dissolve RNA samples, Anal, At the end of the procedure, Avoid breathing vapor, B, BIOLOGICAL FLUIDS, Biochem, Boehringer Mannheim) to the aqueous phase is necessary for a 100 recovery of the RNA precipitate, CAN BE FATAL, CSF, Chomczynski P, Chomzynski P, Citation of the method: total RNA was isolated by the single-step method (2) using RNA STAT-50TM LS, Cold Spring, Cold Spring Harbor Laboratory, Cs-113, Dissolve the RNA pellet in FORMazolTM (Cat, Do not get on skin or clothing, Do not use the Speed-Vac for drying, Following centrifugation, Following homogenization (before addition of chloroform) samples can be stored at -70oC for at least two weeks, HOMOGENIZATION A, Hands and dust may be the major source of the RNase contamination, Harbor, Homogenization 0, Homogenize 0, If the expected yield of RNA is <, If the sample vol, In case of contact: Immediately flush eyes or skin with a large amount of water for at least 15 minutes and seek immediate medical attention, Isolation of RNA from small samples (<, It is important not to let the RNA pellet dry completely as this will greatly decrease its solubility, Lyse (or homogenize) samples in 0, Mix 0, N, NOTE: Should you use our RNase free purified water (Cat, NOTES AND COMMENTS 1, Next, PCR without DNAses added, REFERENCES 1, RNA EXTRACTION Following homogenization, RNA Extraction homogenate +0, RNA PRECIPITATION Transfer the aqueous phase to a fresh tube and mix with isopropanol, RNA Precipitation aqueous phase +0, RNA STAT-50 TM LS works on blood, RNA STAT-50TM LS does not contains chloroform, RNA WASH Remove supernatant and wash the RNA pellet once with 75% ethanol by vortexing and subsequent centrifugation at 7, RNA Wash 1 ml 75% ethanol, RNA precipitate (often invisible before centrifugation) forms a white pellet at the bottom of the tube, RNase protection assay, Read also the warning note on the bottle, SPECIAL HANDLING PRECAUTIONS The RNA STAT-50TM LS contains poison (phenol) and irritant (guanidinium thiocyanate), Sambrook J, Steps: 1, Store samples at room temperature for 5-10 min and centrifuge at 12, TISSUE SUSPENSIONS, The RNA STAT-50TM LS cotains phenol and Guanidinium, The SDS solution used for RNA solubilization should be made free of RNase by diethyl pyrocarbonate (DEPC) treatment, The final preparation of total RNA is free of DNA and proteins and has a 260/280 ration >, The total RNA is extracted with isopropanol, The volume of the aqueous phase is about 60% of the volume of homogenate, The volume ration of RNA STAT-50TM LS to sample should always be 3 to 1, Total RNA in H2O while DNA and proteins are extracted into an organic phase and interphase, Total RNA isolated by RNA STAT-50TM LS is pure without DNA contamination for Northern Blot, Total and exosomic RNA 1 step with RNA STAT50TM LS for total RNA purification from biopsies, Use at least 0, Use gloves and keep tubes closed throughout the procedure, Vortex or pass the pellet a few times through a pipette tip, When working with RNA STAT-50TM LS use gloves and eye protection (shield, add 0, adjust the volume with water, amniotic fluid, an addition of 5 ug of carrier tRNA or glycogen (molecular biology grade, and Maniatis T, and Sacchi N, animals, centrifuge the homogenate at 12, cover the samples tightly, dot blot hybridization, dry briefly the RNA pellet by air-drying or under vacuum (5-10 min), human samples, in vitro translation, is <, isopropanol and ethanol, mRNA profiling, molecular cloning, phenol-chloroform phase and the colorless upper aqueous phase whereas DNA and proteins are in the inter phase and organic phase, plants, poly A+ selection, safety goggles), serum, shake vigorously for 15 seconds and let them stay at room temperature for 2-3 minutes, store the homogenate for 5 minutes at room temperature to permit the complete dissociation of nucleoprotein complexes, the homogenate separates into two phases: a lower red, washed with ethanol and water
