Background

Nucleoporin 98 (Nup98) is a component of nuclear pore complex (NPC), which
is a large protein assembly embedded in the nuclear envelope. It is localized
on both nuclear and cytoplasmic side of NPC. This protein contains glycineleucine-phenylalanine-glycine (GLFG) amino acid repeats and plays a criticalrole in nuclear trafficking.

Nup98 plays a specific role in the RNA export.

Nup98 gene is fused to a variety of partner genes in human myeloid and T-cellmalignancies via chromosomal translocation.

This hybridoma has been

established by Prof. T. Tachibana’s Lab. at Osaka City Univ.
Properties: When injected into the cytoplasm, this antibody accumulates into thenuclear pores of HeLa cells and inhibits nuclear localization of endogenous Ran.

Fig.4 Immunofluorescene staining of Nup98 in HeLa cells with 2H10 antibodies.
Black-and-white images were obtained with mAb and DAPI. Color images represent merged imagesof mAb (green) with DAPI (magenta).
HeLa cells were cultured in a glass-bottom dish for 2 days before fixation. The cells were fixed withcold methanol (-30 C) for 30 min. After washing with PBS, all fixed samples were blocked with 1%
BSA for 2 hr at room temperature. Anti-Nup98 rat mAb 2H10 was diluted to 0.5 µg/ml in PBS. Blockedsamples were treated with these primary antibody solutions overnight at 4 C. The secondary
antibodies were 4 μg/ml of Alexa488-labelled anti-rat IgG. DNA was stained with 4',6-diamidino-2phenylindole (DAPI). Samples were washed three times with PBS between treatments.

Fig. 5. Immunofluorescene staining of Nup98 in S. pombe cells with 2H10 antibody.
Black-and-white images were obtained with mAb and DAPI. Color images represent merged imagesof mAb (green) with DAPI (magenta). Dotted lines represent the outlines of cells. S. pombe cells
were fixed with 4% formaldehyde for 10 min, treated with 0.6 mg/ml Zymolyase 100T at 36°C for 70
min, and permeabilized with 1% Triton X-100 for 1 min. 10 µg/ml IgG solution of 2H10 were used.
Antibody 2H10 stained the nuclear periphery of S. pombe in a punctate pattern.

Fig. 6. Detection of Nup98 in S. pombe cell extracts by Western blotting with antibodies 2H10.
1 µg/ml IgG solution of 2H10 were used. Left and right lanes represent specimens from a wild typestrain and an S. pombe strain in which Nup98 was chromosomally replaced with Nup98-GFP,
respectively. S. pombe cells harvested were heated in distilled water at 95°C for 5 min, suspended in
100 mM phosphate buffer (pH 6.8), 4 M urea, 2.5% SDS, 0.05 mM EDTA, and disrupted by glass beads
using a Multi Beads Shocker (Yasui Kikai, Osaka,). The sample was clarified by centrifugation, andthe supernatant was used as the whole cell extract. First antibody was used at 0.4 ug/ml and as second
antibody, HRP-conjugated ant-rat IgG was used at 0.4 ug/ml. Numbers on the left are positions of size
marker Proteins in kDa.
