EIF5A, a conserved eukaryotic protein with a unique hypusine modification, plays a critical role in protein synthesis by promoting peptide release and alleviating ribosomal stagnation. This hypusination, catalyzed by DHPS and DOHH, is essential for EIF5A's activity and impacts various cellular processes like autophagy, cell aging, and energy metabolism. EIF5A's involvement in diseases such as cancer and its strict regulation by hypusination underscore its significance in cell biology. In essence, EIF5A's specialized function and modification make it a key player in cellular activities and disease pathways.

IHC image of CSB-RA932542A0HU diluted at 1:100 and staining in paraffin-embedded human colon cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
Immunofluorescence staining of Hela Cells with CSB-RA932542A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeated by 0.2% TritonX-100, and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Rabbit IgG (H+L).
Overlay histogram showing Jurkat cells stained with CSB-RA932542A0HU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then incubated in 10% normal goat serum to block non-specific protein-protein interactions followedby the antibody (1µg/1*106 cells) for 1 h at 4℃.The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 30min at 4℃. Control antibody (green line) was Rabbit IgG (1µg/1*106 cells) used under the same conditions. Acquisition of >10,000 events was performed.
