  • Anti-GPCR GPR49 antibody (ab71225) at 1/1000 dilution + K562 cell line lysates at 35 µg

    HRP goat-anti rabbit (H+L) at 1/5000 dilution

    Predicted band size : 100 kDa
    Observed band size : 100 kDa
    Additional bands at : 55 kDa,60 kDa,72 kDa. We are unsure as to the identity of these extra bands.

    Incubation time was overnight at 4°C. Blocking/Dilution buffer: 5% NFDM/TBST.

  • Immunohistochemical staining of GPCR GPR49 in Human brain tissue sections (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections) with ab71225 at a dilution of 1/25. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hour at 38°C. Antigen retrieval was heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody (1/25) for 1 hours at 37°C. A HRP-conjugated goat anti-rabbit polyclonal (ready to use) was used as the secondary antibody.

  • ICC/IF image of ab71225 stained SKNSH cells. The cells were 4% PFA fixed (10mins) 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 (ab71225, 5µg/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 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.

Thank you for contacting us.

You can choose any of these, all of them should work in IHC-P/ human tissues.

We unfortunately haven't tested these antibodies in particular with intestine tissue sections however as these are tested posit...
