Modulating circRNA and IGF2BP3 Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
RiboBio (Guangzhou, China) synthesized recombinant lentivirus containing short hairpin RNA targeting circ_0053943 (sh-circ_0053943#1/2/3) and IGF2BP3 (sh-IGF2BP3#1/2), along with the full-length targeting sequence of circ_0053943 and IGF2BP3, including the corresponding negative control. Obio (Shanghai, China) synthesized the IGF2BP3 full-length (FL) and truncation-mutation plasmids with a C-terminus 3× Flag tag. Small interfering RNA (siRNA) oligonucleotides targeting methyltransferase-like 3 (METTL3) and methyltransferase-like 14 (METTL14) were also synthesized by RiboBio. Transfection of short hairpin (shRNAs) and plasmid vectors was carried out using Lipofectamine 3000 (Invitrogen). The transfection efficiency was subsequently confirmed through qRT-PCR. Detailed sequences of shRNAs and siRNAs (for silencing) can be found in Suppl. Table 3.

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.
