Attogene’s 0.5mL Micro Spin Desalting Columns are convenient, simple, and ready to be used out of the box. We provide a product that facilitates equal, if not superior results to leading brands products at a significantly better cost. Superlative recovery of proteins and other macromolecules (>7000 MW) with greater than 95% retention of salts, and other small molecules (<1000 MW), are possible even with very dilute (25 ug/mL) samples. Our columns, which are constructed with a simple break away tab at the bottom, are comprised of polypropylene and contain our own proprietary resin slurry that we’ve developed in house to achieve optimal results. Sample volumes between 30-130uL can be loaded while still achieving expected purification numbers.

NGS DNA Library Prep Kit (illumina and MGI Platforms)

Product Info
The kit was developed for construction of high quality libraries for next generation sequencing (illumina and MGI Platforms). The kit needs double strand DNA fragments (blunt and/or sticky) as input DNA for NGS library preparation, and is compatible with DNA fragments generated from both enzymatic methods and physical methods (sonication, nebulization etc.). Library multiplexing is possible with different types of indexes.
The kit was optimized for next generation sequencing (NGS) library preparation with different types of samples. Most of DNA library preparation requires the ligation of sheared DNA fragments to library adaptors and the DNA library preparation is closely related to the quality of NGS data. With BioDynami’s unique DNA library preparation technologies, the fast and simple kit allows high quality NGS library preparation to be completed in 1.5 hours with only 10 minutes of hands-on time.
Some genomic regions are very difficult to be covered evenly and usually result in very low coverage rate or gap in these regions.
Typical difficult regions are: • with high GC contents • have secondary structures: mainly due to repeat sequences • the worst cases: have both high GC contents and repeated sequences.
Example: human TERT gene is one of the most difficult regions as shown above. NGS data showed that BioDynami kit has the best performance to cover the extremely difficult human TERT gene region.
Three index types are available for the illumina platform kits:
Non-index (illumina Cat.# 30009): Libraries do not have index.
Index (illumina Cat.# 30021): A unique barcode sequence with 6 bases has been included in each of the index primers. RNA Sequencing library multiplexing is possible with up to 48 samples. Index information can be downloaded here.
Unique dual index (illumina Cat.# 30023): RNA Sequencing library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a 4-Base Difference Index System. The system can generate indexes with at least 4 bases different from others in the 8-base indexing region. the unique dual indexing primers identify sequencing errors such as index hopping, mis-assignment, and de-multiplexing errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34021).

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.
