Propargyl-PEG24-amine is a linker with 24 PEG units. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl group is reactive with azide compounds under the catalyzation of copper. This linker has pretty good water-solubility due to its long PEG chain. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
Excellent separation and purification of cytoplasmic and nuclear RNA
Convenient and fast spin column format
High quality and yield of RNA
Isolate full diversity of RNA (including microRNA) without phenol
Purified RNA is ready for any application including RT-PCR, qRT-PCR, RNA-Seq, arrays and more
Cytoplasmic RNA is free of DNA and ready for direct use in RT-PCR/qRT-PCR
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a rapid method for the isolation and purification of both cytoplasmic and nuclear RNA from cultured animal cells and small tissue samples. The kit can be used to isolate all sizes of RNA from the cytoplasmic and nuclear RNA fractions, including all small RNA species without any requirement for phenol. Included in the kit are sufficient reagents to perform either 50 cytoplasmic RNA preparations or 25 cytoplasmic and 25 nuclear RNA preparations. Ten samples can be processed in approximately 45 minutes. This kit is also available in a 100 prep size.
Background
In certain circumstances it is desirable to be able to isolate fractionated RNA as opposed to total RNA. For example, it may be preferable to isolate only mature, cytoplasmic RNA for some studies on expression profiling. Alternatively it may be desirable to isolate nuclear RNA in order to investigate and study pre-processed (non-spliced) RNA. Furthermore, this kit can be used to isolate RNA for downstream applications where it is necessary to avoid DNA contamination, since the cytoplasmic fraction has been shown to be free of all traces of genomic DNA.

NGS FFPE DNA Library Prep Kit (illumina and MGI Platforms)
Product Info
Document
Product Info
The NGS FFPE DNA Library Prep Kit (illumina and MGI Platforms) was developed for the construction of high quality FFPE DNA libraries using 10 ng to 400 ng of input DNA isolated from formalin-fixed, paraffin-embedded (FFPE) samples. The DNA damage caused by fixation makes it difficult to construct high quality libraries. Our kit has been optimized to repair damaged DNA in the reactions. Multiplexing of the NGS FFPE DNA Library is possible.
NGS FFPE DNA Library Prep Kit Workflow
FFPE samples are a great resource for biomedical research. However, the methods for fixation and condition of storage significantly damage the DNA in the samples. Thus, the extraction of high quality DNA from FFPE samples is often a challenge. Low yield and low quality of FFPE DNA usually are common because of the limited tissue material and the DNA degradation.
As a result, it is usually difficult to construct high quality NGS libraries from low amount and low quality of FFPE DNA. In order to address this issue, we have developed the NGS FFPE DNA Library Prep Kit to make high quality libraries from the low input of FFPE DNA samples.
Three index types are available for the NGS FFPE DNA Library Prep Kit of the illumina platform:
Non-index (Cat.# 30035): Libraries do not have index.
Index (Cat.# 30037): Each of our index primers contains a unique barcode DNA (6 bases long) that can be used to identify individual library. Multiplexing of libraries is up to 48 samples. Index information can be downloaded here.
Unique dual index (Cat.# 30039): FFPE DNA library multiplexing is possible with 96 samples based on the unique dual indexing system. Our unique Four–Base Difference Index System allows us to make indexes that have at least 4 bases different from each other in the 8-base index sequence. Our unique dual indexing primers can effectively remove NGS errors including index hopping, de-multiplexing errors, index cross-contamination, mis-assignments etc. The unique dual index primer set includes 96 pre-mixed unique pairs of i5 and i7 index primers. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34037).
