Purification of mRNA with CIMmultus™ Oligo dT

CIMmultus Oligo dT is a hybridization-affinity chromatography monolith for purification of mRNA that terminates in a poly-A tail. Non-RNA contaminants flow through the column during sample loading. RNA with a poly-A terminus binds. The column is washed then the mRNA is recovered in a single elution step at neutral pH. CIMmultus Oligo dT can be used for one-step purification of research grade ssRNA, as a high-resolution capture method in a multi-step purification process, as a polishing method, or as an analytical method for estimating quantity and purity of mRNA in a sample. It can be used with mRNA up to 10 kb or more.
