This kit provides a convenient and rapid method to purify total RNA from small amounts of stool samples. All types of stool samples can be processed with this kit, including animal fecal samples, manure and samples collected using Norgen’s Stool Nucleic Acid Collection and Transport Devices Dx (Cat. Dx45660). The kit removes all traces of humic acids using rapid and simple spin column procedures. Bead tubes are also provided for effective homogenization of stool. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA and small interfering RNA. Both host and microbial RNA is recovered. The protocol does not rely on the use of phenol or chloroform, thereby providing a user friendly procedure and allowing high-throughput analysis. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR and reverse transcription PCR for gene expression analysis. The procedure can be completed in approximately 30 minutes.
NOTE: This product is not available for sale in the United States.

The Norgen FullRanger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our FullRanger contains sixteen discrete fragments ranging from 100 bp to 5000 bp with higher intensity reference bands at 500 bp and 1000 bp. This Ladder is ideal for accurate visual determination in both large and small cloning applications.
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Norgen’s 2X One-Step RT-PCR Master Mix is a ready-to-use solution that contains components required for RT-PCR amplification of RNA templates. The mix includes M-MuLV reverse transcriptase, Taq DNA polymerase, dNTPs, reaction buffer, MgCl2, KCl, and a PCR enhancer/stabilizer. The user needs only to add the template, the primer set and water to the Master Mix to set up the RT-PCR reaction. This convenient 2X One-Step RT-PCR Master Mix reduces the time required to set up PCR reactions and reduces the possibility of contamination, particularly when preparing large numbers of reactions. The optimized master mix allows for robust amplification of RNA templates with high yields of PCR products.
Taq DNA Polymerase is a highly thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity and a very low 5´→ 3´ exonuclease activity. The source of Taq included with Norgen’s 2X One-Step RT-PCR Master Mix is an E. coli strain with a cloned Taq DNA Polymerase gene from Thermus aquaticus YT-1. M-MuLV Reverse Transcriptase is an RNA-directed DNA polymerase that can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template. The source of the Reverse Transcriptase included with Norgen’s 2X One-Step RT-PCR Master Mix is an E. coli strain with a cloned reverse transcriptase gene from M-MuLV.
Norgen’s 2X One-Step RT-PCR Master Mix is available in 3 convenient sizes:
Cat # 28113 – 100 reactions (sufficient for 100 reactions x 20 µL reaction volume)
Cat # 28114 – 200 reactions (sufficient for 200 reactions x 20 µL reaction volume)
Cat # 28115 – 500 reactions (sufficient for 500 reactions x 20 µL reaction volume)

Storage Conditions and Product Stability
2X One-Step RT-PCR Master Mix should be stored at -20°C. For everyday use an aliquot can be stored at 4°C for up to 3 months. Repeated freeze-thaw cycles are not recommended. When stored at the proper temperature this reagent is stable for at least 1 year.
