Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP)
developed using the ECL technique
Predicted band size : 42 kDa
Observed band size : 42 kDa
Additional bands at : 70 kDa. We are unsure as to the identity of these extra bands.
Immunoprecipitation - Anti-GNAQ antibody (ab75825)
GNAQ was immunoprecipitated using 0.5mg HepG2 whole cell extract, 5µg of Rabbit polyclonal to GNAQ and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
The antibody was incubated under agitation with Protein G beads for 10min, HepG2 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab75825.
Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
Band: 42kDa: GNAQ.
Immunocytochemistry/ Immunofluorescence - GNAQ antibody (ab75825)
ICC/IF image of ab75825 stained HepG2 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab75825, 5µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% methanol fixed (5 min) Hek293, HepG2 and MCF7 cells at 5µg/ml, and in 4% PFA fixed (5 min) HeLa, Hek293, HepG2 and MCF7 cells at 5µg/ml.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - GNAQ antibody (ab75825)
IHC image of G protein alpha q staining in human colon formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab75825, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
