Norgen’s Cells and Tissue DNA Isolation Kits are designed for the rapid preparation of genomic DNA from cultured cells as well as various tissue samples and urine. The purified genomic DNA is fully digestible with all restriction enzymes tested, and is completely compatible with PCR and Southern Blot analysis.
Cells and Tissue DNA Isolation Kit (Spin Column)
Purification is based on spin column chromatography as the separation matrix. Norgen’s columns bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The protocol can be completed in approximately 30 minutes for cells and within 90 minutes for tissues. Each kit contains sufficient materials for 50 preparations.
Cells and Tissue DNA Isolation Micro Kit (Micro)
Optimized for small inputs of cells and tissues, such as Laser-Captured Microdissection (LCM). Purification is based on spin column chromatography as the separation matrix. Norgen’s columns bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. Preparation time for a single sample is approximately 60 minutes, and each kit contains sufficient materials for 50 preparations.
Cells and Tissue DNA Isolation Kit (Magnetic Bead System)
Purification is based on the use of magnetic beads that bind DNA under optimized binding conditions. Norgen’s Cells and Tissue DNA Isolation Kit (Magnetic Bead System) allows for the isolation of genomic DNA from various types of animal tissues or cell samples. Preparation for 10 purifications is approximately 40 minutes of hands-on time.
Cells and Tissue DNA Isolation 96-Well Kit (High Throughput Magnetic Bead System)
Purification is based on the use of magnetic beads that bind DNA under optimized binding conditions. Norgen’s Cells and Tissue DNA Isolation 96-Well Kit (Magnetic Bead System) allows for the isolation of genomic DNA from various types of animal tissues or cell samples. The Cells and Tissue DNA Isolation 96-Well Kit (Magnetic Bead System) also can be integrated with a robotic automation system.

Library size selection is an enrichment of a specific range of library sizes for NGS library preparations. The NGS library preparation is related to the quality of the sequencing data. Precise NGS library size selection can increase sequencing efficiency, improve data quality, and reduce costs.
There are two types of sequencing technologies: short-read sequencing and long-read sequencing. Short-read sequencing uses DNA libraries that contain small insert DNA fragments of similar sizes, usually several hundred base pairs. The sequencing efficiency can be improved if the DNA size selection is in the right range. Cat.# 20104S and 20104L are the best kits for NGS library size selection of illumina paired-end 100 (PE100) sequencing with 100-200 bp library inserts; Cat.# 20105S and 20105L are the best kits for NGS library size selection of illumina paired-end 150 (PE150) sequencing with 150-300 bp library inserts; and Cat.# 20106S and 20106L are the best kits for NGS library size selection of illumina paired-end 300 (PE300) sequencing with 300-600 bp library inserts.
Long-read sequencing uses a large DNA fragment as input and makes very long reads. Usually, library size selection is preferred to remove smaller fragments. Cat.# 20110S and 20110L are the best kits for long-read sequencing size selection with DNA sizes >5 kb, and Cat.# 20111S and 20111L are the best kits for long-read sequencing size selection with DNA sizes >10 kb.
The magnetic beads, or SPRI (Solid Phase Reversible Immobilization) beads, is well used for the purification of DNA due to their reversible DNA binding. The NGS library can be size-selected by the magnetic beads or SPRI beads. The properties of the magnetic beads can be changed for a specific range of DNA binding. The contaminants and other unwanted components in the libraries can also be removed during size selection.
Specific ranges of NGS libraries can be selected using magnetic beads with different buffer compositions. The first DNA-beads binding step, also called the right-side clean-up, removes large NGS library fragments. The large NGS library fragments that bind to the beads are discarded with the beads pellet. The desired NGS library fragments in the supernatant are transferred to a new well, and new beads are added to the supernatant for the second beads-DNA binding, also called the left-side clean-up. After the rinsing step, the NGS library fragments with the dual selection are eluted in water or an appropriate buffer. The magnetic beads method has great advantages over time-consuming column purification and tedious gel-based purification.
.
Library size selection for long-read sequencing only requires a single clean-up. In this case, only the large library fragments are bound to the beads, while other small library fragments are discarded with the supernatant. The selected larger library fragments are eluted in water or an appropriate buffer after the rinsing step.
