What are the nucleic acid purification technologies?

At present, nucleic acid purification technologies widely used in scientific research can be divided into two categories: those that use media and those that do not use media. If media is used, nucleic acid is separated from all other impurities at one time; if media is not used, the first step is to separate the […]

Application of immunomagnetic beads in the field of biomedicine

Immunomagnetic bead technology is a technical method that appeared in the 1980s.
