermidine as a substrate. This protein is involved in the first step of peptide bond formation in translation; however, further evidence suggests that it acts as a universally conserved translation elongation factor. EIF5A modulation is linked to cell proliferation and cancer development. Increased EIF5A expression is observed in the peripheral blood mononuclear cells (PBMCs) of HIV-1 infected individuals. EIF5A regulates crucial cellular processes, including cell survival and senescence, by influencing the stability of specific mRNAs. Heat stress can lead to a decrease in EIF5A levels in human pancreatic cancer cells, suggesting that EIF5A stability plays a role in determining cell fate following severe heat stress.
Formulation
The antibody is supplied as a 1 mg/ml solution in phosphate-buffered saline (PBS) at pH 7.4, containing 0.1% sodium azide as a preservative.
Storage Procedures
For short-term storage (up to 1 month), the antibody can be stored at 4°C. For long-term storage, it is recommended to store the antibody at -20°C. Avoid repeated freeze-thaw cycles to maintain antibody stability.
Stability / Shelf Life
The antibody has a shelf life of 12 months when stored at -20°C and a shelf life of 1 month when stored at 4°C.
Applications
The EIF5A antibody has been validated for use in ELISA, Western blot, and Immunofluorescence assays to ensure its specificity and reactivity. However, it is essential to optimize the antibody concentration for each specific application to achieve optimal results. The recommended dilution range for Western blot and Immunofluorescence is 1:250 to 1:500. A starting dilution of 1:250 is recommended for initial experiments.
