Our Abpromise guarantee covers the use of ab62302 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
ELISA Use at an assay dependent concentration.
WB Use a concentration of 5 µg/ml. Detects a band of approximately 66 kDa (predicted molecular weight: 66 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.
ICC/IF Use a concentration of 5 µg/ml.


  • Function
    Transporter for the intake of folate. Uptake of folate in human placental choriocarcinoma cells occurs by a novel mechanism called potocytosis which functionally couples three components, namely the folate receptor, the folate transporter, and a V-type H(+)-pump.
  • Tissue specificity
    Placenta, liver, and to a much smaller extent, in lung.
  • Sequence similarities
    Belongs to the reduced folate carrier (RFC) transporter (TC 2.A.48) family.
  • Post-translational
    Heavily glycosylated.

  • SLC19A1 antibody (ab62302) at 5.0µg/ml (in 5% skim milk / PBS buffer) + Jurkat cell lysate at 10 µg

    HRP conjugated anti-Rabbit IgG at 1/50000 dilution

    Predicted band size : 66 kDa
    Observed band size : 66 kDa
    Gel concentration: 8%
  • ICC/IF image of ab62302 stained MCF7 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 (ab62302, 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 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.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human kidney tissue labelling SLC19A1 with ab62302 at 4-8µg/ml. Arrows indicate positively stained epithelial cells of the renal tubule. Magnification: 400X.
