Adenoviral Expression of IRF6

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adenovirus production followed the AdEasy protocol56 (link). Briefly, human IRF6 cDNA from pCMV-SPORT6-IRF6 plasmid was cloned into pAdTrack-CMV vector (Agilent Technologies) at Xho I and Xba I restriction enzyme sites. The AdIRF6 adenovirus expression plasmid was generated from recombination between pAdEasy-1 vector and pAdTrack-CMV-IRF6 in BJ5183 competent cells (Agilent Technologies). AdIRF6 plasmid (40 μg) was linearized with Pac I restriction enzyme and subsequently transfected into AD293 cells using Lipofectamine 2000 reagent (Invitrogen) according to the manufacturer’s protocol for adenovirus packaging. Adenoviruses were harvested at 14 to 20 days after transfection.

Adenoviral Transduction of HER2 Mutants

Check if the same lab product or an alternative is used in the 5 most similar protocols
Plasmid #16259 (human HER2, V654E) and plasmid #16258 (human HER2, K753M) were purchased from Addgene and sequenced. Both plasmids were originally in the vector pcDNA3 with 5’ and 3’ HindIII cloning sites. They were cloned into the HindIII site of pAdTrack-CMV (He et al., 1998 (link)). These constructs were recombined with pAdEasy in BJ5183 competent cells (Agilent Technologies). Subsequently, Adenovirus5 (Ad5) was produced and titrated using standard methods. Western blot experiments were used to verify the activity of the constructs, as described in the Results section. The GFP virus was purchased from Vector Biolabs. All viral protocols were reviewed by the URMC Biosafety committee to ensure the safety of staff and the environment.

Recombinant Adenovirus Production

Check if the same lab product or an alternative is used in the 5 most similar protocols
The AdEasy Adenoviral vector system (Agilent Technologies, Santa Clara, CA, USA Catalog #240031 and #240032) was used to generate recombinant adenoviruses. Full length cDNA of human WT or S75Y RagC was subcloned into the pshuttle vector, pshuttle–IRES–hrGFP under the control of CMV promoter. The constructed vector was co-transformed into BJ5183 competent cells (Agilent Technologies, Santa Clara, CA, USA) together with pAdEasy-1, the viral DNA plasmid. Recombinant Adenovirus plasmid DNA was generated via homologous recombination and then transfected AD293 cells with lipofectamine 2000 (Thermo Fisher, Waltham, MA, USA) to produce recombinant adenoviruses, Ad:RagCWT and Ad:RagCS75Y. The Ad:GFP was used as a control.

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.
