Clathrin Light Chain Mutant Construction

Check if the same lab product or an alternative is used in the 5 most similar protocols
Hoechst 33342 and Pitstop 2 were purchased from Sigma-Aldrich. Pitstop 2 were dissolved in dimethyl sulfoxide (DMSO) according to the manufacturer’s instructions. The lipophilic dyes DiO and DiD were purchased from Biotium. The fluorescent dyes Alexa Fluor 647 and Alexa Fluor 488 phalloidin were purchased from Invitrogen. anti-β-tubulin was purchased from Abcam (USA). peroxidase-conjugated affinipure goat anti-rabbit IgG were purchased from proteintech (USA).
Using the primers listed in Table 1, the full-length CLCs were constructed in vectors including pcDNA3.1-flag, pEGFP-N3, and pmDsRed-C1 (Invitrogen). Site-directed mutants, including EaCLCa-W119R and EaCLCb-W122R, were all subcloned into the pEGFP-N3, pmDsRed-C1 and pcDNA3.1-flag vectors using specific primers (Table 1) and the Fast Mutagenesis Kit V2 (Vazyme). Tryptophan (W)119 of CLCa and W122 of CLCb were both replaced with arginine(R). In addition, the pEGFP-Rab5 vector was maintained in our laboratory. The constructed plasmids were confirmed by sequencing.

AMPK-α2 Regulation by Src and FAK

Check if the same lab product or an alternative is used in the 5 most similar protocols
Homo Sapiens AMPK-α2 cDNA was a gift from Stefan Riedl (Sanford Burnham Prebys Medical Discovery Institute, originally from Dharmacon, Lafayette, CO), and was constructed into pcDNA3.1-HA and pEGFP-N3 (Invitrogen) vectors to express HA- or GFP-tagged AMPK-α2. AMPK-β2-Flag (Addgene plasmid # 40603) and AMPK-γ1-HA (Addgene plasmid # 40605) (26 ) were gifts from Harvey Lodish (MIT, Cambridge, MA). Wild-type (WT) Src, kinase-dead (KD) Src (K295N), active Src (Y527F), HA-FAK and various FAK mutants have been described (27 (link)). Phospho-mimetic mutant AMPK-α2-Y179E and phosphorylation-resistant mutant AMPK-α2-Y179F were created by using the Quick Change Mutagenesis Kit (Agilent Technologies, Santa Clara, CA). Recombinant AMPK-α/β/γ proteins were from EMD Millipore; recombinant GST-tagged active Src kinase was from (R&D Systems Inc., Minneapolis, MN).

Overexpression of CCN2 and AKT3 via miR-610

Check if the same lab product or an alternative is used in the 5 most similar protocols
For ectopic expression of CCN2 and AKT3, CCN2 open reading frames (ORFs) and AKT3 ORFs with a 3′-untranslated region (UTR) were amplified using polymerase chain reaction (PCR) and subcloned into pEGFP-N3 (Invitrogen Life Technologies). To construct a luciferase reporter vector, the CCN2 and AKT3 3′-UTR fragment containing putative binding sites for miR-610 were amplified using PCR and cloned downstream of the luciferase gene in the pGL3-luciferase reporter plasmid (Promega Corporation, Madison, WI, USA). The miR-610 mimics, negative control, and miR-610 inhibitor were purchased from Genecopoeia (Rockville, MD, USA). The transfections were performed with Lipofectamine 2000 reagent (Invitrogen Life Technologies).

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.
