Plasmids pBK-CMV expression vector. Expresses the native untagged cDNA of WFDC1 in mammalian cells (A kind gift of Xxxxx Xxxxxx, Xxxxxxxxxx, USA) pMIGR1-eGFP Retroviral plasmid pMIGR1-eGFP encodes a multiple cloning site (MCS) upstream of enhanced green fluorescent protein (eGFP) separated by an internal ribosome entry site (IRES). The gene of interest is cloned into the MCS and the IRES ensures bicistronic expression of the eGFP reporter gene independently of the gene of interest. Figure 2.1 plasmid maps of pBK-CMV and MIGR1

Plasmids. The hDAGLa plasmid was constructed as described before.[38] Briefly, full length human cDNA of hDAGL-a was pur- chased from Biosource and cloned into mammalian expression vector pcDNA3.1, containing genes for ampicillin and neomycin re- sistance. A FLAG-linker was made from primers and cloned into the vector at the C-terminus of hDAGL-a. The plasmid was grown in XL-10 Z-competent cells and prepped (Maxi Prep, Qiagen). The sequences were confirmed by sequence analysis at the Leiden Genome Technology Centre. Transfection. HEK293T cells were grown to & 70 % confluency in 15 cm dishes. Prior to transfection, culture medium was refreshed (15 mL). A 3:1 (m:m) mixture of polyethyleneimine (PEI, 60 mg/well) and plasmid DNA (20 mg/well) was prepared in serum free culture medium and incubated for 10 min at rt. Transfection was per- formed by dropwise addition of the PEI/DNA mixture (2 mL/well) to the cells. 24 h post-transfection, the medium was refreshed and after 48 h cells were harvested. U2OS_ABHD6-GFP stable expression. Full-length human cDNA of ABHD6 (Source Bioscience) was cloned into mammalian expression vector pcDNA3.1, containing genes for ampicillin and neomycin re- sistance. The inserts were cloned in frame with a C-terminal FLAG- and GFP-tag. Plasmids were isolated from transformed XL-10 Z- competent cells (Maxi Prep kit: QiaGen) and sequenced at the Leiden Genome Technology Center. Sequences were analyzed and verified (CLC Main Workbench). One day prior to transfection U2OS cells were seeded to a 6 xxxxx plates (& 0.5 million cells/well). Prior to transfection, culture medium was aspirated and a minimal amount of medium was added. A 3:1 (m m@1) mixture of polyethy- leneimine (PEI) (3.75 mg/well) and plasmid DNA (11.25 mg/well) was prepared in serum free culture medium and incubated (15 min, RT). Transfection was performed by dropwise addition of the PEI/ DNA mixture to the cells. After 24 h, transfection efficiency was de- termined by fluorescence microscopy and transfection medium was exchanged for selection medium containing 800 mg mL@1 G418. 48 h Post-transfection single cells were seeded to 96 xxxxx plates in 100 mL selection medium. After 14 days, plates were in- spected for cell growth, clones were checked for ABHD6-GFP ex- pression by fluorescence microscopy (GFP channel). From here on, cells were grown in maintenance medium containing 400 mg mL@1 G418, and expanded in 12- and 6-xxxxx plates and 10 cm dishes. Inhibitor treatment. The medium was ...
