Is the NadPrep rRNA Fast Blocking Comprehensive Solution suitable for severely degraded FFPE samples?

Title: Is the NadPrep rRNA Fast Blocking Comprehensive Solution suitable for severely degraded FFPE samples? A: This solution is suitable for RNA samples from a wide range of cell and tissue sources with varying degradation levels. However, it is not recommended for severely degraded FFPE samples (DV 200 < 20%).

Is the NadPrep rRNA Fast Blocking Comprehensive Solution compatible with other third-party RNA library preparation kits?

Title: Is the NadPrep rRNA Fast Blocking Comprehensive Solution compatible with other third-party RNA library preparation kits? A: Yes, it is. This solution can be integrated with RNA library preparation kits for the preparation of total RNA sequencing (RNA-Seq) libraries. If you choose a third-party RNA library preparation kit, we recommend using NEBNext® Ultra™ II RNA Library Prep Kit for Illumina® (NEB, Cat # E7770L) or the KAPA RNA HyperPrep Kit (Roche, Cat # KK8541). For the use of RNA library preparation kits from other brands, please consult technical support from Nanodigmbio with support@njnad. com.

Why is the dsDNA yield slightly higher when prepared using the NadPrep rRNA Fast Blocking Comprehensive Solution?

Title: Why is the dsDNA yield slightly higher when prepared using the NadPrep rRNA Fast Blocking Comprehensive Solution? A: This solution contains a large amount of rRNA ssDNA blocking reagent. When used in conjunction with the NadPrep Total RNA-To-DNA Module, there may be a slight residual of ssDNA in the purified dsDNA product. When quantifying dsDNA using a nucleic acid fluorescence quantifier, this residual ssDNA can influence the results, leading to a slightly higher yield. However, the remaining rRNA ssDNA blocking reagent does not affect subsequent experiments. We recommend appropriate adapter dilution factors and PCR amplification cycles for different different types of RNA and different input amounts
