Anti ago2

Manufactured by Merck Group
Sourced in United States, Germany, United Kingdom

Anti-Ago2 is a laboratory reagent that specifically binds to and inhibits the activity of the Argonaute 2 (Ago2) protein. Ago2 is a key component of the RNA-induced silencing complex (RISC), which plays a central role in RNA interference (RNAi) pathways. Anti-Ago2 can be used to study the function of Ago2 and its involvement in gene silencing mechanisms.

RIP-based RNA Immunoprecipitation

Check if the same lab product or an alternative is used in the 5 most similar protocols
According to the instructions of RIP kit (Millipore, Bedford, MA, USA), Daoy and D341 cells were lysed in RIP lysate. The magnetic beads were preincubated with antibody IgG (Millipore) and anti-Ago2 (Millipore) at 37°C for 1 h. The cell lysates were immunoprecipitated by the immunoprecipitation method and overnight at 4°C, then the detection of purified immunoprecipitated RNA by qRT-PCR.

After the A549 and NCI‐H1299 cell confluency reached 80%, the lung cancer cells were collected and lysed in the complete RIP lysis buffer. Cell extracts were subsequently incubated with magnetic beads conjugated with anti‐Argonaute 2 antibody (Anti‐Ago2; Millipore) or negative control normal mouse IgG (Millipore) overnight at 4°C, and were then digested with proteinase K (Invitrogen). The immunoprecipitated RNAs were purified with RNeasy MinElute Cleanup Kit (Qiagen), followed by analysis using RT‐qPCR assay. The assay was performed in triplicate.

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.
