N-(t-Boc-Aminooxy-PEG2)-N-bis(PEG3-propargyl) is a branched crosslinker molecule with two terminal propargyl groups and a t-Boc protected aminooxy group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
Simultaneous concentration, desalting and buffer exchange of total urinary proteins
No molecular weight cutoff allows for isolation of all sizes of proteins and peptides
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
These kits concentrate urine proteins while simultaneously removing salts, urea, and other urine contaminants. There is no molecular weight cut-off and therefore the columns capture total urinary proteins and peptides of all sizes making them ideal for biomarker discovery work, differential expression of proteins in various diseases, or other diagnostic research. The columns are convenient, rapid and easy to use and thus offer significant time savings over classic dialysis protocols. The resulting high-quality protein sample is concentrated and free from the original sample salts, thus preparing the sample conveniently for downstream proteomic applications including SDS-PAGE, 2D Gels, MALDI-TOF, LC/MS, LC/MS/MS, whole protein mass spectrometry, western blotting, protein microarrays, and more.
ProteoSpin™ Urine Protein Concentration Micro Kit
Each spin column is able to concentrate and desalt up to 200 μg of urine proteins. Twelve samples can be processed in 20 minutes.
ProteoSpin™ Urine Protein Concentration Midi Kit
The ProteoSpin™ Urine Protein Concentration Midi Kit provides a fast and simple procedure for concentrating dilute solutions of urine proteins from 1 to 5 mL inputs of urine. Each mini spin column is able to concentrate and desalt up to 3 mg of urine proteins in 30 minutes.
ProteoSpin™ Urine Protein Concentration Maxi Kit
The ProteoSpin™ Urine Protein Concentration Maxi Kit provides a fast and simple procedure for concentrating dilute solutions of urine proteins from 2 to 20 mL inputs of urine. Each maxi spin column is able to concentrate and desalt up to 4 mg of urine proteins in 45 minutes.
Storage Conditions All solutions should be kept tightly sealed and stored at room temperature. Once opened, the solution should be stored at 4°C. This kit is stable for 2 years after the date of shipment.

NGS DNA Fragmentation & Library Prep Kit (illumina and MGI Platforms)

Product Info
The NGS DNA Fragmentation & Library Prep Kit (illumina and MGI Platforms) was developed for construction of high quality libraries for next generation sequencing. The kit uses intact genomic DNA (EDTA-free DNA or DNA resuspended in TE buffer) as input DNA without an additional DNA fragmentation step. Our technology provides a fast and simple workflow. DNA libraries can be generated around 2 hours with only 10 min hands-on time. Library multiplexing is possible.
NGS DNA Fragmentation & Library Prep Kit Workflow
The incorporation of DNA fragmentation in the kit makes it possible to directly use intact genomic DNA as input DNA without the need of mechanical DNA shearing or enzymatic DNA fragmentation. The NGS DNA Fragmentation & Library Prep Kit does not generate sequencing bias as compared to library using mechanical sheared DNA as input. Sequence coverage is also consistent between enzymatic shearing and mechanical shearing. The library size is inversely correlated with the incubation time of step 1 at 20°C.
Three index types are available for the kit of the illumina platform:
Non-index (Cat.# 30026): Libraries do not have index.
Index (Cat.# 30028): Each of the index primers contains a unique index sequence of 6 bases. Library multiplexing for 48 samples is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30030): Library multiplexing for 96 samples is possible. With the unique features of our 4-Base Difference Index System, the index sequence is 8-base long and each index has 4 bases different from others. Our unique dual index primers effectively identify sequencing errors such as index hopping, mis-assignment of reads, and de-multiplexing errors etc. The unique dual index primers set consists of 96 pre-mixed unique pairs of index primers. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34028).
Kit features:
1.5-hour protocol from intact genomic DNA to NGS library
Intact genomic DNA as input, DNA fragmentation is not needed.
Works with both EDTA-free DNA and DNA resuspended in TE buffer
Library conversion efficiency: 100 ng, 300 ng and 500 ng of intact genomic DNA were used as input.
The library size is inversely correlated with the incubation time of step 1 at 20°C.
NGS data comparison: enzymatic shearing versus mechanical shearing
Enzymatic shearing • DNA shearing and library prep: BioDynami NGS DNA Fragmentation & Library Prep Kit Mechanical shearing • DNA shearing: Covaris sonication • Library prep: BioDynami NGS DNA Library Prep Kit.
