Lipofectamine lipo 2000

Manufactured by Thermo Fisher Scientific
Sourced in China, United States

Lipofectamine (Lipo) 2000 is a cationic lipid-based transfection reagent used for the delivery of nucleic acids, such as DNA and RNA, into eukaryotic cells. It facilitates the uptake of these molecules by forming complexes with the genetic material, which can then be internalized by the target cells.

CXCL10 Promoter Mutagenesis and Luciferase Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
A series of CXCL10 promoter constructs were prepared with the primers shown in the supporting information Table S3 following the previous reports [7 (link)]. Point mutations in two NF-κB sites, NF-κB1 and NF-κB2, were generated in the −267/+97 construct as indicated before [7 (link)]. The DNA sequencing results showed that all the plasmids were constructed successfully.
HUVECs were plated in a 48-well plate. When the confluence was 70%, cells were transfected with 0.4 μg of each CXCL10 promoter reporter constructs and 5 ng of the pRL-TK plasmids using Lipofectamine (lipo) 2000 (Invitrogen, USA) as manufacturer's protocol. Forty-eight hours later, luciferase activity in each sample was detected with the Dual-luciferase reporter assay system (Promega, USA) according to the manufacturer's instructions and the transfection efficiency was normalized by Renilla luciferase activity. For data analyses, pGL3-basic vector control was set as 1.

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.
