Detail
The Permagen 384-well post magnet plate was designed for use in manual or automation applications for Low Elution high throughput PCR
Magnetic beads are pulled midway up onto well wall to help eliminate accidental bead pellet disruption and to achieve lower volumes
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, compatible with any magnetic beads, and integrated cushion base to help aid in robot/ consumable inconsistencies
Double-Strand Specific dsDNase (dsDNase) is ideal for fast and effective removal of contaminating DNA from PCR master mixes.
Taq polymerases are commonly contaminated by bacterial DNA. This is a problem in PCR based bacterial typing and detection as it might cause false positive results. The unique properties of dsDNase make it suited for removal of contaminating DNA from PCR master mixes prior to addition of DNA template.
In figure 1, a PCR master mix was treated with different amounts of dsDNase before performing a qPCR to measure the contaminating bacterial DNA in the master mix. ArcticZymes dsDNase effectively removed contaminating DNA below known levels of the assay detection limits.
The dsDNase from Arctic shrimp (Pandalus borealis) is recombinantly produced in Pichia pastoris. It cleaves phosphodiester linkages in DNA to yield oligonucleotides with 5’-phosphate and 3’-hydroxyl termini.
The specific activity is estimated to be 30 times higher than that of bovine DNase I. In the presence of magnesium as only divalent cation and using oligos as a substrate, the activity towards dsDNA is 5000-fold higher than towards ssDNA.
The unique double strand-specificity allows specific degradation of dsDNA while leaving shorter ssDNA as primers and probes essentially intact. Easy inactivation by moderate heat (65°C) allows addition of DNA intended for analysis directly after removal of contaminating DNA.
Can be heat-inactivated by moderate heat treatment (65°C for 15 minutes)
Producing 5′-phospho-oligonucleotide products

The dsDNase effectively removes contaminated DNA:
A PCR master mix was preincubated with various concentrations of dsDNase. After treatment, no DNA was amplified in non-template controls.
Properties
Specificity towards double-stranded DNA
Nucleic acid specificity has been tested towards double- and single-stranded DNA and RNA oligonucleotides. The specificity of dsDNase towards the substrate has been measured using 15-mer oligonucleotides with FAM at 5′ and DarkQuencher® 3′ (Eurogentec). The fluorescence is proportional to enzyme activity. Assay conditions: 25 mM Tris pH 7.5, 5 mM MgCl2, and 2 μM oligonucleotide.

Product Info
The ChIP-Seq Library Prep Kit (illumina and MGI Platform) was developed for the construction of high quality ChIP-Seq libraries using 5 ng to 400 ng of ChIP DNA as input. The kit is compatible with ChIP DNA fragments generated from both enzymatic methods and physical methods (sonication, nebulization etc.).
ChIP-Seq Library Prep Kit Workflow
ChIP-Seq is the combination of chromatin immunoprecipitation (ChIP) with next generation sequencing. It is a powerful tool for the analysis of global transcription factors and other proteins in diseases and biological pathways, and characterization of histone modifications in a genome-wide level at single-base resolution. ChIP-Seq delivers whole genome level of functional profiling of global transcription factors, and provides better understanding of epigenetic modifications.
Three index types are available for the ChIP-Seq Library Prep Kit of the illumina platform:
Non-index (Cat.# 30032): Libraries do not have index.
Index (Cat.# 30034): Each index primer contains a unique 6-base index sequence can be used for identification. 48 samples can be pooled together. Index information can be downloaded here.
Unique dual index (Cat.# 30036): The ChIP-Seq library multiplexing for 96 samples is possible. Our unique 4-Base Difference Index System have 8 bases index length and at least 4 bases are different from each other for better library identification. Our unique dual indexing primers remove sequencing errors such as index hopping, index contamination, mis-assignment, and other errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34034).
Kit advantages:
Super fast protocol
Library prep can be done in 1.5 hours
The hands-on time is only around 10 minutes
Easy procedure
Ready-to-use master mix simplified the procedure
Less reaction components make it easy to setup reactions
Reduced more than half of the beads cost

Solid Phase Reversible Immobilization (SPRI) beads are a simple and effective reagent for DNA purification, but not for short oligo purification. The beads are paramagnetic particles coated with carboxyl groups that can reversibly bind to nucleic acid. However, SPRI beads can only purify DNA/RNA fragments that are 100 base pairs or longer. DNA/RNA fragments shorter than 100 base pairs are not effectively recovered.
Oligo purification can also be performed using spin column-based technology. The oligo size limitation for recovery is around 20 nt, as oligos under 20 nt have a very low recovery rate.
We have developed Magnetic Beads (Short Oligo Purification) Kit for short oligo purification. Our proprietary bead technology enables the recovery of oligos as short as 6 nt. 80% of the 6 nt oligos and 90% of the > 8 nt oligos can be recovered. The reagent also effectively removes impurities and unwanted components such as salts, proteins, dNTPs, detergents, and other contaminants. The magnetic bead reagents are RNase free, and can be used for both DNA and RNA applications.
Recovery rates of of short oligos. Oligos with different sizes were used as input. BioDynami Short Oligo Quantification Kit (Cat. # 40046) was used to quantify the recovery rates with modifications.
