A guide to large-scale RNA sample preparation
The required sample preparation on a large scale often constitutes the limiting step, as each structural method strongly relies on the quality (and often quantity) of the RNA sample that has to be provided (Fig. 1 ). Hence first we will give a

- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density. Because of its low cost, high efficiency, and simple operation, CPAM is widely used as a chemical conditioner for flocculation pretreatment of sludge before mechanical dewatering (Sun et al. 2018; Zhou et al. 2014 ).
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- Is CPAM a cationic microblock?
- It has been shown that the flocculation performance of CPAM is related to the distribution and sequencing of cationic units in the molecular chain (Feng et al. 2018b). The continuous arrangement of cationic units in CPAM can form cationic microblock structure.
