Modulating lncRNA4344 in NR8383 AMs

Check if the same lab product or an alternative is used in the 5 most similar protocols
NR8383 AMs were cultured in Ham’s F12K medium supplemented with 15% fetal bovine serum (Excell Bio, Shanghai, China) in a humidified atmosphere with 5% CO2 at 37°C. Then, all of the cells were plated in a six-well plate for further experiments. The small interfering RNA (siRNA) duplexes for lncRNA4344 (NONRATT004344.2, sequence: 5ʹ-GCAGCAGAAGTCACTTATA-3ʹ) were commercially synthesized by RIBOBIO (RIBOBIO Co., Guangzhou, China). We used siRNA-lncRNA4344 and siRNA-scrambled to transfect NR8383 AMs at 70% confluence following Lipofectamine 2000 referencing the product instructions. After transfection for thirty-six hours, NR8383 AMs were exposed to LPS (1µg/ µL) (Sigma Chemical Co., USA) for 6 h. Total RNA was isolated and purified following the manufactory protocol. PCR analysis for lncRNAs and mRNAs was performed. The primer sequences for PCR are shown in Supplementary Table 1. miRNA quantification: Bulge-loopTM miRNA qRT-PCR Primer Sets (one RT primer and a pair of qPCR primers for each set) specific for miR-138-5p and U6 were designed by RiboBio (RiboBio BioTech, Guangzhou, China).

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.
