Recombinant Anti-MSH6 antibody [EPR3945] (ab92471)

Immunohistochemical staining of paraffin embedded human colon with purified ab92471 at a dilution of 1/500. A pre-diluted HRP polymer for rabbit/mouse IgG was used as the secondary antibody and the sample was counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Lanes 1- 2: Merged signal (red and green). Green - ab92471 observed at 160 kDa. Red - Anti-Vinculin antibody [VIN-54] observed at 124 kDa.

 ab92471 was shown to react with MSH6 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab255410 (knockout cell lysate ab263763) was used. Wild-type HeLa and MSH6 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab92471 and Anti-Vinculin antibody [VIN-54] overnight at 4°C at a 1 in 1000 dilution and a 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.

Lanes 1 - 4: Merged signal (red and green). Green - ab92471 observed at 160 kDa. Red - loading control, ab18058, observed at 124 kDa.

ab92471 was shown to specifically react with MSH6 in wild-type HAP1 cells. No band was observed when MSH6 knockout samples were used. Wild-type and MSH6 knockout samples were subjected to SDS-PAGE. ab92471 and ab18058 (loading control to Vinculin) were diluted at 1/1000 and 1/10 000 respectively and incubated overnight at 4°C. 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 1/10 000 dilution for 1 h at room temperature before imaging.

ab92471 staining MSH6 in wild-type HAP1 cells (top panel) and MSH6 knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab92471 at 1μg/ml and ab195889 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

Unpurified ab92471, at a 1/100 dilution, detecting MSH6 in paraffin embedded Human colonic adenocarcinoma tissue by immunohistochemistry. Detection used HRP conjugated anti rabbit antibody.

Heat mediated antigen retrieval was performed before commencing with IHC staining protocol.

Unpurified ab92471 (1/500) staining MSH6 in asynchronous HeLa cells (green). Cells were fixed in paraformaldehyde, permeabilised with 0.5% Triton X100/PBS and counterstained with DAPI in order to highlight the nucleus (red). For further experimental details please see abreview.
