Norgen’s Cell Culture Media Exosome Purification and RNA Isolation Kits constitute an all-in-one system for the purification of exosomes and the subsequent isolation of exosomal RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The kit is designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

The Phytase Assay Kit is a simple, quantitative method which can be used to measure phytase activity. Analysis is based on the hydrolysis of phytic acid by phytase and quantitative measurement of the phosphate released. Results are measured using a standard UV-VIS spectrophotometer and do not require the creation of a standard curve. The Phytase method can be used to measure phytase activity in cereal, fungal and bacterial phytases, and can also be used for the analysis of phytase in animal feed samples.

Advantages
The NGS Low Input DNA Library Prep Kit (illumina and MGI Platforms) was developed for construction of high quality NGS libraries with low input DNA amount from 1 ng to 400 ng. The kit allows scientist to study samples with limited DNA such as tumor samples, patient samples, and other specially collected samples (FACS sorting etc.). The kit has high library conversion efficiency with as little as 1 ng DNA input. The fast and simple 1.5-hour protocol makes libraries with even coverage and low GC-bias based our unique chemistry for DNA end-polishing and ligation.
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 approach (for example, BioDynami DNA fragmentation enzymes, Cat.# 40061 and Cat.# 40062) and mechanical approaches such as sonication and nebulization etc.
NGS Low Input DNA Library Prep Kit Workflow
Three index types are available for the NGS Low Input DNA Library Prep Kit of illumina platform:
Non-index (Cat.# 30022): Libraries do not have index.
Index (Cat.# 30024): Each of our index primers contains a unique barcode sequence with 6 bases that can be used to identify the low input DNA libraries. Library multiplexing up to 48 samples is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30025): Library multiplexing up to 96 low input DNA libraries is possible with unique dual indexes with our Four-Base Difference Index System. The system allows us to make indexes for the libraries that have at least 4 bases different from each other in the 8-base barcode length. Our unique dual index primers can reduce sequencing errors such as de-multiplexing errors, amplification errors, mis-assignment of reads, index cross-contamination, and also index hopping. The kit includes 96 pre-mixed unique pairs of index primers. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34024).
