DBCO-TFP ester

Propargyl-PEG6-acid comprises propargyl and carboxylic acid functional groups. The acid group reacts with primary amines in the presence of activators (e.g. EDC, or HATU).The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The molecule has good solubility in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description

The EzRNA™ RNA Capping System is a user-friendly product for post-transcriptional RNA modification. Both Vaccinia Capping Enzyme and 2’-O-Methyltransferase are included in the package, which are able to perform in a single reaction. The Vaccinia Capping Enzyme attach 7-methylguanylate cap (m7Gppp, Cap-0) to the 5′ end of RNA to form m7Gppp5’N-RNA (Cap-0 RNA). The 2′-O-methyltransferase utilizes Cap-0 RNA as a substrate, employing S-adenosine methionine (SAM) as a methyl donor to methylate 2′ -OH of the first nucleotide at the 5′ end of Cap-0 RNA, resulting in the formation of Cap-1 RNA.

Features

• 2’-O-Methyltransferase included for Cap-1 RNA
• High capping efficiency
• High stability
• RNase inhibitor is included to enhance the stability of capping reaction

Application

• Generation of 5’Cap-0 (m7Gppp) and Cap-1 (m7GpppNm-) RNA by enzymatic reaction
• mRNA synthesis for in vitro translation
• Gene expression studies
• mRNA vaccine development and therapeutics

Storage

-20°C for 24 months

Overview

• Isolate DNA from a wide range of food materials. (e.g boiled, fluid, processed or raw food products)
• No hazardous chemicals required (e.g. phenol or chloroform)
• Effective lysis with Proteinase K and optional lysozyme treatment
• Fast (less than 15 minutes hands-on time) and convenient processing using a rapid spin-column format
• Wide compatibility with a variety of food products for GMO-DNA isolation
• Universal protocol for food related pathogen DNA isolation (Gram positive and Gram negative)

This kit provides a rapid spin column method for the isolation and purification of total DNA from a wide range of food samples originating from animals or plants. The kit is designed for identification of GMO-DNA or animal components in food and feed and can be used for a wide range of starting materials including raw or processed food, meat, liquids, sauces and dairy products including milk, cheese and yogurt.

This kit also provides a convenient method for the detection of food-related pathogens and will isolate such DNA (enriched or as is) including Gram-positive bacteria, Gram-negative bacteria, yeast and fungi which may contaminate food sources.  A number of pathogens have been tested including E. coli O157:H7, Staphylococcus, Listeria monocytogenes, Salmonella enterica & Campylobacter jejuni.  The purified DNA is of the highest integrity, and can be used in a number of downstream applications including PCR based detection, sequencing and genotyping.
