Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 34 kDa.
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. or Tris-EDTA buffer ( PH8.0).
ICC/IF Use a concentration of 1 µg/ml.


  • Function
    Catalyzes the production of spermidine from putrescine and decarboxylated S-adenosylmethionine (dcSAM). Has a strong preference for putrescine as substrate, and has very low activity towards 1,3-diaminopropane. Has extremely low activity towards spermidine.
  • Pathway
    Amine and polyamine biosynthesis; spermidine biosynthesis; spermidine from putrescine: step 1/1.
  • Sequence similarities
    Belongs to the spermidine/spermine synthase family.
    Contains 1 PABS (polyamine biosynthesis) domain.

Anti-Spermidine synthase antibody images

  • ICC/IF image of ab111884 stained MDA-MB-231 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 ab111884 at 1µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Dylight® 488 goat anti- rabbit (ab96899) IgG (H+L) preadsorbed, used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.
