H3 | Histone H3 (rabbit antibody) (nuclear marker)

PRODUCT INFORMATION IN PDF

5 µl of 15μg/µl Solanum lycopersicum protein saturated in 8M urea were separated on 15% SDS-PAGE and blotted for 1hour to 0.2 µm nitrocellulose at 100V using wet transfer system. Blots were blocked with 0.5% cold fish gelatin for 1hr at room temp with agitation. Blot was incubated in the primary antibody (anti-H3) at a dilution of 1:2500 for an hour at RT with agitation. The blots were washed with 3X 15min TBS-TT at RT with agitation. Blots as incubated in the secondary antibody, fluorescent antibody (AS12 2460, Agrisera) 1:5000 dilution for 30min at RT with agitation and washed 1X with TBSTT for 15min, 1X with TBST for 15min before scanning with the ODyssey IRD scanner.

Immunocytochemical assays were performed according to the method described earlier (Rybaczek and Maszewski 2006). Excised apical parts of Vicia faba roots (1.5 mm long) were fixed for 45 min (18°C) in PBS-buffered 3.7% paraformaldehyde, washed several times with PBS and placed in a citric acid-buffered digestion solution (pH 5.0; 37°C for 45 min) containing 2.5% pectinase (Fluka), 2.5% cellulase (Onozuka R-10; Serva) and 2.5% pectoliase (ICN). After removing the digestion solution, root tips were washed 3 times in PBS, rinsed with distilled water and squashed onto Super Frost Plus glass slides (Menzel-Gläser). Air-dried slides were pretreated with PBS-buffered 5% BSA at 20°C for 50 min and incubated overnight in a humidified atmosphere (4°C) with rabbit antibody raised against H3 histone (Agrisera), dissolved in PBS containing 1% BSA (at a dilution of 1:50). Following incubation, slides were washed 3 times with PBS and incubated for 1 h (18°C) with Agrisera secondary goat anti-rabbit IgG DyLight®488 antibody (AS09 633, 1:1000). Nuclear DNA was stained with 4’,6-diamidino-2-phenyl-indole (DAPI, 0.4 μg/ml; Sigma-Aldrich). Following washing with PBS, slides were air dried and embedded in Vectashield Mounting Media for Fluorescence (Vector Laboratories). Observations were made using Optiphot-2 fluorescence microscope (Nikon) equipped with B-2A filter (blue light; λ ≈ 495 nm) for DyLight-conjugated antibodies and UV-2A filter (UV light; λ ≈ 365 nm) for DAPI. All images were recorded at exactly the same time of integration using DXM 1200 CCD camera.
