Thereafter, subsamples of approximately 2 g feces were collected from each animal in all groups and pooled in separate plastic containers. After blending the pooled fresh feces with Vermiculite, the eggs were cultured for approximately 10 days in a moistened chamber at ≈20 °C [24 (link)]. Infective third-stage larvae (L3) were harvested using the Petri dish method, concentrated in a Falcon tube and collected into an Eppendorf tube before storage in a freezer at approximately − 18 °C [14 (link)]. DNA was then extracted from the larval cultures (one per group and sampling occasion) using the Nucleospin® DNA tissue kit (Macherey-Nagel, Düren, Germany) following the manufacturer's guidelines.
Nucleospin tissue dna kit
The Nucleospin Tissue DNA Kit is a DNA extraction kit designed for the isolation of genomic DNA from various biological samples, such as animal tissues, cultured cells, and bacteria. The kit utilizes a silica-membrane-based technology to efficiently bind, wash, and elute high-quality DNA.

Tissue DNA Extraction Protocol
Quantitative Telomere Length Analysis
Relative Human Telomere Length Quantification qPCR assay (ScienCell) was used to determine relative telomere length. Two separate PCR reactions were performed in triplicate for each sample using telomere or SCR primer sets and PowerTrackTM SYBR Green Master Mix. An equivalent of 4 ng genomic DNA per reaction was used, in a total of 20 μl per well. Amplification was performed under the following conditions: denaturation for 10 min at 95°C, followed by 32 cycles of denaturation for 20 s at 95°C, annealing for 20 s at 52°C and extension for 45 s at 72°C. The relative telomere length was calculated according to the instructions in the manufacturer’s protocol.

DNA was extracted from 50 μl mouse serum using the QIAamp MinElute Virus Spin Kit (Qiagen, Hilden, Germany) or 20 mg of liver tissue using a NucleoSpin Tissue DNA Kit (Macherey-Nagel, Dueren, Germany) according to the manufacturer’s instructions. The quantification of HBV-DNA was performed through real-time PCR with SYBR green as previously described.22
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
