Anti-NSD3 抗体 [EPR25189-8] (ab300489)

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

The expression profile and molecular weight observed are consistent with what has been described in the literature (PMID: 34615858, 26626481).

This blot was developed using a high sensitivity ECL substrate. The high-sensitivity ECL substrate used allows for the detection of proteins in the mid-femtogram range.

Lysates were freshly made and used immediately to minimize protein degradation.

Blocking / Diluting buffer: Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS.

False colour image of Western blot: Anti-NSD3 antibody [EPR25189-8] (ab300489) staining at 1/2000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red.

In Western blot, ab300489 was shown to bind specifically to NSD3. Two bands were observed at 180kDa, 85kDa in wild-type HAP1 cell lysates with no signal observed at this size in the NSD3 knockout cell line. To generate this image, wild-type and NSD3 knockout HAP1 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a PVDF-FL membrane. Membranes were blocked in Odyssey diluted in equal volume of 0.1 % TBS 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 (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

This blot was developed using a high sensitivity ECL substrate. The high-sensitivity ECL substrate used allows for the detection of proteins in the mid-femtogram range.

Lysates were freshly made and used immediately to minimize protein degradation.
Extra bands at 70 and 50 kDa observed in lane 2 may be caused by degradation during incubation.
