Different types of samples and inputs

Figure 1. Capture performance of μCaler MRD Solution on cfDNA and gDNA libraries with different inputs. A. Mappability and On-target rate; B. Target covered; C. Fold 80 base penalty.Hybrid capture was accomplished using μCaler MRD Solution (for Illumina®) and M71 (8.5 Kb, GC range 25-70%) for Healthy Human-derived Pooled cfDNA Standards and Human Male Genomic DNA (Promega, G1471), and sequenced on Illumina Novaseq 6000 with PE150. The BWA was used for alignment of raw reads to the reference genome (hg38) and On-target rate was calculated by the number of reads.

Figure 2. Capture performance of μCaler^®MRD Solution for different types of panels. A. Mappability and On-target rate; B. Target covered; C. Fold 80 base penalty.Hybrid capture was accomplished using μCaler MRD Solution (for Illumina®) for Human Male Genomic DNA (Promega, G1471) as well as M27 (3.2 Kb, GC range 25-55%), M44 (5.28 Kb, GC range 25-70%), M50 (5 Kb, GC range 37-90%), and M580 (58 Kb, GC range 19-99%).

Analysis of Variation Consistency in Standards

Samples were derived from Pancancer Light 800 gDNA Reference Standard (Genewell, GW-OGTM800) mixed with Human Male Genomic DNA (Promega, G1471) at the ratios of 10:0 and 1:9, respectively, to artificially mimic different mutation frequencies. Theoretical mutation frequencies at different mutation sites for the Pancancer Light 800 gDNA Reference Standard are as follows:

Figure 3. Consistency between expected allele frequency and observed allele frequency in the capture data of μCaler Panel and Traditional Panel. 30 ng simulated samples were used μCaler MRD Solution (for Illumina®) coupled with μCaler Panel and NadPrep Hybrid Capture System coupled with Traditional Panel to complete hybrid capture respectively, and sequenced on Illumina Novaseq 6000 with PE150. The detection consistency of mutations (pre-library containing UMI) was analyzed by sequencing depth from DownSampling each sample data to 80,000x before removing duplication, and the analytical filtering criteria are single-strand consensus sequences (family size ≥ 3) (SSCS ≥ 3).

Customized SNP Panels to Simulate Low Frequency Mutation Limit Detection

gDNA from two healthy donors with known mutation was mixed at ratios of 99:1, 999:1, and 9999:1 to artificially mimic samples with different mutation frequencies. Category 1 contain 19 homozygous mutation with mutation frequency of 1%, 0.1% and 0.01% respectively, and category 2 contain 11 heterozygous mutation with mutation frequency of 0.5%, 0.05% and 0.005% respectively.

Figure 4. Detection of low-frequency mutations by μCaler Panel and Traditional Panel. 50 ng simulated samples were used by μCaler MRD Solution (for Illumina®) coupled with μCaler Panel (about 3 Kb target region, covering 30 allelic loci) and NadPrep Hybrid Capture System coupled with Traditional Panel (about 42 Kb target region, covering 160 allelic loci, including the above 30 loci) respectively, and sequenced on Illumina Novaseq 6000 with PE150. Each pair of samples was subjected to the same depth (pre-library containing UMI) for three downsampling, and the detection of the mutation site was analyzed by Duplex Consensus Sequences (DCS211) as well as SSCS ≥ 3. Average valid reads supporting mutations ≥ 1 are judged as positive.

Note：Theoretical number of mutation is 2,750x of DCS211 depth; the distribution rule of mutation detection by 10,000 random sampling for different mutation frequencies.

Can RNA samples be directly used for library preparation with this kit?

No. This kit is compatible only with gDNA or cDNA as initial samples. For RNA samples, reverse transcription to generate cDNA is required prior to library preparation.

What is the recommended input range? How to handle inputs exceeding this range?

This kit supports 50-2,000 ng of gDNA or cDNA. For input amount exceeds 2,000 ng, split the sample into multiple reactions to maintain amplification efficiency.

What is the insert size of this kit? How to select sequencing read length?

The main peak of PCR products by using this kit is ~270 bp. PE150 sequencing is recommended for high-quality coverage.

What is the recommended sequencing data volume for IGTR immune repertoire analysis?

A minimum of 0.3 Gb is recommended to detect clones at 0.01% abundance with an input of 200 ng. Increase data volume to enhance sensitivity for low-frequency clones.

Is this kit suitable for minimal residual disease (MRD) monitoring?

Yes. This kit includes IG Primer Mix and TR Primer Mix with gene-specific primers provided in separate tubes, allowing flexible combination in a single amplification reaction. With its high sensitivity, the kit meets the requirements for MRD monitoring technology development and clinical applications, making it ideal for low-frequency variant detection scenarios.
