The EZBioscience® EZ-press Serum/Plasma RNA Purification Kit provides a simple, reliable, and rapid method for isolating high-quality total RNA (including mRNA, miRNA, lncRNA, CircRNA, et.al.) from human and animal serum/plasma. The purified total RNA is suitable for use in a variety of downstream applications, including: RT-PCR, RT-qPCR, Northern blotting, nuclease protection assays, cDNA library preparation after poly (A)+ selection, RNA sequencing, and so on. Serum/plasma samples are first lysed and homogenized in a strong denaturant and phenol containing buffer, which immediately inactivates RNases to ensure isolation of intact RNA. After homogenization, Buffer A is mixed with the lysate and incubated for 3 minutes. And then the mixture is centrifuged for phase separation; the upper-layer supernatant is collected and mixed with ethanol. The liquid is then passed through the RNA binding Spin Column containing a silica-based membrane to which the RNA binds. Impurities are effectively removed by subsequent washing. The purified total RNA is then eluted with Elution Buffer and may be used in a variety of downstream applications.
EZB-RN2 (50 Preps)
Wash Buffer 1*
Wash Buffer 2*
Spin Columns (with Collection Tubes)
*Before using for the first time, add 32 ml of 100% ethanol to the Wash Buffer 1, 32 ml of 100% ethanol to the Wash Buffer 2.
Store the Lysis Buffer and Buffer A at 2 ~ 8°C, protect from light. Store other components at room temperature (When using these buffers, be careful to avoid of contamination). Divide the Elution Buffer into small aliquots upon reception is suggested.
