General notes

Our RabMAb^® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb^® patents.
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

Immunohistochemistry (Frozen sections) - Anti-MPTX+MPTX2 antibody [EPR20920-19] (ab238123)

Immunohistochemical analysis of 4% PFA fixed 0.2% Triton X-100 permeabilized frozen mouse small intestine tissue labeling MPTX1 with ab238123 at 1/500 (1.10 µg/ml) dilution followed by ab150077 AlexaFluor^®488 Goat anti-Rabbit secondary at 1/1000 (2 µg/ml) dilution. The nuclear counterstain was DAPI (Blue). Heat mediated antigen retrieval using sodium citrate buffer (10mM citrate pH 6.0 + 0.05% Tween-20). Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody was ab150077 AlexaFluor^®488 Goat anti-Rabbit secondary at 1/1000 (2 µg/ml) dilution.

Positive staining on Paneth cells in mouse small intestine is observed (PMID: 29144463).

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution

Observed band size: 27 kDa
why is the actual band size different from the predicted?

Blocking and diluting buffer and concentration: 5% NFDM/TBST.

MPTX2 is reported to express in Paneth cells in the small intestine (PMID: 29144463).

The lysates were kindly provided by an anonymous collaborator.

ab238123 was shown to specifically react with MPTX in wild-type mouse intestine tissue as signal was lost in MPTX knockout tissue. Wild-type and MPTX knockout samples were subjected to SDS-PAGE. ab238123 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD^® ChemiDoc™ instrument using the ECL technique. Exposure time: 15 seconds.

Flow Cytometry - Anti-MPTX+MPTX2 antibody [EPR20920-19] (ab238123)

Flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized HEK-293T (human embryonic kidney epithelial cell) transfected with a flag-tagged MPTX expression construct cells labeling MPTX1 with ab238123 at 1/500 (Right panel) compared with a Rabbit monoclonal IgG (ab172730) isotype control (Left panel). A Goat anti rabbit IgG (Alexa Fluor^® 647, ab150079) at 1/2000 was used as the secondary antibody.
