ICC/IF analysis of Tetrahymena themophila cells using GTX00693 NUP98 antibody [13C2], GTX00695 NUP98 antibody [21A10], or GTX00697 NUP98 antibody [2H10]. The open arrow indicates the micronucleus. Insets are magnified images showing the position of the micronucleus. Both clone 13C2 and 21A10 stained the macronuclear periphery of T. thermophila. 13C2 mAb was highly specific to the macronucleus. In contrast, in addition to clear macronuclear staining, clone 21A10 also stained the micronuclear periphery. This indicates that 21A10 recognizes Nups localizing to the micronucleus such as Nup308 in addition to MacNup98A. Neither could 2H10 nor 414 could stain nuclear periphery of Tetrahymena. Green : Primary antibody Violet : DAPI Dilution : 0.5 microg/ml Fixation : Cold Methanol (-30 degree C) for 30 min
