Fractionate leukocytes from whole blood in minutes with provided RBC Lysis Buffer
Isolate total RNA, including microRNA, without phenol
Rapid and convenient spin-column format and 96-well plate for high throughput applications
Purified RNA is ready for any downstream application including RT-PCR, qRT-PCR, NGS, arrays and more. Find out more information on Norgen’s NGS services
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from mammalian blood samples. These kits are supplied with an RBC (red blood cell) Lysis Buffer for selective removal of red blood cells and fractionation of leukocytes by centrifugation. Isolation of leukocyte RNA results in improved expression profiling and other downstream applications by removing the masking effects of some RNAs which are very abundant in whole blood, such as globin mRNAs. These kits are able to isolate total leukocyte RNA, including both large mRNA and all small RNA species containing microRNA (miRNA) and small silencing RNA (siRNA). The purified RNA is of the highest quality and can be used in a number of downstream applications.
Leukocyte RNA Purification Kit (Spin Column)
This kit provides a rapid method for the isolation and purification of total leukocyte RNA from mammalian blood samples in 40 minutes. Allowable blood input ranges from 10 μL to 2 mL or 3 x 106 Leukocytes
Leukocyte RNA Purification Plus Kit (Plus)
Norgen’s Leukocyte RNA Purification Plus Kit provides a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from up to 3 mL of mammalian blood samples. Complete 10 purifications in as little as 40 minutes.
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Norgen’s kit allows for the isolation of total leukocyte RNA, including all small RNA species. The purified RNA is of the highest quality and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, northern blotting, RNase protection and primer extension, and expression array assays. Allowable blood input ranges from 10 μL to 1 mL or 1.5 x 106 Leukocytes.
