The Biospin Whole Blood Total RNA Purification Kit is designed for extracting and purifying high-quality RNA from both frozen and fresh whole blood samples. This kit utilizes a specially formulated lysis buffer to release RNA from the blood samples. The RNA is then selectively bound to the purification column with the action of ethanol. Through two washing steps, impurities are removed, and finally, RNA is eluted and collected from the purification column with the elution buffer. The purified RNA product from this kit can be directly used in downstream experiments such as Northern Blot, RT-PCR/Real Time, RT-PCR, in vitro translation, etc.
