1_38F3_PURE_Fibrillarin_Antibody_1_WB_112817
Western blot analysis of cell lysates from A549, HEL (human), UMR106 (rat) and Raw264.7 (mouse) cells using Fibrillarin mouse primary antibody (clone 38F3, 1:1000 dilution) and HRP Goat anti-mouse secondary antibody (Cat. No. 405306, 1:3000 dilution). Direct-Blot™ HRP anti-β-actin (Cat. No. 643807) was used as a loading control (1:8000 dilution).

    Total lysates (15 µg protein) from 293T and 293T/Fibrillarin CRISPR/Cas9 knockdown (KD) cells were resolved by electrophoresis (4-20% Tris-Glycine gel), transferred to nitrocellulose, and probed with 1:500 diluted (1ug/mL) purified anti-Fibrillarin antibody, clone 38F3 (upper) or 1:3000 diluted anti-GAPDH (poly6314, Cat. No. 631401) antibody (lower). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated to HRP (Cat. No. 405306) for anti-Fibrillarin antibody, and a donkey anti-rabbit IgG Antibody conjugated to HRP (Cat. No. 406401) for GAPDH. Lane M: MW ladder.

    Human HEK293 cell stained with mouse monoclonal antibody to fibrillarin 38F3 (green). DNA is stained with Hoechst.
  • 4_38F3_PURE_Fibrillarin_Antibody_4_WB_010620
    Western blot of purified anti-Fibrillarin antibody (clone 38F3). Lane 1: Molecular weight marker; Lane 2: 20 µg of Drosophila S2 (embryonic) cell lysate. The blot was incubated with a 1:500 dilution of the primary antibody overnight at 4°C, followed by incubation with HRP-labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.
  • 5_38F3_PURE_Fibrillarin_Antibody_5_ICC_010620
    ICC staining of anti-Fibrillarin antibody (clone 38F3) on Drosophila S2 cells. The cells were fixed with 4% PFA, permeabilized with a buffer containing 0.1% Triton X-100 and 0.25% BSA, and blocked with 2% normal goat serum and 0.02% BSA. The cells were then incubated with a 1:500 dilution of the primary antibody overnight at 4°C, followed by incubation wit 2.5 µg/mL of Alexa Fluor® 647 goat anti-mouse IgG (Cat. No. 405322) for one hour at room temperature. Nuclei were counterstained with DAPI. The right image shows costaining with Flash Phalloidin™ Green 488 (Cat No. 424201). The images were captured with a 60X objective. Scale bar: 20 µm

Description

Nop1p was originally identified as a nucleolar protein of bakers yeast, S. cerevisiae (accession P15646). The Nop1p protein is 327 amino acids in size (34.5kD), is essential for yeast viability, and is localized in the nucleoli. It is now known to be part of the small subunit processome complex, involved in the processing of pre-18S ribosomal RNA. Nop1p is the yeast homologue of a protein apparently found in all eukaryotes and archea generally called fibrillarin. Fibrillarin/Nop1p is extraordinarily conserved, so that the yeast and human proteins are 67% identical, and the human protein can functionally replace the yeast protein. This means that suitably cross-reactive antibodies to Nop1p/fibrillarin, like MCA-38F3, can be used to reveal nucleoli and study fibrillarin/Nop1p in all eukaryotes and archea tested to date.

Application

WB - Quality tested
ICC, KO/KD-WB  - Verified

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1.0 - 0.5 µg per mL (dilution 1:500 - 1:1000). For immunocytochemistry, a dilution range of 1:500 (mammalian), and 1:1000 - 1:5000 (yeast) is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Reactivity to Drosophila was only verified with the purified format.

This antibody is useful for immunoblotting (WB), immunofluorescence (ICC) and immunocytochemistry.

*Predicted MW = 34 kD

Additional Product Notes

For Western blotting, the suggested use of this reagent is 1:500-1:2000 dilution in Drosophila and 1:500-1:1000 dilution in other species. For immunocytochemistry, a dilution range of 1:500 (mammalian), 1:100 - 1:500 (Drosophila) and 1:1000 - 1:5000 (yeast) is recommended.
