Bis-propargyl-PEG6 has two propargyl groups which can participate in Click Chemistry reactions to yield a stable triazole linkage with azide compounds; copper is needed as a catalyst. The 6 units of PEG increase the hydrophilicity of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples. Alternatively, a miRNA-enriched fraction and a total RNA (>200nt) fraction can be purified separately. This Kit combines phenol/guanidine-based lysis of samples and silica membrane–based purification of total RNA. MagZol Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of tissues, to inhibit RNases, and also to remove most of the cellular DNA and proteins from the lysate by organic extraction.

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such asguanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein andother impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
This kit combines acid/guanidine (MagZol) extraction technology with glass fiber filter membrane purification, which can improve the extraction effect of complex samples and samples with low RNA content. After the sample is treated with MagZol reagent and chloroform, the supernatant is added with ethanol to provide appropriate binding conditions, then transferred to the purification column and centrifuged. Macromolecular RNA can be efficiently bound to the membrane. Collect the filtrate containing small RNA, add more ethanol to adjust the binding capacity of small RNA, the pollutants can be efficiently washed away by second cleaning. Finally, the purified RNA was eluted by RNase free water.

Storage and Stability
MagZol Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

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:
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.
