Principle

Biological samples are first lysed and homogenized in a highly denaturing guanidine isothiocyanate-containing buffer, which immediately inactivates DNases and RNases to ensure isolation of intact DNA and RNA. The lysate is then passed through a Mini spin column. This column, in combination with the high-salt buffer, allows selective and efficient binding of genomic DNA. Flow-through from the column is digested by Proteinase K in the presence of ethanol. This optimized digestion, together with the subsequent addition of further ethanol, allows appropriate binding of total RNA, including miRNA, to the column. Contaminants are efficiently washed away and high-quality RNA is eluted.

Advantages

• High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
• Fast – several samples can be extracted in 40 minutes
• High applicability – samples including animals, plants, bacteria, cells, etc.
• High concentration – efficiently remove macromolecular RNA, enrich small RNA and improve sensitivity
• Safe – no phenol chloroform extraction and no use of Trizol reagent

Storage and Stability

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.

Mal-amido-PEG4-alkyne is a short PEG linker featuring a maleimide and a terminal alkyne. Maleimide is a covalent ligand used for linking thiols such as those in cysteines residues in proteins, while terminal alkynes can be used in copper (I) click chemistry with azides on target molecules.
