Performance

Compatible with Different Input Amounts for Various Sample Types

Figure 1. Performance of the NadPrep rRNA Fast Blocking Comprehensive Solution for different sample types and input amounts. A. rRNA ratio; B. No. of genes detected; C. Transcript coverage. Libraries were performed using the NadPrep rRNA Rapid Blocking Comprehensive Solution connected to the NadPrep DNA Universal Library Preparation Kit. Sequencing platform: Illumina Novaseq 6000, PE150. 0.3 Gb of data per sample was randomly selected for data analysis.
Note: The Cell line is Human Brain Total RNA(Takara, 636530); DV 200 values for FFPE A and FFPE B are 69% and 32%, respectively.

Compatible with FFPE Samples of Different Quality Grades

Note: For samples derived from FFPE with an input of 250 ng, the DV 200 values are 72%, 69%, 61%, 57%, 48%, and 32%, respectively.

Compatible with Third-party RNA Library Preparation Kits

Figure 3. Performance of the NadPrep rRNA Fast Blocking Comprehensive Solution when combined with a third-party RNA library preparation kit. A. rRNA ratio; B. No. of genes detected; C. Transcript coverage; D. Expression profile correlation. 250 ng of K562 cell line RNA was used with the NadPrep rRNA Blocking Reagent in conjunction with the NadPrep Total RNA-To-DNA Module coupled with the NadPrep DNA Universal Library Preparation Kit, the KAPA RNA HyperPrep Kit, and the NEBNext® Ultra II RNA Library Prep Kit for Illumina® to complete the library preparation.

Compatible with MGI and Illumina Sequencing Platform

Figure 4. Performance of the NadPrep rRNA Fast Blocking Comprehensive Solution on dual sequencing platforms. A. rRNA ratio; B. No. of genes detected. With an input of 250 ng, libraries were prepared using the NadPrep rRNA Fast Blocking Comprehensive Solution in combination with the NadPrep DNA Universal Library Preparation Kit, coupled with the NadPrep Universal Stubby Adapter (UDI) Module and NadPrep Universal Adapter (MDI) Module respectively. Sequencing platform: DNBSEQ-T7 and Illumina Novaseq 6000, PE150.

Competitive Comparison

Figure 5. Performance comparison between the NadPrep rRNA Fast Blocking Comprehensive Solution and competitors. A. rRNA ratio; B. No. of genes detected; C. Transcript coverage; D. Expression profile correlation. 250 ng of input, libraries were prepared using NadPrep rRNA Blocking Reagent, Vendor A, and Vendor B in combination with the NadPrep Total RNA-To-DNA Module.

Note: Vendor A refers to the rapid removal method, and Vendor B refers to the RNase H enzymatic method. C&D are shown only with the cell line (K562 RNA).

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?

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?

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
