Our Abpromise guarantee covers the use of ab71700 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
IHC-P 1/50 - 1/100.
WB 1/1000. Detects a band of approximately 48 kDa (predicted molecular weight: 43 kDa).Can be blocked with SPHK1 peptide (ab187382).

There are two known isoforms of this protein, one predicted around 43 kDa and the other around 51 kDa.



  • All lanes : Anti-SPHK1 antibody (ab71700) at 1/1000 dilution

    Lane 1 : 293 cell lysate
    Lane 2 : HepG2 cell lysate
    Lane 3 : HUVEC cell lysate
    Lane 4 : Raji cell lysate
    Lane 5 : C6 cell lysate
    Lane 6 : C2C12 cell lysate

    Lysates/proteins at 35 µg per lane.

    All lanes : HRP-conjugated goat anti-rabbit IgG (H+L) at 1/5000 dilution

    Predicted band size: 43 kDa

  • Immunohistochemical staining of SPHK1 in Human hepatocarcinoma tissue sections (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections) with ab71700 at a dilution of 1/25. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hours 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 ab71700 stained HeLa cells. The cells were 4% formaldehyde fixed (10 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 (ab71700, 5µg/ml) overnight at +4°C. 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.

  • Anti-SPHK1 antibody (ab71700) at 1/500 dilution + Lysate prepared from human MDA MB 231 cells at 15 µg

    HRP-conjugated donkey polyclonal to rabbit IgG at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 43 kDa
    Observed band size: 48,52 kDa (why is the actual band size different from the predicted?)

    Exposure time: 5 minutes

  • Anti-SPHK1 antibody (ab71700) at 1/1000 dilution + mouse kidney tissue lysate at 12.5 µg

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

    Predicted band size: 43 kDa
    Observed band size: 48 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 52 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.
