What is RNA?

What is RNA?

Ribonucleic acid ( RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life.

Why choose our RNA extraction kits?

Our trusted RNA extraction kits ensure high yields of high-quality RNA free of contaminants and inhibitors. Streamlined protocols with optimized RNA extraction reagents simplify handling and are optimized for your specific sample types, formats and throughputs, as well as for manual and automated processing.

What is the range of rRNA bands found in poly (A) samples?

Note: Poly (A) selected samples will not contain strong rRNA bands and will appear as a smear from approximately 6 kb to 0.5 kb (resulting from the population of mRNAs, and depending on exposure times and conditions), with the area between 1.5 and 2 kb being the most intense (this smear is sometimes apparent in total RNA samples as well). Figure 1.

What is native agarose gel electrophoresis of RNA?

Native Agarose Gel Electrophoresis of RNA. Native agarose gel electrophoresis may be sufficient to judge the integrity and overall quality of a total RNA preparation by inspection of the 28S and 18S rRNA bands.
