Recombinant Anti-MLK3 antibody [EP1460Y] (ab51068)

Blocking buffer: 5% NFDM/TBST

Immunocytochemistry analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling MLK3 with Purified ab51068 at 1:50 dilution (3.52 µg/ml). Cells were fixed in 100% Methanol and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 μg/ml). Goat anti rabbit IgG (Alexa Fluor® 488,ab150077) was used as the secondary antibody at 1:1000 (2 μg/ml) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Lanes 1- 2: Merged signal (red and green). Green - ab51068 observed at 105 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

 ab51068 was shown to react with MLK3 in wild-type A549 cells in western blot. Loss of signal was observed when knockout cell line ab267169 (knockout cell lysate ab257519) was used. Wild-type A549 and MAP3K11 knockout A549 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. ab51068 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 5000 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.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: MLK3 knockout HAP1 cell lysate (20 µg)
Lane 3: A431 cell lysate (20 µg)
Lane 4: HeLa cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab51068 observed at 105 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab51068 was shown to specifically react with MLK3 when MLK3 knockout samples were used. Wild-type and MLK3 knockout samples were subjected to SDS-PAGE. ab51068 and ab8245 (loading control to GAPDH) were diluted 1/5000 and 1/1000 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 1/10000 dilution for 1 hour at room temperature before imaging.
