  • Tissue specificity
    Widely expressed in normal and in cancer cells.
  • Involvement in disease
    Symptomatic deficiency in lactate transport
    Familial hyperinsulinemic hypoglycemia 7
  • Sequence similarities
    Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 54 kDa
    Observed band size: 54 kDa
    Additional bands at: 40 kDa, 89 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 2 minutes
  • ICC/IF image of ab85021 stained HeLa cells. The cells were 4% PFA 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 (ab85021, 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. This antibody also gave a positive result in 4% PFA fixed (10 min) Hek293, HepG2 and MCF7 cells at 5µg/ml, and in 100% methanol fixed (5 min) HeLa, Hek293, HepG2 and MCF7 cells at 5µg/ml.
  • IHC image of Monocarboxylic acid transporter 1 staining in human normal kidney 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 ab85021, 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.

Thank you for your reply.

I am very happy to hear that the antibody is now also working well in WB.

We would like to make the improved protocol available to other users and therefore I would like to ask you to write an Abreview for WB ( and if you would like also the other applications that you used ab85021 in).

This would help other scientist with their protocol and you would earn Abpoints (images always get you 100 extra Abpoints!)that can be redeemed as discount on future purchases or Amazon vouchers.

We appreciate your feedback very much and wish you good luck with your research.

thank you very much again for providing a free replacement of MCT1
antibody ab85021! I tried it now in flow cytometry, IHC and ICC with
quite satisfactory results. However, in Western Blot the antibody
still does not perform well. I tried really hard in several blots to
get rid of the background, but was not really successful. I went up to
10% BSA and 0.5% Tween 20 as blocking reagent, blocked over night
(4°C), incubated the antibody in blocking solution (1 h RT) and washed
in several steps for a total time of more than 4 h after seconary
antibody incubation. I also tried both nitrocellulose and PVDF
membrane. Still, the blots are background-heavy (see attachment). When
I used the secondary antibody with other primary antibodies, there was
no background at all, so this cannot be the problem.
As you can see, the expected band at 54 kDa is very faint and embedded
in a lot of background, so it is not usable at all. However, it is
frequently published that MCT1 appears at 44 kDa. The topmost band of
the three distict bands (in the red box) might be something like 41-42
kDa and might therefore be usable. When discussing this issue with my
PI, she said this might be proven if we mix the antibody with the
immunizing peptide. As the results for the other methods look OK and I
do not want to claim that the antibody is not working and ask for a
replacement yet again (and in addition, the blot shown in the Abreview
section does not resemble the data sheet, neither), my suggestion
would be to compare +/- immunizing peptide and see what bands
I would really appreciate your opinion on that subject and how we
should continue from hereon.
Best regards,

Thank you for confirming these details and for your cooperation. I contacted our in house QC department and they will have a closer look at ab85021.

I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free blocking peptide (ab97985) with the order number 1134611.

To check the status of the order please contact our Customer Service team and reference this number.

Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

I would like to aks you for your feedback after using this blocking peptide. this information is very valuable for the QC department. Thank you.

I wish you the best of luck with your research.
