Application Details

Application Notes: Bioimaging
1. Seed the cells in appropriate culture medium at ~10,000 cells per well in an 96-well Imaging Plate and culture overnight.
2. Remove the culture medium from the wells, and fix the cells by adding 100 myl of Fixation Buffer to each well. Incubate for 10 minutes at room temperature (RT).
3. Remove the fixative from the wells, and permeabilize the cells using either 90% methanol, or Triton™ X-100: a. Add 100 myl of -20°C 90% methanol to each well and incubate for 5 minutes at RT. OR b. Add 100 myl of 0.1% Triton™ X-100 to each well and incubate for 5 minutes at RT.
4. Remove the permeabilization buffer, and wash the wells twice with 100 myl of 1× PBS.
5. Remove the PBS, and block the cells by adding 100 myl of to each well. Incubate for 30 minutes at RT.
6. Remove the blocking buffer and add 50 myl of the optimally titrated primary antibody (diluted in Stain Buffer) to each well, and incubate for 1 hour at RT.
7. Remove the primary antibody, and wash the wells three times with 100 myl of 1× PBS.
8. Remove the PBS, and add the second step reagent at its optimally titrated concentration in 50 myl to each well, and incubate in the dark for 1 hour at RT.
9. Remove the second step reagent, and wash the wells three times with 100 myl of 1× PBS.
10. Remove the PBS, and counter-stain the nuclei by adding 200 myl per well of 2 myg/ml Hoechst 33342 in 1× PBS to each well at least 15 minutes before imaging.
11. View and analyze the cells on an appropriate imaging instrument.

Background: Initiation of eukaryotic translation involves a series of reactions mediated by multiple eukaryotic initiation factors (eIFs). However, one member of this family, eIF-5a, may have multiple protein functions. eIF-5a was originally identified as an initiation factor due to its binding of ribosomes, and its stimulation of methionyl-puromycin. Regulation of initiation may not be the major function of eIF-5a, since it functions as a targeting protein for the HIV protein, Rev, and the T-cell leukemia virus type 1 protein, Rex. In Xenopus oocytes, eIF-5a interacts with the nucleoporins Nup214, Nup153, Nup98, and Nup62, and is required for Rev-NES interaction with exportin1. These interactions may be involved with eIF-5a nuclear export of Rev protein, and eIF-5a requirement for Rev-mediated viral RNA export. eIF-5a is ubiquitously expressed, and is the only known eukaryotic protein that contains the post-translationally formed hypusine residue. Modification of eIF-5a with hypusine is coupled to cell proliferation, and disruption of this residue in yeast eIF-5a is lethal. Thus, eIF-5a may be an important nuclear transport protein with conserved function in many species.
