Flow Cytometry (Intracellular) - Anti-RhoA antibody [EPR18134] - Low endotoxin, Azide free (AB219371)

Intracellular flow cytometric analysis of 4% paraformaldehyde-fixed HeLa (Human epithelial cells from cervix adenocarcinoma) cells labeling RhoA with ab187027 at 1/200 dilution (red) compared with a rabbit monoclonal IgG isotype control (ab172730; black) and a unlabeled control (cells without incubation with primary antibody and secondary antibody; blue). Goat anti rabbit IgG (FITC) at 1/500 dilution was used as the secondary antibody.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab187027).

Immunofluorescent analysis of 4% paraformaldehyde-fixed 0.1% Triton X-100 permeabilized Jurkat (Human T cell leukemia cells from peripheral blood) cells labeling RhoA with ab187027 at 1/150 dilution followed by Goat anti-rabbit IgG (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on Jurkat cell line is observed. The nuclear counter stain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution and ab150120 (AlexaFluor^®594 Goat anti-Mouse secondary) at 1/1000 dilution (red).
The negative controls are as follows :
1. ab187027 at 1/150 dilution followed by ab150120 (AlexaFluor^®594 Goat anti-Mouse secondary) at 1/1000 dilution.
2. ab7291 (anti-Tubulin mouse mAb) at 1/1000 dilution followed by ab150077 (Alexa Fluor^®488 Goat Anti-Rabbit IgG H&L) at 1/1000 dilution.

Western blot - Anti-RhoA antibody [EPR18134] - Low endotoxin, Azide free (AB219371)

Lanes 1 - 3 : Merged signal (red and green). Green - ab187027 observed at 22 kDa. Red - loading control, ab9484, observed at 37 kDa.

ab187027 was shown to specifically react with RhoA in wild-type Hek293T cells as signal was lost in RHOA knockout cells. Wild-type and RHOA knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. ab187027 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab187027).

This data was developed using the same antibody clone in a different buffer formulation (ab187027).

Lanes 1- 4 : Merged signal (red and green). Green - ab187027 observed at 21 kDa. Red - Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) observed at 50 kDa.

ab187027 was shown to react with RhoA in wild-type HEK-293T cells in western blot. Loss of signal was observed when knockout cell line ab266592 (knockout cell lysate ab257637) was used. Wild-type HEK-293T and RHOA knockout HEK-293T 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. ab187027 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) overnight at 4°C at a 1 in 5000 dilution and a 1 in 20000 dilution respectively.
