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.

Western blot - Anti-hnRNP A1 (citrulline R97) antibody [EPR20176] (ab208028)

Lanes 1-2 & 4 : Anti-hnRNP A1 (citrulline R97) antibody [EPR20176] (ab208028) at 1/5000 dilution
Lane 3 : Anti-hnRNP A1 (citrulline R97) antibody [EPR20176] (ab208028) at 1/1000 dilution

Lanes 1 & 3 : Empty vector (vector control) transfected HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen), whole cell lysate
Lane 2 : HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) whole cell lysate transfected with GFP-tagged PADI2 and treated with 10 mM CaCl2 for 2 hours, followed by 10 uM Ionomycin for 2 hours
Lane 4 : HEK-293T (human epithelial cell line from embryonic kidney tranformed with large T antigen) whole cell lysate transfected with GFP- tagged PADI4 and treated with 10 mM CaCl2 for 2 hours, followed by 10 uM Ionomycin for 2 hours

Exposure time: 4 seconds

Blocking/Dilution buffer: 5% NFDM/TBST.

According to Uniprot annotation, isoform A1-A (34kD) is twenty times more abundant than isoform A1-B (39kD). PADs (including PADI2 and PADI4) are the enzymes that hydrolyze arginine to form citrulline, and this catalytic reaction also needs Ca²⁺ and ionomycin. Please refer to PMID: 26360112.
