Anti-Neurofibromin antibody [EPR22989-68] - BSA and Azide free

• WB

Lab

Western blot - Anti-Neurofibromin antibody [EPR22989-68] - BSA and Azide free (AB260004)

This data was developed using the same antibody clone in a different buffer formulation (ab238142).

Lanes 1-3 : Merged signal (red and green). Green - ab238142 observed at 319 kDa. Red - loading control ab7291 observed at 50 kDa.

ab238142 Recombinant Anti-NF1 antibody [EPR22989-68] was shown to specifically react with NFIB in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264725 (knockout cell lysate ab258533) was used. Wild-type and NF1 knockout samples were subjected to SDS-PAGE. ab238142 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

This data was developed using the same antibody clone in a different buffer formulation (ab238142). Anti-NF1 antibody [EPR22989-68] (ab238142) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab238142 was shown to bind specifically to NF1. A band was observed at 180-270 kDa in wild-type MCF7 cell lysates with no signal observed at this size in NF1 knockout cell line. To generate this image, wild-type and NF1 knockout MCF7 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Western blot - Anti-Neurofibromin antibody [EPR22989-68] - BSA and Azide free (AB260004)

ab238142 was shown to specifically react with Neurofibromin in wild-type HAP1 cells as signal was lost in Neurofibromin knockout cells. Wild-type and Neurofibromin knockout samples were subjected to SDS-PAGE. ab238142 and ab129002 (Rabbit anti-Vinculin loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/5000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD^® ChemiDoc™ MP instrument using the ECL technique. Lysate should be made freshly and used in WB immediately to minimize protein degradation. Degraded fragment(250 KD) observed is consistent with what has been described in the literature (PMID : 30131853, PMID : 30408279).

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

Exposure time : 26 seconds.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab238142).
