Customer Reviews
I have been purchasing this product from them for a long time, and the cooperation has not had any major problems so far. This is a reliable supplier that I highly recommend.The RNA extraction kits is as good as Qiagen.

—— Bundit K

Their sales team is very professional, the goods arrive on time, a very reliable manufacturer. The swabs and kits are selling well in our market.

—— David Mupenzi

nice team, the Sars-Cov-2 Detection kits is nice to us eon Covid-19 test, easy use, and high sensitivity.

—— Eliseo Herrera

great product,will always work with them. great to be used on detecting for Covid-19 pcr test great team help us to win the tender for Covid-19 detecting

—— Genevieve Thompson

Received in good condition. Highly satisfied! The PCR mix is packing well in ice packs,i recommend FOREGENE

—— Alberto Licata

The product was perfectly packed and stored during the delivery, and when used it delivered the expected test results.

—— James Watts

Really I appreciate the quick response of the supplier to my problem , solved the problem efficiently. I am recommending FOREGENE if you need anything related to nucleic acid purification very professional company

—— Nikolay Sviridov

a highly recommended. very helpful. extremely fast shipping. I am sure the quality will be as good as the seller is We buy SF PCR machine,very good.

RNA pull-down

RNA pull-down



RNA molecules can interact extensively with other biological molecules, such as protein, DNA and RNA, and thus exist in cells and organisms in the form of macromolecular complexes. Among them, RNA-protein complexes are the existence and function of RNA One of the important forms of. RNA pull-down is a classic method for screening and identifying RNA molecules, especially the interacting proteins of lncRNA molecules, and is recognized by the majority of researchers and international authoritative academic journals. Today FORREGENE will share with you the experimental principle and technical process of RNA pull-down, maybe you can use it

1. The experimental principle of RNA pull down technology:

In vitro transcription and synthesis of biotin-labeled target lncRNA or lncRNA fragments (including RNA fragments used as positive and negative controls), and incubate with cell extracts; use avidin-anchored magnetic beads to collect RNA-protein or RNA-RNA complexes, After thorough washing, the complex is eluted. If detecting the protein target molecule that interacts with lncRNA, perform protein electrophoresis on the RNA-pull down product, detect the target protein by silver staining, and cut the gel for mass spectrometry; also directly perform western blot verification on the pull-down product; if detected For RNA target molecules that interact with lncRNA, RNA-pull down products are subjected to RNA extraction and specific qRT-PCR detection is performed.
