Propargyl-PEG10-NHS ester serves as a bifunctional PEG linker with a terminal propargyl that participates in click reactions with azide-bearing moieties and an NHS ester group that reacts readily and efficiently with amine-bearing molecules. The PEG10 units improve the water solubility of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

HiPure Insect DNA Kits provides a simple and rapid solution for total DNA extraction of insect tissue samples. This kit is based on silica gel column purification technology without toxic phenol chloroform extraction and time-consuming alcohol precipitation. The whole extraction process only takes 30 minutes. HiPure Insect DNA Kit can process tissue samples less than 10mg at a time. Hipure Insect DNA 96 kit can process 96 insect tissue samples at a high throughput. The obtained DNA can be directly used in PCR, Southern blot, viral DNA detection and other experiments.

Principles
This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their 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 entire kit can be stored at 2–8°C, but in thiscase buffers should be redissolved before use. Make sure that all buffers areat room temperature when used.

View Dietary Fiber Measurement Guide – Which Method for which sample?
Dietary fiber can generally be described as the carbohydrate content of food that is not digested in the human small intestine. It passes into the large intestine where it is partially or fully fermented. These characteristics of dietary fiber are associated with its numerous well documented health benefits.
Dietary Fiber is a mixture of complex organic substances, including hydrophilic compounds, such as soluble and insoluble polysaccharides and non-digestable oligosaccharides, as well as a range of non-swellable, more or less hydrophobic, compounds such as cutins, suberins and lignins. The procedures for the determination and analysis of total dietary fiber as outlined in our assay protocol are based on the methods of Lee et al.1 and Prosky et al.2,3 (AOAC 991.43, AOAC 985.29, AACC 32-07.01 and AACC 32-05.01). However, the enzymes in the Megazyme Total Dietary Fiber Kit can also be used in other dietary fiber analytical methods such as AACC Method 32-21.01 and AACC Method 32-06.01.

Two separate methods are described in the associated assay protocol:
METHOD 1: DETERMINATION OF TOTAL, SOLUBLE AND INSOLUBLE DIETARY FIBER
Based on AOAC Method 991.43 “Total, Soluble, and Insoluble Dietary Fiber in Foods” (First Action 1991) and AACC Method 32-07.01 “Determination of Soluble, Insoluble, and Total Dietary Fiber in Foods and Food Products” (Final Approval 10-16-91).
METHOD 2: DETERMINATION OF TOTAL DIETARY FIBER
Based on AACC method 32-05.01 and AOAC Method 985.29.
