Sanprep column mirna extraction kit

Manufactured by Sangon

The SanPrep column miRNA extraction kit is a tool designed to isolate and purify microRNA (miRNA) from various biological samples. It utilizes a silica-based column chromatography technique to selectively capture and concentrate miRNA molecules. The kit provides a straightforward protocol for efficient miRNA extraction, enabling researchers to obtain high-quality miRNA samples for downstream analysis and applications.

RNA was extracted using an RNAeasy™ Animal RNA isolation kit with a spin column (Beyotime, #R0026), and miRNA was extracted using a SanPrep column miRNA extraction kit (Sangon Biotech, #B518811), according to the manufacturer’s instructions. RNA reverse transcription, cDNA verification, preparation of a real-time PCR system, and determination of the reaction conditions were carried out as described previously. β-actin and U6 were the reference genes. The primers are listed in Table 3.

Total RNA from cells and tissues were extracted using Trizol reagent (Invitrogen, USA) following the manufacturer’s instructions. For lncRNAs and mRNAs, Transcriptor First Strand cDNA synthesis Kit (Roche, 0489703000) was applied for reverse transcriptions. qRT-PCR was performed using FastStart Universal SYBR Green Master (Rox) (Roche, 4913850001) on the instrument of ABI 7500 (Thermo, USA). For miRNAs, SanPrep Column miRNA Extraction Kit(Sangon Biotech, B518811), miRNA First Strand cDNA Synthesis (Sangon Biotech, B532453) and miRNA qPCR Kit (Sangon Biotech, B532461) were adopted. Relative gene expressions were determined using the 2–ΔΔCT method. The primers were described in Table 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.
