Our Abpromise guarantee covers the use of ab40693 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 43 kDa (predicted molecular weight: 43 kDa).|
|ICC/IF||Use a concentration of 5 µg/ml.|
An additional band at 41 kDa is seen in Jurkat nuclear lysate. This possibly corresponds to TIAR, a closely related protein of TIA1, found mainly in the nucleus.
ab40693 stained in MCF7 cells. Cells were fixed with 4% paraformaldehyde (10min) at room temperature and incubated with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% triton for 1h at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab40693 at 1µg/ml and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control) at 1/1000 dilution overnight at +4°C. The secondary antibodies were ab150120 (pseudo-colored red) and ab150081 (colored green) used at 1 µg/ml for 1 hour at room temperature. DAPI was used to stain the cell nuclei (colored blue) at a concentration of 1.43 µM for 1hour at room temperature.
ICC/IF image of ab40693 stained HeLa (human epithelial cell line from cervix adenocarcinoma) cells. The cells were fixed in 4% formaldehyde for 10 minutes and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab40693, 5 µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1 hour. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1 hour. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 µM.
ab40693 staining TIA1 in human lymphoma tissue sections by IHC-P (formaldehyde-fixed paraffin-embedded sections). Tissue samples were fixed with formaldehyde and blocked with peroxidase for 5 minutes followed by a protein block for 10 minutes at 20°C . Antigen retrieval was by heat mediation in target retrieval solution. Samples were incubated with primary antibody 1/2000 for 45 minutes at 20°C. An HRP-conjugated Goat polycolonal to rabbit IgG was used as secondary antibody. The image shows clean predominantly nuclear staining.
