Generating Stable SNAT2 Knockdown in Corneal Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Plasmid expressing shRNA against human SNAT2 (Sigma-Aldrich, TRCN0000020239 and TRCN0000020241) and MISSION® pLKO.1-puro Non-Target shRNA Control Plasmid DNA (Sigma-Aldrich, SHC016)) were purchased from Sigma-Aldrich. HEK 293T cells (150 mm dishes, 50% confluency) (ATCC, CRL-3216) were transfected with 12.5 μg shRNA expressing vector: 8 μg viral packaging plasmid (psPAX2 (Addgene,12260)): 4.5 μg viral envelope plasmid (pMD2.G (Addgene,12259)) ratio with X-tremeGENE™ 9 DNA Transfection Reagent (Roche, 6365779001) according to the manufacturer’s instructions. After transfection, cells were maintained in corneal growth media which was collected after 24, 48 and 72 h and filtered through 0.45 μM filter. The filtrate was diluted with the corneal growth media (4:1 ratio) supplemented with Hexadimethrine bromide (Sigma-Aldrich, H9268) at 10μg/mL and added to the corneal cells for 12 h followed by 12 h in the growth media without viral particles. The procedure was repeated once more and cells were allowed to recover one day in the growth media. After this, cells were subcultured and grown in media containing 1 μg/mL puromycin. After 3–4 days of the selection with puromycin cells were used for experiments. Knockdown efficiency was verified by Western blot analysis.

Megalin Mini Receptor Plasmid Constructs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Megalin mini receptor (mMeg) was generated from a human kidney cDNA library (Marzolo et al., 2003 (link); Farfán et al., 2013 (link)). Plasmids for phosphomimetic mMeg (mMeg S170D), non-phosphorylatable mMeg (mMeg S170A) and mMeg lacking the ectodomain (Meg0) were described previously (Yuseff et al., 2007 (link); Marzolo and Farfán, 2011 (link)). mCherry-Rab11 was kindly provided by Dr. Alexis Gautreau (Derivery et al., 2009 (link)). Human OCRL1-EGFP was described before (Vicinanza et al., 2011 (link)). Plasmids for short hairpin RNAs were MISSION® pLKO.1-puro Non-Target shRNA Control Plasmid DNA (Sigma-Aldrich), pLKO vectors purchased from Open Biosystems (shOCRL1 5′- GCC​AAG​TAT​AAG​AAA​GTT​CAA -3′ and shAPPL1 5′- GCA​TTG​TTA​GAA​CCT​CTA​CTT-3′). The primers used in quantitative PCR reactions were as follows: megalin forward, 5′- CTG​CTC​TTG​TAG​ACC​TGG​GTT​C -' 3; megalin reverse, 5′- TCG​GCA​CAG​CTA​CAC​TCA​TAA​C -3; glyceraldehyde-3-phosphate dehydrogenase forward, 5′- TCA​AGG​CTG​AGA​ATG​GGA​AG -`3; glyceraldehyde-3-phosphate dehydrogenase reverse, 5′- AGC​AGA​AGG​GGC​AGA​GAT​G -`3.

Plasmid expressing shRNA against OPA1 (Sigma-Aldrich, TRCN0000091111) and MISSION® pLKO.1-puro Non-Target shRNA Control Plasmid DNA (Sigma-Aldrich, SHC016)) were purchased from Sigma-Aldrich. HEK 293T cells (150 mm dishes, 50% confluency) (ATCC, CRL-3216) were transfected with 12.5 μg shRNA expressing vector: 8 μg viral packaging plasmid (psPAX2 (Addgene,12260)): 4.5 μg viral envelope plasmid (pMD2.G (Addgene,12259)) ratio with X-tremeGENE 9 DNA Transfection Reagent (Roche, 6365779001) according to the manufacturer’s instructions. Media was collected after 24, 48 and 72 hours and filtered through 0.45 μM filter. The filtrate was diluted with the full media (1:5 ratio) supplemented with Hexadimethrine bromide (Sigma-Aldrich, H9268) at 10μg/ml and added to MEFs for 12 h followed by 12 h in the growth media without viral particles. The procedure was repeated once more and cells were allowed to recover one day in the growth media. After this, cells were subcultured and grown in media containing 30 μg/ml puromycin (Thermo Fisher Scientific, A1113803). After 3–4 days of the selection with puromycin cells were used for experiments. Knockdown efficiency was verified using Western blot analysis.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
