Thermo Fisher, AM1981, GLOBINclear™ Kit, mouse/rat, for globin mRNA depletion

Quantity: 20 Preps
Unit Size: Each
The Ambion™ GLOBINclear™-Mouse/Rat Kit employs a novel, non-enzymatic technology that rapidly depletes >95% of the alpha and beta globin mRNA from total RNA preparations derived from whole blood. The kit includes sufficient reagents for 20 reactions.• Remove >95% of unwanted globin mRNA from whole blood total RNA• Detect up to 50% more genes—analyze previously undetected genes• Achieve greater representation of the genome, low 3'/5' ratios• Avoid RNase H treatments that can degrade mRNA and alter expression profilesIt is widely known that expression array data generated from whole blood total RNA samples have reduced detection sensitivity compared to data from fractionated blood samples. Examination of whole blood total RNA reveals a dominant band in the 600–700 base region. This band represents globin mRNA, which is expressed at high levels in red blood cells (RBCs) and reticulocytes (RBC precursors). Up to 70% of the mRNA (by mass) in whole blood total RNA are globin transcripts. Array analysis using total RNA containing a high percentage of globin mRNA has been shown to:• Decrease present calls• Decrease call concordance• Increase signal variationThe GLOBINclear™ kit employs a novel hybridization technology that takes advantage of the strength of biotin/streptavidin binding, the specificity of nucleic acid hybridization, and the convenience of magnetic separations. There are no harsh RNase H enzymatic treatments that may compromise the expression profile by degrading mRNAs other than globin mRNA. The resulting mRNA is a superior template for synthesizing labeled cDNA for array analysis and is ideal for quantitative RT-PCR. The enrichment delivers a significant increase in Percent Present calls, decreased sample-to-sample variability, and low 3'/5' ratios.Accessory Product:The kit requires the use of a magnetic stand. The 6 Tube Magnetic Stand (SKU# AM10055) can hold six separate 1.5 mL conical microcentrifuge tubes or 2 mL round-bottomed microtubes with a diameter of 8–10 mm.
