PureLink™ RNase A (20 mg/mL) Invitrogen™

PureLink™ RNase A (ribonuclease A) is a bovine pancreatic ribonuclease that cleaves single-stranded RNA. This reagent is also a component of the PureLink™ plasmid purification system. Concentration 20 mg RNase A/mL in 50 mM Tris-HCl (pH 8.0), 10 mM EDTA.

UltraPure™ Urea Invitrogen™

UltraPure™ Urea is an effective protein denaturant. In a highly concentrated (6 to 8 M) urea solution, many proteins unfold and separate into their constituent polypeptide chains. UltraPure™ Urea is also used to denature nucleic acids in sequencing gels.

Thermo Scientific Pierce D-Luciferin, Monopotassium Salt is formulated at greater than 99% purity to provide convenience and high performance at a low cost in reporter assays involving firefly luciferase. Features of D-Luciferin, Monopotassium Salt: • Molecular mass = 318.

Pierce™ D-Luciferin, Monopotassium Salt Thermo Scientific™

Thermo Scientific Pierce D-Luciferin, Monosodium Salt is formulated at greater than 99% purity to provide convenience and high performance at a low cost in reporter assays involving firefly luciferase. Features of D-Luciferin, Monosodium Salt: • Molecular mass = 318.

UltraPure™ Phenol:Chloroform:Isoamyl Alcohol (25:24:1, v/v) Invitrogen™

UltraPure™ Phenol:Chloroform:Isoamyl Alcohol (25:24:1, v/v) is used in the purification of nucleic acids. This reagent consists of highly pure chloroform, isoamyl alcohol, and UltraPure™ Phenol saturated with Tris-HCl.

Yeast tRNA (10 mg/mL) Invitrogen™

Ambion™ Yeast tRNA purified from brewer's yeast. When used at a final concentration of 10–20 µg/mL, yeast tRNA is an effective coprecipitant to aid in recovery of small amounts of nucleic acids. It is supplied in one tube containing 0.5 mL at a concentration of 10 mg/mL. What is a Coprecipitant?

SSC (20X), RNase-free Invitrogen™

Molecular biology grade, Ambion® 20X SSC solution is supplied in four bottles containing 1 L each. The buffer is certified RNase-free, economical, and ready-to-use. Due to the ubiquitous presence of RNases, manufacturing products for use with RNA is especially challenging.
