Magen’s HiPure columns are prepared by high quality glass fiber filter membrane as raw materials through membrane cutting, membrane release, ring release, ring pressing, gland, weighing and other processes. HiPure nucleic acid adsorption columns have the characteristics of long-term stability and high binding capacity. Experiments show that the highest binding capacity and binding efficiency of HiPure nucleic acid adsorption columns are basically unchanged when stored at room temperature for 4 years.
The series of nucleic acid columns produced by Magen Biotech are based on carefully selected imported glass fiber membranes (GF/B, GF/D, GF/F). Columns production processes such as polypropylene injection molding materials, injection molding process, and downstream membrane packing and compression rings are strictly controlled. This is to ensure that the column has extremely high adsorption capacity and long-term stability. Compared with conventional products on the market, Magen’s columns are with varieties, and binding rate will not change when stored at room temperature for 4 years.

Adsorption Mechanism
Based on the negatively charged DNA skeleton, it has a high affinity for positively charged glass fibers. In high salt and ethanol solutions, DNA/RNA binds to glass fiber and interacts with hydrophilic matrix on silica through hydrogen bond. DNA/RNA is tightly bound. All pollutants can be removed by washing solution. At high salt concentration, nucleic acids selectively bind to silica gel membrane, while other pollutants, mainly proteins, are removed by membrane washing.

The Bisulfite Sequencing Library Prep Kit (illumina platform) was developed for construction of NGS libraries using bisulfite treated DNA (50 ng – 500 ng) as input. DNA methylation is an epigenetic mechanism known to play a critical role in gene regulation and genomic imprinting by blocking transcription factor access to promoters and enhancers. Bisulfite sequencing is a popular technique in biomedical research based on C to T conversion under the treatment of sodium bisulfite.
Recently, NGS became a powerful tool to identify the DNA methylation status at the whole genome level with single-base resolution. However, it is well known that bisulfite treatment of the NGS libraries causes tremendous damage to the libraries.
Bisulfite-Seq kit comparison
In the case of the regular bisulfite seq library preparation (library prep before bisulfite conversion), the DNA shearing equipment and the expensive methylated adaptors are required. In addition, the subsequent bisulfite conversion causes tremendous DNA damage to the constructed libraries.
BioDynami has developed a unique library prep technology to solve the problems. The technology uses bisulfite treated DNA as input to avoid the significant library loss caused by bisulfite conversion. Furthermore, DNA shearing step and expensive methylated adaptors are not required with our kit. The DNA polymerase in the kit has high-fidelity amplification ability and uracil tolerance which is ideal for amplification of bisulfite sequencing libraries. The final library is strand specific.
Bisulfite Sequencing Library Prep Kit Workflow
Three index types are available for the kit:
Non-index (Cat.# 30091): Libraries do not have index.
Index (Cat.# 30092): Each primer contains a unique barcode sequence of 6 bases to identify the individual library. Library multiplexing capacity is up to 48 samples. Index information can be downloaded here.
Unique dual index (Cat.# 30093): The multiplexing of bisulfite sequencing library is up to 96 samples with unique dual indexes. We used a Four-Base Difference Index System to generate indexes that have at least 4 bases different from each other in the 8-base index. The index primers remove NGS errors including index cross-contamination, index hopping, reads mis-assignment etc. Index information can be downloaded here.
