Detail
Permagen’s 5 mL Centrifuge Tube Magnetic rack is designed for magnetic bead separations from up to eight, 5 mL Centrifuge tubes
Accommodates any common 5 mL Centrifuge Tubes
Rapid bead separations
Beads will be pulled to back wall allowing easy aspiration and tip tracking down the front wall of the tubes without disturbing bead pellet
Features include solid aluminum alloy design with hard coat finish for years of trouble-free use, rubber feet to help prevent slipping on work bench, less tippy than common plastic products, and fast separations using any magnetic beads
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.

Usages： Determination of coliform and fecal coliform for multiple tube fermentation.
Principle: Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
How to use: 1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby . 2.Sample handling and dilution. 3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL. 4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h. 5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if gas production then will have to make further confirmed by experiments.
Quality control: Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows: Bacterial Name Bacterial No. Growth Status Gassing Escherichia coli ATCC25922 good +
Salmonella typhimurium CMCC (B) 50115 good —
Staphylococcus aureus ATCC6538 inhibited —
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
