Plvx ef1alpha ires mcherry vector

Manufactured by Takara Bio
Sourced in United States

The PLVX-EF1alpha-IRES-mCherry Vector is a lentiviral expression vector that allows for the simultaneous expression of a gene of interest and the mCherry fluorescent reporter protein. The vector utilizes the EF1alpha promoter to drive gene expression and the IRES sequence to facilitate bicistronic mRNA translation.

Multicolor Assay for Selective Advantage

Check if the same lab product or an alternative is used in the 5 most similar protocols
Selective advantage was performed through multicolor competition assay as previously described (Smogorzewska et al., 2007 (link); Zhang et al., 2016 (link)). Fibroblasts were transduced with a RAD50-IRES–mCherry expressing lentivirus vector (pLVX-EF1alpha-IRES-mCherry Vector, Takara Bio) or mCherry-expressing vector and treated or not with 100 ng/ml phleomycin for up to 18 days. The number of mCherry-positive cells was scored at various time points to assess for relative selective advantage of transduced (mCherry+) over untransduced (mCherry-) cells.

For complementation of phleomycin sensitivity, patients’ SV40-transformed fibroblasts were transduced with a wtRAD50-IRES–mCherry expressing lentivirus vector (pLVX-EF1alpha-IRES-mCherry Vector, Takara Bio) or empty mCherry-expressing vector. Cells were cell sorted thanks to mCherry expression to obtain 100% of transduced cells. Sensitivity assays were then conducted as described above.

Lentiviral-mediated IKBKB Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
For reconstruction of WT or the mutant IKBKB expression to the IKBKB knocked out Jurkat E6–1 clone, the WT or mutant IKBKB cDNA was cloned into the pLVX-EF1alpha-IRES-mcherry Vector (TAKARA Bio USA, CA, USA). Lenti-X 293 T cells (TAKARA Bio USA) were plated into a T75 flask at a density of 9.4 × 106 cells overnight. The cells were transfected using Lipofectamine 3000 (Invitrogen) following the manufacture’s protocol with 10 μg of the pLVX-EF-1alpha IKBKB-IRES-mcherry vector or 10 μg of the pLVX-EF-1alpha IRES-mcherry vector, and two helper plasmids as 10 μg of psPAX2 plasmid (Addgene) and 1 μg of pMD2.G plasmids(Addgene). At 48 h after transfection, viruses were collected from the supernatants and concentrated by 100-fold using Leni-X Concentrator (TAKARA Bio USA). The IKBKB knocked out Jurkat E6–1 clones were infected with 10 μl of the concentrated viruses in RPMI containing 10% fetal bovine serum and 10 μg/ml of polybrene by spinning down the cells at 32 °C for 90 min.

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.
