Pgfp c shlenti plasmid

Manufactured by OriGene
Sourced in United States

The PGFP-C-shLenti plasmid is a laboratory tool designed for gene knockdown experiments. It contains a green fluorescent protein (GFP) reporter and a short hairpin RNA (shRNA) expression cassette. This plasmid can be used to generate lentiviral particles for the delivery and expression of shRNA in target cells, enabling researchers to study the effects of gene silencing.

Immortalized Fibroblast Generation

The pBABE-neo-hTERT plasmid (#1774, Addgene) was used to generate immortalized fibroblasts. NF47 and CAF47 cells were infected with retroviruses and passaged. hTERT levels were validated using RT-PCR. The pGFP-C-shLenti plasmid containing anti-TINAGL1 (TL307228, Origene) or scrambled negative control sequences (TR30023, OriGene) were used to generate stable cell lines. Immortalized CAFs were infected with lentivirus, and GFP-expressing cells were selected. TINAGL1 levels were validated by RT-PCR.

Efficient Gene Knockdown Techniques

For stable knockdown (shRNA) of IDO1, ALC cells were transfected with 1μg of pGFP-C-shLenti plasmid (Origene) expressing shIDO1 (NM_002164) or scrambled control using lipofectamine 2000 (Thermo Fisher) transfection reagent (see Supplemental Method). After 24h, transfection medium Opti-MEM was exchanged to RPMI1640 containing 5μg/ml of G418. GFP as a reporter was used to evaluate target gene knocked down efficiency. For siRNA, cell lines A were transfected with 1nM of HIF1α SMARTpool® siRNA (NM_005566) or siCONTROL®(Dharmacon) using INTERFERin™ transfection reagent (Polyplus) as previously described (26 (link)).

Lentiviral-mediated SLC2A1 knockdown

Check if the same lab product or an alternative is used in the 5 most similar protocols
HCT-116 cells were infected with lentivirus containing either SLC2A1-specific short hairpin RNA or scrambled short hairpin RNA in pGFP-C-shLenti plasmid (OriGene). Infected cells were then plated into 96-well microdilution plates to measure cell viability over 6 days by MTT assay as previously described.

Tumor Induction and Visualization on Chick CAM

Check if the same lab product or an alternative is used in the 5 most similar protocols
ISK, and HEC1A cells were labelled with an EGFP-expressing lentivirus donated by Dr Sokratis Theocharatos (University of Liverpool, UK). RL95-2 cells were labelled with a lentivirus expressing tGFP (pGFP-C-shLenti plasmid) (Origene, MD, USA), and selected using puromycin antibiotic selection. ISK and HEC1A viral transfection and egg preparation were performed according to Carter et al. 2012 [20] . Cells were added to the CAM at embryonic day 7 (E7) [21] the resulting tumours were imaged at E14, using a standard Leica M165-FC fluorescent microscope, in situ and after excision.
(Fig. 5C) the resulting tumours were fixed in 10% (v/v) NBF and embedded in paraffin wax.

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.
