N-(t-butyl ester-PEG2)-N-bis(PEG2-propargyl) is a multi-functional PEG linker with two terminal propargyl groups and a t-butyl ester. The propargyl groups enables formation of triazole linkage with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry. The t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Champion™ Competent Cells are chemically competent cells, which were prepared by SMOBIO to make E. coli perform excellent transformation efficiency. Standard transformation protocol is recommended for large plasmids or non-ampicillin selection. Time-saving transformation protocol is recommended for simple and rapid transformation. Champion™ Competent Cells are one of the fastest and simplest ready-to-use competent cell products in the world.
Kit contents
Champion™ Competent Cells
pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
Champion™ Transformation Protocol Card
Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.

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).
