GN | Gnom

KLH-conjugated peptide derived from Arabidopsis thaliana GN protein sequence, UniProt: Q42510, TAIR: At1g13980

Samples: M - Marker, A - Arabidopsis thaliana wild type, B - gnom R5 mutant, C gn:GNOM-GFP/gn:GNOM-3xHA The cell lysate was prepared from 10 A. thaliana seedlings (8-9d old). Seedlings were frozen in liq N2, then lysed with tissue lyzer, and 100 µl extraction buffer (100mM NaH2PO4 10mM Tris/HCl pH 8.0, 8M Harnstoff) was added. Total protein was denatured with 4x Laemmli buffer at 72ºC for 5min and separated on a 4-20% Mini Protean precast gel from BioRad and blotted for 4.5h to nitrocellulose using wet transfer. Blots were blocked with 5%NFDM for 1h at RT with agitation. The blot was incubated with primary antibody at a dilution of 1:1000 O/N at 4ºC in 1% NFDM in TBS-T. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once 15min and 3x 5min in TBS-T at RT with agitation. The blot was incubated using anti-rabbit IgG (HRP conjugated) from Agrisera (AS09 602) diluted 1:25 000 in 1% NFDM in TBS-T for 1h at RT with agitation. The blot was washed as above and developed for 5min with Agrisera ECLSuperBrigth Exposure time was 5 sec.
The cell lysate (GNOM-GFP/GNOM-3xHA) was prepared by grinding 1g seedlings(5-6 days old) in 1ml lysis buffer (50mM Tris-HCl pH7.5, 150mM Nacl+2mM EDTA+1% Tx 100 + Protease inhibitors). Total protein was denatured with 4x Laemmli buffer at 95C for 5min.

Nitrocellulose membrane with pore size 0.45 µm is recommended as well as TBS-T as antibody incubation buffer. 

This antibody is also recognzing recombinant GN fused to GFP.
