  • Formalin-fixed, paraffin-embedded section of Human breast carcinoma stained with ab82171 at 1/50 dilution. Incubate primary antibody (ab82171) for 30 minutes at RT.
  • ICC/IF image of ab82171 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 (ab82171, 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.

Customer reviews and Q&As


Thank you for your enquiry.

I have reviewed the immunogen sequences of the DHFR antibodies we have and regrettably the alignment with the e coli amino acid sequence is very low. Therefore, we would not anticipate that these antibodies would detect the DHFR in e coli. In this case, I am sorry we are not able to offer the AbTrial.

I am sorry there are no suitable DHFR antibodies to suggest to you on this occasion.

We are happy to be able to offer custom antibody services through Epitomics, an Abcam company. This may be helpful to you. For more information about these services visit:
