      • For tet-induction of SPT expression add 2µg/ml tetracyline.
      • For ORMDLs siRNA knockdown transfect a mix of 0.8ml optiMEM (each siRNA 7.5µl from 20µM stock diluted in 0.4ml optiMEM + 15µl lipofectamine in 0.4ml optiMEM) with a final concentration of50nM of ORMDL1 (Dharmacon, 94101), ORMDL2 (Dharmacon, 29095), and ORMDL3 (Dharmacon, 94193) siRNA each into Flp-In T-Rex HEK293 cells (2.2ml optiMEM) harboring tet-inducible Fusion serine palmitoyl transferase (LCB2a-ssSPTa-LCB1) SPT using lipofectamine 2000 (ThermoFisher Scientific, 11668019, lot 1959316 or 1992885) following the manufacturer´s instructions into a final volume of 3ml. After 10h incubation, add complete DMEM media with 2µg/ml tetracycline and incubate for 46h.
    • Wash cells twice with ice-cold PBS.

    • Wash membrane with deionized water and then 4x for 10min with TBST.
    • Reveal protein bands using Western Lightning Plus-ECL (PerkinElmer, NEL105001EA, lot 203-17431) on a Kodak X-OMAT 2000A processor using Radiomat LS 7980052 films (MidSci).
    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.
