Characterization of DPR and TDP-43 Constructs

Check if the same lab product or an alternative is used in the 5 most similar protocols
We previously generated and characterised expression of DPR constructs for expression of GA1020, GR1136, PR1100 and AP1024 under the CMV promoter and with a C-terminal GFP-tag, using the pEGFP-N1 vector8 . To overcome the potential issue of repeat-length instability between preparations of plasmid, each individual tube of DPR construct was size-screened before use by restriction digest and agarose gel as described previously, to ensure repeat-length was correct8 . Empty pEGFP-N1 vector was used throughout as a GFP-only control. A full length TDP-43 clone (a gift from Professor Leonard Petrucelli, Mayo Clinic, Florida, USA) was used as a template for PCR using the forward primer (5′ GCTCAAGCTTATATGTCTGAATATATTCGGGTA 3′) and reverse (5′ GAGCGGATCCCTACATTCCCCAGCCAGAAGACT 3′) containing HindIII and BamHI sites respectively. After digestion the product was ligated in pmCherry-C1 (Clontech) in the same restriction sites to create the pmCherry-C1 TDP-43 WT construct. All constructs were verified by DNA sequencing.

Δ264CFTR was subcloned from pcDNA3.1 into pmCherry-C1 (Clontech, #632524) using the following primers: 5’-tagggtaccatgatcgagaacatccaatctgtta-3’ and 5’- taaacgggccctaaagccttgtatcttgca-3’. Δ27–264CFTR was subcloned from pcDNA3.1 into pmCherry-C1 (Clontech, #632524), and ΔF508-CFTR was subcloned from pcDNA3.1 into pAcGFP1-C1 (Clontech, #632470) using the following primers: 5’-ctaggtaccatgcagaggtcgcctctggaaaat-3’ and 5’-taaacgggccctaaagccttgtatcttgca-3’. The GFP/mCherry (donor/acceptor) pair was used for acceptor photobleach FRET. Images for GFP and mCherry were collected before and after photobleaching with the 594-nm argon/2 laser at the maximum intensity. From the images, the signal intensity of GFP was measured with Zeiss image software, and FRET efficiency was calculated using the following formula: FRETefficiecy=(Ipost-IpreIpre) , where Ipre and Ipost correspond to the GFP signal intensity (with background signal subtracted) before and after photobleach, respectively. Note that FRET between Δ27-264 and ΔF508 does occur within the ER region.

Three variants of LOV2 were used: wild-type, dark state mutant (C450A, L514K, G528A, L531E, and N538E), and lit state mutant (I510E/I539E) (Supplementary Table 2). 24 (link) The cDNA of full-length rat cofilin was used for all constructs. The Z affibodies that selectively bind dark state LOV2 have been described elsewhere. 24 (link) For transient expression in mammalian cells, constructs were cloned into pmCherry-C1 (Clontech Laboratories, Inc.). Cells were transfected with Lipofectamine 2000 (Life Technologies) using the manufacturer’s protocol 24 h before imaging. For imaging of living cells, cells were co-transfected with mCherry Z-lock cofilin and a membrane-anchored yPet (KRas C-terminus) to visualize the cell edge. 51

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.
