- Experimental Notes
ABIN654696 reveals a protein of the expected molecular weight in lysates of 293T and in Flp-In T-Rex HEK293 cells harboring Tet inducible Fusion SPT upon Tet induction. It also showed the expected size protein band in HEK-293 cells transiently transfected with ORMDL1/2 or 3 tagged recombinant plasmids and with the purified ORMDL-GFPs (GFP fusion proteins run higher due to the tag).
ABIN654696 did not detect recombinant ORMDL3-HA in total lysates from Jurkat cells stably expressing ORMDL3-HA.
ORMDL protein bands are visible in the positive samples and were significantly decreased upon knockdown using ORMDLs siRNAs. siRNA knockdown showed reduced expression of ORMDLs in uninduced and Tet induced fusion SPT cells as compared to the respective controls.
In Jurkat cells the signal is very week but longer exposure reveals the protein at the expected molecular weight. With 293T cells we see a stronger band just above 21kDa. This band was absent in Jurkat cells and in the purified proteins.
